Jura GIGA 10 review: two grinders, 35 drinks and real cold brew from one very big machine
The Jura GIGA 10 15527 Automatic Espresso Machine is a two-grinder flagship that lets you switch or blend beans for every drink, make cold extraction coffee and fine-tune milk, foam and temperature separately. It's spectacular to use, but it's big, heavy and only worth it if you'll use its range.

In this review
Yes, if you want the most flexible home coffee machine I've tested and have the space and budget for it. The Jura GIGA 10 has two hoppers and two ceramic grinders, so you can keep a dark roast and a light roast side by side, or decaf and regular, and even blend them per drink. It makes 35 drinks, including cold extraction coffee, and lets you set coffee, milk and foam temperatures separately. It's big, heavy and expensive, and the programmed americano isn't a true two-step one.

First impressions of the Jura GIGA 10
The Jura GIGA 10 is a big machine in every sense.
It's about 41.5 centimeters tall and weighs around 18 kilograms, so lifting it onto the counter is a two-person job.
Two bean hoppers sit side by side on top, each with its own grinder underneath.
The front is dominated by a wide panoramic touchscreen and two movable coffee spouts.
The power button hides under the front panel, the only control in that area.
It all looks clean and serious, more like a café machine than a kitchen gadget.
My first test was the obvious one.
I loaded a dark Italian-style roast on the left and a light Ethiopian on the right.
Then I made two espressos back to back, one from each hopper.
Same machine, two completely different coffees, without emptying anything.
That's the GIGA 10's big idea, and it works brilliantly.
Two hoppers on top, two grinders underneath and two espressos at once.
What the Jura GIGA 10 actually is
The GIGA 10 is Jura's flagship home machine.
It's a fully automatic, bean-to-cup espresso machine with two hoppers, two grinders, a milk system and 35 programmed drinks.
You can brew from the left hopper, the right hopper, a blend of both, or pre-ground coffee through the bypass chute.
It also adds features you rarely see on home machines.
There's a cold extraction mode for cold brew-style coffee.
You can adjust the foam texture, and set coffee, milk and foam temperatures separately.
And the grinders adjust electronically, so you set grind size from the screen.
Jura GIGA 10 design and setup
Measure your space before you buy the Jura GIGA 10.
It's about 32 × 41.5 × 49.6 centimeters, or 12.6 × 16.1 × 19.3 inches.
At over 16 inches tall, it may not fit under some wall cabinets, and you need extra space above it to fill and lift out the hoppers.
The water tank
The water tank holds about 2.6 liters, or 88 ounces.
That's much more than most home machines, which tend to hold around 2 liters.
In my house, it lasted two to three days.
The hoppers
Each hopper holds about 280 grams and locks into place.
You can lift a hopper off without emptying it, which makes switching beans easy.
The spouts and drip tray
Two coffee spouts slide up and down for anything from espresso cups to tall latte glasses.
The drip tray sits under the outlets and catches brewing and rinsing water.
The grounds container holds about 20 pucks.
Our tip: Measure the space between your counter and wall cabinets before buying, and leave a few extra inches to lift the hoppers out.
The GIGA 10 fits under taller cabinets, but check the clearance for the hoppers.
Two hoppers, two ceramic grinders
This is the GIGA 10's headline feature.
Each hopper feeds its own ceramic grinder.
Ceramic burrs transfer less heat than some other materials, which matters because heat can strip away delicate aromas, especially when grinding for big drinks.
Why two grinders are useful
In four weeks, I found several uses for the second grinder.
| Setup | Left hopper | Right hopper |
|---|---|---|
| Hot and cold | Dark roast for espresso and milk drinks | Medium roast for cold extraction |
| Two people | One person's favorite blend | The other person's single origin |
| Evening coffee | Regular beans | Decaf |
| Custom blend | Chocolatey base | Bright, fruity accent |
Blending per drink
For each drink, you choose the left grinder, the right grinder or a split between both.
I made a cappuccino with 70% dark roast and 30% Ethiopian, and it had body plus a bright, fruity lift.
It's a fun way to experiment without buying a pre-blended bag.
Grind adjustment
The grinders adjust electronically.
Instead of numbered settings, the screen shows a visual strength indicator.
Tapping the brown indicator opens grinder customization.
It took me a few days to get used to the visual scale, but it's easy once you know it.
Share of coffee from each grinder.
Our tip: Keep decaf in one hopper, so evening coffee is just a tap away instead of a trip to the pre-ground chute.
Jura GIGA 10 espresso performance
The GIGA 10 uses Jura's Pulse Extraction Process✕Pulse Extraction Process (P.E.P.)Jura's method of pushing hot water through the coffee in short, rapid bursts instead of one steady stream. It lengthens contact time for short drinks, giving a fuller flavor. for short drinks.
Combined with fresh, cool-ground coffee from the ceramic grinders, it produced the best espresso I've had from an automatic machine.
How it tasted
With the dark roast, the espresso had a thick, deep-brown crema✕CremaThe golden-brown foam on top of an espresso. It forms when pressure pushes gases and oils out of freshly ground coffee., a heavy body and flavors of dark chocolate and caramel.
With the light Ethiopian, it was bright and floral, with jasmine and berry notes that came through clearly.
Having both on tap changed how I drank coffee.
I chose beans by mood rather than by what happened to be in the hopper.
Customizing each drink
Each drink stores its own temperature, strength, volume and grinder choice.
You can change settings for one cup, or save them permanently as a personal recipe.
Drinks can even be renamed, so "Espresso" can become "Mike's espresso".
Sizes appear as small, medium and large rather than ounces, and the coffee indicator darkens as you add strength.
| What you taste or see | Likely cause | First change |
|---|---|---|
| Sour, thin | Light roast under-extracted | Increase strength or grind finer |
| Bitter, harsh | Dark roast over-extracted | Grind a little coarser or shorten volume |
| Muddy flavor in a blend | Clashing beans | Try a different split |
| Pale crema | Stale beans | Use fresher beans |
| Lukewarm shot | Low temperature setting | Raise coffee temperature |
Cold extraction
The GIGA 10 can make cold brew-style coffee with its cold extraction✕Cold extractionBrewing coffee with cool water instead of hot. It pulls out fewer bitter compounds and less acidity, for a smoother, sweeter drink. mode.
Instead of hot water, it pushes cold water through the coffee slowly and in pulses.
What to expect
The first time, I thought something was wrong.
The coffee came out very slowly, sometimes just a drop at a time at the start, and the machine made a noticeable vibrating sound.
That's completely normal.
The slow flow is how the machine gets flavor out of cold water in minutes rather than hours.
Grind for cold drinks
Cold extraction works best with a medium or slightly coarser grind than espresso.
This is where the second grinder really earns its place.
I kept a medium roast on the right, ground a little coarser, just for cold drinks.
How it tastes
The cold coffee was smooth, sweet and low in bitterness, with a clean finish.
Over ice with a splash of milk, it was my favorite afternoon drink during a warm week.
It isn't the same as a 12-hour steep, which has a heavier, more syrupy body, but it's very good for a drink made in minutes.
My tasting notes on a 10-point scale.
Our tip: Use a medium roast in one hopper for cold extraction, because very dark roasts can taste flat when brewed cold.
Milk foam and milk drinks
The GIGA 10's milk system is the most adjustable I've used on a Jura.
For each milk drink, you can set the milk quantity, the foam quantity and the foam's texture.
The machine switches automatically between milk and foam during the drink.
Separate temperatures
You can set the temperature of the coffee, the milk and the foam separately.
With all three on high, my cappuccino came out genuinely hot.
For an afternoon flat white, I lowered the milk temperature so it was ready to drink straight away.
Making a cappuccino your own
Press and hold the cappuccino icon to open its settings.
| Step | What you set |
|---|---|
| 1 | Grinder: left, right or a split |
| 2 | Coffee strength and amount |
| 3 | Milk quantity and foam quantity |
| 4 | Drink size |
| 5 | Coffee, milk and foam temperatures |
| 6 | Save permanently, or use once |
A medium coffee setting doesn't mean a medium finished drink, because the milk adds volume.
It took me a couple of tries to get my cappuccino to fill my favorite cup exactly.
Milk choice
Cold 2% cow's milk gave the most consistent microfoam✕MicrofoamMilk foam with bubbles so small you can't see them. It feels silky and blends into the coffee instead of sitting on top like froth. in my testing.
Whole milk was richer, and plant-based milks varied a lot by brand.
My ratings on a 10-point scale for texture and stability.
A stainless milk container sits beside the GIGA 10 for milk drinks.
Americano and long coffee
The programmed americano combines water and coffee during extraction.
The result is closer to a lungo than a classic americano✕AmericanoAn espresso topped up with hot water. Because the extra water doesn't pass through the coffee, it tastes cleaner and less bitter than one long brew..
It's good, with a rich color and a nice crema, but it isn't the clean, bright two-step drink some people want.
For a traditional americano, brew an espresso and add hot water from the separate hot water spout.
It's two steps, but you get full control over the strength.
The panoramic touchscreen
The 6.7-inch panoramic touchscreen is a highlight.
It shows nine drinks per screen across three main panels.
You can pin one favorite drink to the center position.
During preparation, the screen shows each stage, and the graphics change as you adjust settings.
The learning curve
With 35 drinks and so many settings, the GIGA 10 takes a few days to learn.
Visual indicators replace numbers, which is friendly once you understand them but confusing at first.
After a week, I could set up a new drink in seconds.
The app
The GIGA 10 connects over Wi-Fi to Jura's J.O.E. app.
It's handy for creating recipes, but the big touchscreen makes the app optional.
Our tip: Pin your most-used drink to the center position on the touchscreen, so it's always one tap away.
Pre-ground coffee
The pre-ground coffee✕Pre-ground bypassA separate chute that sends already-ground coffee straight to the brew unit, skipping the grinder. Handy for decaf without emptying the bean hopper. chute takes up to two level scoops.
A sensor checks whether you've added coffee and whether it's enough.
If not, the machine tells you, which prevents weak, watery drinks.
With two hoppers, I used the chute far less than on other machines, mostly for trying sample bags.
Cleaning and maintaining the Jura GIGA 10
The GIGA 10 tells you what it needs and when.
The machine rinses its coffee path when it switches on and off.
After milk drinks, it prompts a milk rinse, and it asks for a deeper milk system clean with Jura's milk cleaner when needed.
I rinsed the milk spout parts under warm water every few days.
The brew unit is cleaned automatically with tablets when prompted.
With the CLEARYL Smart+ filter installed, descaling✕DescalingRunning a mild acid solution through the machine to dissolve mineral scale left by hard water. Scale slows heating and can block pipes. is rarely needed.
| When | Task | Why it matters |
|---|---|---|
| After milk drinks | Run the milk rinse | Clears milk from the system |
| Every few days | Rinse the milk spout parts | Removes dried milk |
| Every few days | Empty grounds container and drip tray | About 20 pucks fit |
| When prompted | Milk system clean with cleaner | Removes milk fat |
| When prompted | Brew unit tablet cleaning | Strips coffee oils |
| When prompted | Filter change | Controls mineral scale |
My estimate of hands-on daily cleaning time.
Daily use
My mornings started with an espresso from the left hopper.
In the afternoon, I'd make a cold extraction from the right hopper over ice.
The big tank and 20-puck grounds container meant far less refilling and emptying than on smaller machines.
Rough maths from a 2.6 L tank, two 280 g hoppers and a 20-puck bin, allowing for rinse water.
The big water tank lasted two to three days in my house.
My four weeks with the GIGA 10
Week one: learning the machine
Week one was about learning the touchscreen and the visual settings.
I spent time setting up four personal recipes: espresso, cappuccino, flat white and cold extraction.
Week two: two beans
In week two, I settled on a dark roast on the left and a medium roast on the right.
The dark roast went into espresso and milk drinks, and the medium roast into cold extraction.
Week three: blending
In week three, I started blending.
A 70/30 split became my house cappuccino.
Week four: decaf and guests
In week four, I swapped the right hopper for decaf for a dinner party.
Guests could choose regular or decaf espresso without me opening anything.
Recipes I made on the GIGA 10
The GIGA 10's range made it fun to experiment.
These are the recipes I came back to most often.
Iced cold extraction latte
Run a cold extraction from the medium-roast hopper over a glass full of ice.
Top it with cold milk, or a portion of milk foam set to its lowest temperature.
It's smooth, sweet and refreshing, with none of the watery taste you get from hot espresso poured over ice.
Split-shot flat white
Set a flat white to draw 70% from the dark roast and 30% from a bright single origin.
Lower the milk temperature a little so the sweetness comes through.
It has body from the dark roast and a lively finish from the light one.
Evening decaf cappuccino
Put decaf in the right hopper and save a cappuccino recipe that only uses that grinder.
Name it "Evening cappuccino" so nobody grabs a caffeinated one by mistake.
Extra-shot latte macchiato
For a stronger milk drink, use the extra-shot version of the latte macchiato.
The second shot settles between the milk and the foam, and the layers look great in a tall glass.
| Recipe | Grinder | Key settings |
|---|---|---|
| Iced cold extraction latte | Right, medium roast | Cold extraction, cold milk |
| Split-shot flat white | 70% left, 30% right | Slightly lower milk temperature |
| Evening decaf cappuccino | Right, decaf | Saved and renamed recipe |
| Extra-shot latte macchiato | Left, dark roast | Extra-shot option |
Our tip: Rename your saved recipes with the bean or the person's name, so everyone in the house knows which drink is theirs.
Living with a flagship
A machine at this level is meant to last for years, so it's worth thinking past the first month.
Build and materials
The GIGA 10 is made in Switzerland and feels solid throughout.
The hoppers lock firmly, the spouts glide smoothly and nothing rattled during my test.
Consumables
Over a year, you'll buy filters, cleaning tablets and milk system cleaner.
The machine tracks when each one is due, so you never have to guess.
Buying them in multi-packs keeps the cost down.
Two grinders, twice the care
Two grinders mean two hoppers to keep clean.
Every few weeks, I wiped out the hoppers with a dry cloth to remove bean oils and dust.
Oily beans are best avoided in both, because they can clog a grinder over time.
Warranty
Jura covers the GIGA 10 with a two-year warranty.
Check the exact terms where you buy, because registration and coverage can vary by retailer.
Our tip: Wipe both bean hoppers with a dry cloth every few weeks, so old oils don't turn the next bag stale.
Beans and milk
The GIGA 10 rewards good beans more than most machines, because you can compare two side by side.
Use fresh beans within a few weeks of the roast date, and avoid very oily ones.
| Bean or milk | How it worked | Best use |
|---|---|---|
| Dark roast blend | Thick crema, chocolate and caramel | Espresso and milk drinks |
| Medium roast | Sweet and balanced | Cold extraction, americano |
| Light single origin | Floral, bright | Espresso, or blended 30% with dark |
| Decaf | Good with fresh beans | Evening drinks, in its own hopper |
| 2% milk | Most consistent foam | Cappuccino and flat white |
Common mistakes to avoid
The Jura GIGA 10 is powerful, but a few habits make a difference.
| Mistake | What happens | Better habit |
|---|---|---|
| Thinking slow cold extraction is a fault | You stop a good drink | Let it drip, it's normal |
| Using an espresso grind for cold extraction | Very slow, over-extracted | Grind medium or coarser |
| Not measuring the space above | Hoppers won't lift out | Leave clearance above |
| Underfilling the pre-ground chute | Weak, watery drink | Follow the sensor's warning |
| Expecting a two-step americano | Tastes like a lungo | Add hot water manually |
What I would change
I'd add a true two-step americano and numbered grind settings alongside the visual scale.
A slightly smaller footprint would also make it fit more kitchens.
Is the Jura GIGA 10 worth the money?
The GIGA 10 sits at the very top of Jura's home range.
Its value depends entirely on how much of its range you'll use.
If you'll use both hoppers, cold extraction and the milk settings, nothing else I've tested offers this much flexibility.
If you only want a cappuccino and an espresso from one bean, you're paying for features you'll never touch.
Ask yourself three questions before you buy.
Will you really use two different beans? Do you drink cold brew or iced coffee? And do you have the space, including above the machine?
If the answers are yes, the GIGA 10 is a spectacular machine to live with.
How it compares with other espresso setups
The most useful comparison is with the types of machines you're likely choosing between.
The Jura GIGA 10 stands out for its two grinders and its milk and temperature control.
| Feature | Jura GIGA 10 | Single-grinder premium machine | Manual machine and two grinders |
|---|---|---|---|
| Beans ready to use | Two, or a blend | One | Two, by hand |
| Cold extraction | Yes | Sometimes | No |
| Milk foam control | Quantity, texture and temperature | Often adjustable | Steam wand, skill-dependent |
| Drinks | 35 programmed | Often 15–25 | Anything, by hand |
| Footprint | Very large | Medium to large | Large, several devices |
| Learning curve | Moderate | Low | Steep |
A single-grinder premium machine is smaller and costs less, but you're limited to one bean at a time.
A manual setup with two grinders gives full control, but takes skill and time every day.
The GIGA 10 gives you two-bean flexibility at the touch of a screen.
| You mostly drink | Is the GIGA 10 a fit? | Why |
|---|---|---|
| Espresso with different beans | Excellent | Two grinders, blends |
| Cappuccino and flat white | Excellent | Adjustable foam and temperatures |
| Cold brew | Excellent | Cold extraction |
| Classic americano | Good | Two steps with the hot water spout |
| One simple drink | Poor value | You'd pay for unused features |

Other Jura machines I tested
The Jura Z10 also does cold extraction, with one self-adjusting grinder in a smaller body.
The Jura J8 is the step down for milk drinks, with Sweet Foam.
If you're buying for an office, my Jura X10 review covers a machine rated for about 100 cups a day.

4 quick questionsJura GIGA 10 specifications
From manufacturer data and my own testing.
How I tested and scored the Jura GIGA 10
For four weeks, I used the Jura GIGA 10 as my everyday machine for espresso, americanos, cold extraction drinks, cappuccinos, flat whites and latte macchiatos.
I kept a dark roast in one hopper and a light roast or decaf in the other, and tested single-grinder and blended drinks.
I customized coffee, milk and foam temperatures, saved personal recipes, tried pre-ground coffee and followed the machine's care prompts.
I then checked my notes against Jura's specifications and owner documentation.
- Espresso (9.2): crema, body, flavor and the two-grinder flexibility.
- Milk drinks (9.1): foam texture, adjustable foam and separate temperatures.
- Ease of use (8.6): touchscreen, personal recipes and the learning curve.
- Cleaning (8.2): milk system care, maintenance prompts and drip tray.
The overall score of 8.9 is an editorial rating that reflects those four areas.
Jura GIGA 10 FAQ
Is the Jura GIGA 10 worth it?
Yes, if you'll use its range: two beans, cold extraction and highly adjustable milk drinks. If you only drink one or two simple drinks, a smaller single-grinder machine is better value.
Why does the Jura GIGA 10 have two grinders?
Each hopper has its own ceramic grinder, so you can keep two different beans ready, such as a dark roast and decaf, and choose either one or a blend of both for each drink.
Can the Jura GIGA 10 make cold brew?
Yes. Its cold extraction mode brews coffee with cold water in a few minutes. It runs slowly, sometimes drop by drop at first, which is normal.
How many drinks does the Jura GIGA 10 make?
It has 35 programmed drinks, including espresso, coffee, americano, cappuccino, flat white, latte macchiato, extra-shot drinks and cold extraction drinks.
Can I adjust the milk foam?
Yes. You can set the milk quantity, foam quantity and foam characteristics, and set coffee, milk and foam temperatures separately.
How big is the Jura GIGA 10?
About 32 × 41.5 × 49.6 cm, or 12.6 × 16.1 × 19.3 inches, and about 18 kg. It needs room above it to fill and remove the hoppers.
How big is the water tank?
About 2.6 liters, or 88 fluid ounces, which is much larger than most home machines.
Is the programmed americano a true americano?
Not quite. It combines water and coffee during extraction, so it tastes closer to a lungo. For a classic americano, brew an espresso and add hot water from the separate spout.
Can I use pre-ground coffee?
Yes. Add up to two level scoops to the bypass chute. A sensor checks that you've added enough and warns you if not.
What milk works best?
Cold 2% cow's milk gave the most consistent foam in my testing. Plant-based milks varied by brand.
Does the Jura GIGA 10 have an app?
Yes. It connects over Wi-Fi to Jura's J.O.E. app.
