Jura GIGA 10 Review: Two Grinders for Homes That Drink Two Coffees

Specs current as of October 2026.

Two grinders keep regular and decaf loaded at the same time

The GIGA 10 has two bean containers on top, and each one feeds its own grinder. A drink can use either coffee or a blend of the two in steps of 25%, so a half-caf (half regular, half decaf) is a setting you save once and pick from the screen. Most owners bought the GIGA 10 for this. One owner runs regular coffee through the day and decaf toward evening, and two months in he calls the two grinders "the best ever" for his household. An owner who is sensitive to caffeine blends the two containers every day, and another keeps decaf in one side for his wife. In homes where everyone drinks caffeinated coffee, owners use the second container for a second roast, such as an espresso roast on one side and a coffee they are trying out on the other.

The two grinders use ceramic burrs, the two ridged discs that crush the beans, and each grinder has five settings from very coarse to very fine. You set each grinder once in the menu, and every drink from that container uses the setting. Owners keep most coffees on fine, because the very fine setting can clog the machine with dark roasts and some decafs. Jura told one owner to use the coarse setting for oily beans, the ones with a shiny surface, and he moves the setting one step at a time. An owner who has used his GIGA 10 since 2024 finds that medium and medium-dark roasts suit it best.

Owners find the coffee better than their previous machines

About eight owners say the GIGA 10 makes better coffee than the machine it replaced. An owner moving from a ten-year-old De'Longhi got "much better results" from the same beans, and an owner who replaced a Miele says the same. Another replaced a Breville with a built-in grinder because his drinks varied from cup to cup, and three months in he says the GIGA 10 makes the same drink every time with less work. Two owners add that the GIGA 10 uses fewer beans than their drip coffee maker did, so they now buy better coffee.

Each drink is one tap once you set it up

The touch panel shows the drinks in a wide row, and one owner arranges it so each person's usual drink sits on the first screen. Strength, size, milk and foam are sliders. A change you make before the drink starts applies to that cup only. The coffee and milk pour from one spout head, so a latte needs one tap and the cup stays in place. The GIGA 10 also switches itself on and off on a schedule, and several owners use it, one with the machine set to switch on at 5 am. The power switch sits under a flap on top, and owners open the flap by pressing its back edge.

A few minutes after a milk drink, the GIGA 10 rinses its milk spout with hot water, so collect your cup before then. On days you make milk drinks, the milk system runs a cleaning cycle with a cleaning tablet, which owners start at the end of the day. The 2.6 L tank is opaque, and the machine tells you when the water runs low; one owner fills it each night. Coffee grounds collect behind the drip tray, and owners wipe that space out once a week.

Drink sizes run from XS to XXL, and Jura publishes a chart in millilitres

The GIGA 10 sets each drink's size as XS, S, M, L, XL or XXL, and each size means a different volume for each drink. By one owner's measurements, a medium espresso is about 50 ml and a medium coffee about 140 ml. Jura publishes a chart of the millilitres for each size, and owners keep a printed copy beside the machine. About ten owners raise the sizes, more than any other complaint. Two owners set each drink once to fit their cups and rarely change it.

The steps between sizes are fixed, which matters most to people who drink black coffee. The Americano is mixed inside the machine, and an owner who wanted a size between two steps found the nearest sizes slightly too strong or too weak. For a bigger black coffee, owners pick the lungo, which runs to about 350 ml at XXL.

Lattes come out at about 55°C, and a warm cup helps

Owners who measured the milk in a latte found it at about 53 to 56°C (127 to 132°F) on the hottest setting, and about five owners would like it hotter. One owner found a better result by making an espresso and then the separate milk program, which gave milk at about 67°C (153°F). Others warm their cups first in Jura's cup warmer drawer or use a double-walled glass, which keeps the drink hot longer.

Owners describe the foam as fine and even, close to what a coffee shop serves.

The GIGA 10 brews 11 drinks cold, and owners split on the taste

The GIGA 10 brews cold versions of 11 drinks, from espresso to latte macchiato (a tall glass of milk with espresso poured in), using cold water in place of hot, which Jura calls the Cold Extraction Process. Owners whose families drink iced coffee like it, and one owner keeps one bean container set coarser for the cold drinks. Other owners find the cold coffee weaker than hot espresso poured over ice and use the hot version instead. In a cold drink with milk, the machine still heats the milk, so owners add ice.

Most early faults trace to shipping damage and the grinders

The GIGA 10 reached buyers in North America in 2023, so the longest owner reports run about three years. Long-term owners mostly report steady use: one reports more than 2,000 trouble-free drinks, one has used his for three years, and another has had his since July 2024 with one repair in the first months.

Owners report five faults most often. About four owners found the drip tray cracked in shipping, which lets water seep onto the counter, and Jura mailed a new tray to the owners who called. Five or six owners saw Error 14, a fault in a grinder's motor, mostly in the first days, and all but one had a factory-refurbished machine. Two of them returned the machine, one fixed it himself, Jura replaced or repaired two, and one was still waiting on Jura. About four owners had leaks from inside the machine, and two of them returned it. About five owners had milk that sputtered; owners traced it to dried milk on the small rubber rings in the spout, a loose connector or another brand's milk tube, and one sent the machine in for service. Two owners had a machine that stopped recognising the drip tray. Of the 12 owners who reviewed the GIGA 10 at one large US retailer, all of whom received an incentive for reviewing, nine gave it five stars. Use the machine every day in its first weeks, because a fault found early is the easiest to have fixed.

Jura covers the GIGA 10 for two years or 6,000 drinks

Jura's warranty covers parts and labour for two years or 6,000 drinks, whichever comes first. In Canada, the owner pays the shipping both ways for a warranty repair, and Jura runs service centres in Mississauga, Burnaby and Montréal. In the United States, Jura pays ground shipping to and from its repair facility. Owners reach Jura mostly by phone, and its phone hours are limited. US owners who got through report a replacement drip tray by mail within days, or a repaired machine back in about a week.

In a small office, the GIGA 10 suits about ten regular coffee drinkers

Offices buy the GIGA 10 for the same reasons households do: a decaf option beside regular coffee, and milk drinks from one tap. One company bought a GIGA 10 for a floor of 20 people, about ten of whom drink coffee often, after Jura advised it over a commercial machine built for 100 users a day. Another owner with a GIGA 10 in his office says the coffee is better than Nespresso and that the machine needs regular attention.

The water tank and the drip tray decide how often someone has to look after the machine. One owner counts 8 to 10 small drinks between refilling the 2.6 L tank and emptying the drip tray, and milk drinks fill the tray faster because of the rinses. The GIGA 10 draws water from its tank only, so plan to refill it and empty the tray several times a day, ideally near a sink. For an office making 20 to 30 drinks a day, an owner of two years advises a machine with a larger tank, and another owner puts the GIGA 10's practical limit at about 30 drinks a day. Our guide to the best office coffee machines covers Jura models that can run from a water line.

The warranty counts drinks as well as years. An office making 20 drinks each workday reaches 6,000 drinks in about 14 months, so the warranty ends there instead of at two years. Someone also has to run the milk cleaning each day the office makes milk drinks.

The GIGA 10 suits homes and small offices that drink two different coffees

The GIGA 10 suits a household where people drink different coffees: one person on decaf, a half-caf in the afternoon, or an espresso roast beside a medium roast for long drinks. Each person's drink, milk drinks included, is one tap from the first screen. The GIGA 10 also suits a small office of about ten regular coffee drinkers with a sink nearby.

Jura GIGA 10 vs Z10: the same coffee from one grinder or two

The Jura Z10 makes hot drinks, and cold drinks with Jura's Cold Extraction Process, from one bean container. Owners who have used both machines say the coffee tastes the same. The Z10's grinder changes its fineness for each drink you choose, and it has seven settings. The Z10 sets drink sizes in millilitres or ounces. The Z10 is also smaller, at 36.3 cm tall and 12 kg against the GIGA 10's 41.5 cm and 18 kg, and it has aluminium front panels and a lit water tank.

The GIGA 10 keeps a second coffee loaded and blends the two, switches itself on at a set time, and heats milk on a second heating unit. One owner returned a Z10 because he wanted two bean containers, and used a GIGA 10 for a year. An owner who has a Z10 in one house and a GIGA 10 in another prefers the Z10's look and feel, and says the GIGA 10's drinks are consistent and good once set up. If one coffee suits everyone, the Z10 costs less and makes the same coffee; if your household drinks two coffees, the GIGA 10 keeps both ready.
