Meraki Gen 2 makes four main changes to the original espresso system: an expanded grinder range with 45 settings, revised brew-group components for 58 mm E61-style portafilter compatibility, a redesigned shower screen and a nine-language interface. In daily use, these changes matter most when you dial in different beans, choose accessories, prepare the coffee bed and navigate the controls. The rotary pump, dual boilers and integrated weighing remain part of the system’s existing foundation.
The changes will not carry equal weight in every kitchen. Someone who uses one familiar espresso blend may notice accessory choice more than the additional grind range. Someone regularly buying different coffees may have the opposite priority. The useful question is where each refinement meets something you actually do.
When You Open a Different Bag of Coffee
A new bag can require a different grind setting even when your preferred dose and beverage weight stay the same. Roast style, coffee age and the characteristics of the beans all influence how a recipe behaves.
Gen 2 expands the adjustment range to 45 settings, adding ten coarser and five finer positions. This gives you more range to work within when establishing a recipe for another coffee.
That distinction matters: a wider range does not, by itself, tell you the distance between every pair of settings or guarantee that a particular coffee will need fewer attempts. The practical benefit is having additional positions available, especially when your previous adjustment was approaching one end of the range.
Suppose you bring home a lighter espresso roast from a local roaster. Start with the roaster’s suggested dose and beverage weight if they suit your basket. Then adjust the grind according to the machine’s instructions while keeping your preparation consistent. A grind number from another machine is not a transferable recipe.
The same applies when moving from Gen 1 to Gen 2. Re-establish the setting by observing the extraction and tasting the result rather than assuming that an identical number produces an identical grind.
Who is most likely to value this change? Someone who regularly changes coffees or finds that a preferred recipe needs adjustment beyond the available range. If your usual blend already works comfortably on your existing machine, the extra positions may be less significant.
When You Want to Keep or Change a Portafilter
A portafilter is something you handle for every shot. Its fit affects loading, locking into the group and removing the used coffee afterwards. It also determines which accessories you can sensibly consider.
For Gen 2, Meraki revised the brew-group components with a split-rail structure and 58 mm E61-style portafilter compatibility. This broadens the potential choice of compatible handles. The locking mechanism was also refined, making the physical interaction part of the update.
E61-style portafilter compatibility describes the fitting; it does not mean Meraki uses a traditional E61 brew group. Nor does the number “58 mm” establish that every handle or basket will fit.
Before transferring an accessory from another setup, check:
- Whether the portafilter manufacturer explicitly lists Meraki Gen 2 compatibility.
- Whether the locking ears, body and basket depth match the machine.
- Whether the basket suits the intended dose and provides appropriate clearance.
- Whether your tamper, funnel and puck screen fit the basket you will actually use.
Meraki’s own 58 mm bottomless portafilter has separate Gen 1 and Gen 2 compatibility options. That is a useful reminder to select by machine generation as well as nominal diameter.
Who is most likely to value this change? Someone who wants a particular compatible portafilter or plans to develop their accessory setup. If you prefer the supplied equipment and have no reason to replace it, broader compatibility may remain a future option rather than an immediate benefit.
When Water Reaches the Coffee Bed
The shower screen sits above the basket and distributes brewing water towards the coffee. It is less visible than the touchscreen or grinder dial, but it is involved in every extraction.
Gen 2 introduces a revised shower screen with two-stage diffusion, designed to disperse incoming water before it reaches the coffee bed. The purpose is to support more even wetting.
This is a change to water delivery, not a substitute for preparing the grounds carefully. An unevenly filled basket, an unsuitable dose or a poorly distributed puck can still produce uneven extraction.
It is also difficult to attribute a better-tasting shot to the screen alone if you change the coffee, basket and recipe at the same time. For a meaningful comparison, keep those factors consistent and assess several preparations rather than one unusually good cup.
During everyday use, the useful habits remain simple: distribute the grounds evenly, tamp level, keep the basket rim clean and maintain the screen according to the operating instructions. The hardware and the preparation need to work together.
Who is most likely to value this change? Anyone interested in the details of water distribution. Its contribution is less immediately visible than extra grinder positions, and it should not be presented as a guarantee that channeling will disappear.
When Someone Else Uses the Machine
A shared coffee machine needs controls that everyone using it can understand. Reading a dose, checking a brewing setting or responding to a maintenance message can become unnecessarily difficult when the interface language is unfamiliar.
The Gen 2 announcement lists nine interface languages: English, German, Spanish, Polish, Arabic, Simplified Chinese, Traditional Chinese, Japanese and Korean.
What Still Supports Your Espresso and Milk Routine?
It is easy to mix generation changes with the reasons for choosing the overall machine. Meraki’s rotary pump, dual boilers and integrated dose-and-yield weighing belong to the system’s established architecture.
If you make cappuccinos or flat whites, the ability to brew and steam together remains relevant. It should be understood as part of the machine’s milk-drink workflow rather than a feature introduced by these Gen 2 revisions. The choice between sequential preparation and brewing while steaming milk still depends on your confidence and the drinks you are making.
Your choice of beans remains separate from the generation comparison, too. CoffeeSense supplies recipe guidance from compatible tagged bags, while ordinary beans require your own starting settings. Understanding how your own beans work with CoffeeSense and manual settings is useful whichever part of the Gen 2 update interests you.
These distinctions help you assess the machine without counting the same advantage twice: first as a reason to choose Meraki, then again as a reason to replace an earlier Meraki.
For Gen 1 Owners, Identify the Limit Before Replacing the Machine
Start with a specific observation about your current setup. Perhaps a coffee you regularly buy needs more grind range. Perhaps the portafilter you want is not compatible. Or someone in the household would benefit from an added interface language.
Those are concrete reasons to investigate Gen 2. A general hope that a newer machine will automatically make every cup sweeter is harder to assess.
| Your current situation | Relevant Gen 2 change | What to check first |
|---|---|---|
| A regular coffee takes you towards the end of your grinder’s range. | Additional finer and coarser settings. | Confirm that dose, basket condition and preparation are appropriate. |
| You want a different portafilter. | Revised E61-style compatibility. | Obtain explicit compatibility confirmation for the exact accessory. |
| Someone finds the existing interface language difficult. | Nine-language interface. | Check that their preferred language is included. |
| You already enjoy repeatable espresso with your usual equipment. | The refinements may have less immediate relevance. | Identify a practical benefit you would use regularly. |
For a first-time buyer, assess the complete Meraki Gen 2 espresso system against your drinks, available space and willingness to prepare coffee by hand. If you are still deciding what type of machine fits, the starting point is the difference between espresso and filter brewing, before individual generation details.
Gen 2’s changes are easiest to understand at the points where you meet them: adjusting a new bag, choosing a handle, preparing a shot and reading the controls. Decide which of those moments needs improvement in your kitchen, then judge the update against that need.
