Meraki Gen 2 keeps the original machine's architecture and refines it where home users feel the limits: a wider grind range, standard 58 mm portafilter compatibility, a redesigned shower screen, and more interface languages. For first-time buyers the answer is straightforward, start with Gen 2; for Gen 1 owners the upgrade decision depends on how much those refinements matter to your daily routine.
What Meraki changed in Gen 2
The official change list is precise. The grinder gained ten coarser and five finer settings for a total of 45 grind settings, aimed at light roasts and finer adjustments. The portafilter system is now compatible with standard 58 mm E61-style portafilters, opening the door to the wider accessory ecosystem. The shower screen was redesigned with two-stage diffusion for more even saturation. And the operating system now supports nine languages, English, German, Spanish, Polish, Arabic, Simplified Chinese, Traditional Chinese, Japanese, and Korean. The Gen 2 announcement is the authoritative source for these changes.
The change list is deliberately conservative: no new boiler architecture, no new pump, no redesign of the workflow that owners already knew. That restraint is a feature, because it means Gen 2 improves the machine without asking owners to relearn it. The refinements target the two complaints most likely to surface in owner communities, grind range for light roasts and accessory compatibility, rather than adding features nobody asked for.
The nine-language interface deserves its own note: for a global brand selling into Europe, the Middle East, and Asia, the localized UI removes a real barrier for non-English speakers. It is the kind of change that does not show in a spec comparison but shows in daily use for a large share of buyers.
Grind range: 45 settings per official specifications
The practical effect of the 45-setting range is visible in dialing. On the original machine, light roasts sometimes sat between settings; on Gen 2, the extra finer settings give light-roast drinkers a real adjustment path without jumping past the window. The number is official: the specifications on the product page list 45 grind settings, and the Gen 2 announcement explains that ten coarser and five finer settings were added. The range is not a marketing number; it translates directly into fewer "in between" positions, and the grind size guide explains the dialing method the settings support.
The practical effect is also visible in the shot: a grind that lands between settings produces shots that alternate between sour and bitter, while a grind that lands produces shots you can judge by taste alone. That is the difference a wider range makes in daily use, and it is why dialing in on Gen 2 starts from an official 45-position scale rather than an arbitrary guess.
The 45 settings are not equally spaced; the finer end carries the extra resolution, which is exactly where light roasts live. That distribution choice, more positions where dialing is hardest, is the practical reason the range matters. For a light-roast drinker, the difference between two settings that both miss and one setting that lands is the entire dialing experience.
E61 portafilter compatibility explained
E61-style compatibility means the machine uses the industry-standard 58 mm portafilter size and basket ecosystem, so tools from other machines, baskets, and accessories work with it. It does not mean the machine uses an E61 group; it means the portafilter standard is shared. That distinction matters for buyers who already own baskets or plan to upgrade accessories later. The full explanation of portafilter sizes and the 58 mm ecosystem is in our portafilter and basket guide.
The compatibility also protects the purchase over time: baskets wear, tampers get upgraded, and a standard size means replacements are available everywhere rather than only from the manufacturer. For buyers who plan to keep a machine for years, that ecosystem access is a quiet form of future-proofing.
Should Gen 1 owners upgrade?
Upgrade if light roasts are a regular part of your routine, if you already own 58 mm baskets or want that flexibility, or if the extra interface languages matter to someone in the household. Hold off if your Gen 1 machine is dialed in and you rarely change beans, because the core hardware, boilers, pump, and scales, is unchanged. The upgrade is about range and ecosystem, not about fixing a flaw.
A practical test: pull the same bean on both machines and see whether the original grinder lands on a usable setting. If it does, the upgrade is optional; if the bean sits between settings, Gen 2's finer steps are the answer. The same logic applies to the portafilter question, whether you already own 58 mm tools.
Should new buyers start with Gen 2?
Yes. There is no reason for a new buyer to seek out the original machine: Gen 2 costs the same class of money, keeps everything that worked, and adds the refinements above. Buying Gen 1 to save a little is false economy if the finer grind range or portafilter compatibility matters to you later.
The only reason to consider Gen 1 is price, and the savings rarely justify losing the grind range and ecosystem access. Dealers occasionally discount older stock, but the long-term value of the refinements outweighs the short-term saving.
The verdict
Gen 2 is the machine the brand should have shipped first: the original proved the architecture, and this version closes the gaps that home users actually hit. Gen 1 owners with light-roast habits or accessory plans should upgrade; everyone else can stay put. New buyers should choose Gen 2 without hesitation. The verdict also depends on warranty and service timing: a Gen 1 machine still under warranty is worth keeping, while a machine near the end of its service life is a natural upgrade point.

Questions Buyers Ask About Meraki Gen 2 vs Gen 1
Is Meraki Gen 2 worth upgrading from Gen 1?
Only if you regularly dial in light roasts, want 58 mm portafilter compatibility, or need more interface languages. The boilers, pump, and scales are unchanged between generations, so Gen 1 owners with a dialed-in routine will not notice a difference in daily espresso. The refinements are real, but they serve specific needs.
Run the math on your bean habits: if most of your shots come from medium-dark blends, the original grinder range probably serves you fine.
Do Gen 1 accessories work with Gen 2?
Portafilter and basket compatibility improved in Gen 2 with the 58 mm E61-style standard, so the accessory ecosystem is wider than on Gen 1. If you already own 58 mm baskets or tampers, they are more likely to work with Gen 2 than with the original.
Because the group and portafilter standard changed, check compatibility per accessory rather than assuming the whole kit transfers.
The 58 mm standard also means future purchases, baskets and tampers included, are easier to find, which matters for a machine you plan to keep for years.
Which languages does the Gen 2 interface support?
Nine: English, German, Spanish, Polish, Arabic, Simplified Chinese, Traditional Chinese, Japanese, and Korean. The list is from the official Gen 2 announcement and may grow with future updates.
