Where These Terms Actually Come From
Both terms feel informal and interchangeable on a taproom chalkboard, but they have real definitions worth understanding — especially if you care about where your beer comes from and how it's made.
The word craft beer is defined and promoted by the Brewers Association, a nonprofit trade group that represents small and independent U.S. brewers. According to their framework, a craft brewery must meet three criteria: it must be small (producing no more than 6 million barrels of beer per year), independent (less than 25% owned by a non-craft alcohol industry member), and traditional (using conventional ingredients and fermentation processes, not flavor additives that mask the malt base).
Microbrewed beer, by contrast, is defined purely by production volume. A microbrewery produces fewer than 15,000 barrels annually. The term emerged in the 1970s and 1980s to distinguish small-batch producers from the large commercial breweries that dominated the American market. It says nothing specific about ownership or ingredient sourcing.
A Note on Marketing Language
Neither 'craft' nor 'micro' is a legally protected term in the United States. Any brewery can use these words on packaging without meeting industry-defined criteria. The Brewers Association's independent craft brewer seal is one of the few voluntary markers that signals verified compliance with their standards. When in doubt, look up the brewery directly.
These distinctions matter most when reading packaging and marketing. A large conglomerate-owned brand can use language that evokes small-batch brewing without technically qualifying as a craft brewery under industry definitions.
How They Overlap — and Where They Diverge
The confusion is understandable: the overlap is genuine. A microbrewery that is independently owned and uses traditional ingredients is, by definition, also a craft brewery. Most microbreweries comfortably fit both labels.
The divergence appears at scale. A brewery that started as a microbrewery and grew — say, to 100,000 barrels per year — would no longer qualify as a micro by volume, but could still be a craft brewery if it remains independent and ingredient-honest. Boston Beer Company, producer of Samuel Adams, is a well-known example of a large craft brewery that long exceeded microbrewery production thresholds while still meeting the Brewers Association's craft criteria.
| Criterion | Craft Beer | Microbrewed Beer |
|---|---|---|
| Defined by | Size, independence, and ingredients | Production volume only |
| Annual production cap | 6 million barrels | 15,000 barrels |
| Independence requirement | Yes — less than 25% corporate ownership | No formal requirement |
| Ingredient standards | Traditional ingredients required | No ingredient standard |
| Governed by | Brewers Association criteria | TTB licensing category |
| Can overlap? | Yes — most microbreweries qualify | Yes — if also independent and traditional |
The reverse is also possible but rarer: a small-volume brewery with significant corporate investment might technically be a microbrewery by output but not qualify as craft under the independence rule. This gray area is where careful label-reading pays off.
Why the Distinction Matters at the Bar or Bottle Shop
For most casual drinkers, the practical takeaway is this: both terms signal a departure from mass-market, industrial brewing — but they signal it in different ways. Micro is about scale; craft is about identity.

Craft breweries operating in the U.S.
According to the Brewers Association, the number of operating craft breweries in the United States has grown dramatically since the 1980s, reflecting sustained consumer demand for independent beer.
13%
U.S. beer market volume held by craft
The Brewers Association has reported that craft beer accounts for roughly 13% of total U.S. beer volume, a significant share given that thousands of small producers compete against a handful of global conglomerates.
When you see "craft" on a tap handle or label, it theoretically carries a promise of independent ownership and thoughtful ingredients. When you see "micro," it tells you the operation is small, but doesn't guarantee who owns it or what went into the recipe.
The marketing reality is messier. Large alcohol companies have launched brands designed to look craft — small fonts, vintage illustration, local-sounding names — without meeting the Brewers Association's independence standard. This practice is sometimes called craftwashing. The best defense is to look up the brewery directly or check resources like the Brewers Association's independent craft brewer seal, a small, voluntary certification mark some qualifying breweries display on their packaging.
Neither term is a guarantee of flavor or quality on its own. A microbrewed lager can be mediocre; a craft IPA can be extraordinary. But understanding these definitions helps you ask better questions and make choices that align with your values — whether that's supporting local economies, seeking out traditional brewing methods, or simply finding a beer worth savoring.
