A growler is a refillable jug, usually 64oz glass, that customers bring back; a crowler is a single-use 32oz aluminum can sealed on a countertop seamer at the taproom. Crowlers keep beer fresh longer and need no returns, growlers are cheaper per fill for regulars. Cafés selling still cold drinks use a third format: sealed clear PET cans in 4, 8, 12 and 16 oz, all sealed on one countertop machine.
A growler is a refillable to-go container, classically a 64oz glass jug with a screw cap, filled from the tap and carried home. The customer owns the vessel and brings it back for refills.
Strengths: no packaging cost after the first sale and a loyal-regular ritual. Weaknesses: oxygen gets in during an open-air fill, so the contents fade in days once filled and hours once opened, glass breaks, and the shop washes or trusts the customer's washing.
A crowler is a can-sized growler: a single-use 32oz aluminum can filled from the tap and seamed shut on a countertop machine behind the bar. Taprooms adopted them because a seamed can blocks oxygen and light completely.
Strengths: weeks of freshness instead of days, no returns or washing, easy to stack in a fridge. Weaknesses: you buy the cans forever, the seamer is an up-front purchase, and 32oz is a commitment for one person.
| Growler | Crowler | |
|---|---|---|
| Container | 64oz refillable glass jug | 32oz single-use aluminum can |
| Sealed how | Screw cap | Seamed lid on a countertop machine |
| Freshness once filled | Days, then hours after opening | Weeks unopened (carbonated beer) |
| Ongoing cost | Washing and breakage | Cans, roughly $1 to $2 each |
| Equipment | None | Benchtop seamer, typically $3,000 or more |
| Best for | Regulars who refill weekly | Taprooms selling take-home pours |
Neither, in most cases. Crowler seamers are built around carbonated beer in aluminum: 32oz servings, brewery-grade pressure handling, and a can that hides the drink. Café drinks are still, cold, and sold in single servings where the look of the drink is the pitch.
That is the niche the Canned setup fills: a countertop sealer starting at $1,799 that runs clear PET cans in 4, 8, 12 and 16 oz. Same countertop-seamer idea the crowler proved, resized for cold brew, lattes, matcha, and lemonade, with a clear can so the drink sells itself from the grab-and-go fridge.
The range is the point. A crowler forces every pour into 32 ounces; a café picks the size per drink, from a 4 oz espresso shot to a 16 oz cold brew, on one seam standard and one machine. Cans start at 70 cents and the sealed drinks are kept refrigerated like fresh product.
They can physically seal still coffee, but 32oz aluminum is the wrong single-serve format for a café and the machines cost brewery money. A clear can in the size the drink actually sells in, usually 12 or 16 oz, matches how cold coffee moves.
They are built for carbonated product and taproom throughput. Café-grade sealing for still drinks needs less machine, which is why Canned machines start at $1,799 instead of $3,000 and up, and can be split into monthly payments at checkout.
A crowler of beer keeps for weeks because the product is carbonated and stable. A café can of unpasteurized cold brew or matcha is fresh product: refrigerated, dated, and sold within about 3 to 10 days depending on the recipe.
