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 16oz clear PET cans.
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 $1,799 countertop sealer for 16oz clear PET cans. 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. Cans cost 99 cents each in cases of 100 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 16oz clear can matches how cold coffee actually sells.
They are built for carbonated product and taproom throughput. Café-grade sealing for still drinks needs less machine, which is why the Canned sealer costs $1,799 instead of $3,000 and up.
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.
The $1,799 countertop sealer ships free. Add a case of blank cans and start the day it lands.
