What the AI looks for in Growlers

Capacity
64 oz is the standard growler; 32 oz (howler) suits one or two drinkers Breweries fill standard sizes, and unpressurized beer goes flat soon after opening.
Insulation and light
Vacuum-insulated stainless or dark amber glass, never clear glass Light skunks beer, and warmth speeds staleness.
Seal
Gasketed cap or swing top that seals fully A weak seal loses carbonation within hours.
Pressurization
CO2-capable growler if you will drink a fill over several days A standard growler should be finished within a day or two once opened.
Opening size
Wide enough to brush clean Dried beer residue grows mold and gives off-flavors.

Questions

Will any brewery fill my growler?

Rules depend on your region and the brewery: some won't fill growlers with another brewery's logo or that look dirty. Bring it clean and ask.
