“Designed and manufactured in Portland, OR these growlers are slip cast by hand with the necks carefully trimmed on the potters’ wheel for the tightest of lid fit. They’re cast thick to hold in the cold for all of your 64 ounces. The wide mouth ceramic flip top lid with rubber gasket will seal carbonation keeping your liquids, whatever they may be, cold and crisp for days.”
Rare Barrel uses these growlers from Portland (32 oz.) and they have had wide spread leakage problems.
