Getting a new fancy growler for a birthday present. Question - do the growlers with draft taps keep beer fresher longer? (Presumably so you can take some out without exposing the rest.) Does it make a difference? Thanks!
Do you mean the kind that you hand pump/squeeze air into, or the kind that use CO2? If the former, there's no hope of maintaining freshness. If the latter, it's possible, if the growler fill included a CO2 purge.
I have multiple uKeg growlers. The main benefit is maintaining carbonation. Freshness? Probably. but with hoppy beers I'd still fear oxidation. I have purged pre-fill but usually just "cap on foam" and up to 2 weeks seems fine.
