I don’t know but:
If I bring a 7/8ths full beer back to the bartender-Fremont’s Field to Ferment, in this instance-and say “I don’t want this, it’s got an awful, dirty taste on the back end and can’t drink it.”
and the bartender samples the beer and says “I can see where you’re coming from.”
Then I believe the response should be to offer me a replacement, not the opportunity to purchase another beer.
Grrr.
A good reason to avoid the place in the future.
