Anchor Brewing (San Francisco, CA) will soon introduce the seventh edition in the Zymaster Series soon.
The series, which debuted with California Lager, is a brewer driven series where the brewmaster researches, creates, and brings to fruition, a unique new offering for the brewery.
Potrero Hill Sour Mash IPA follows #6, Saareemaa Pale Ale.
Presumably, Sour Mash IPA is brewed a bit like a berliner weisse, where the brewer allows the mash to naturally sour in the tun for a day/days then completing the brewing process.
As with the previous offerings, Anchor Potrero Hill Sour Mash IPA will be available in 22oz bottles, and draft.
Availability: 22oz Bottles, Draft.
