I recently cold-crashed an English Bitter in a Big Mouth Bubbler using the included airlock cap thing. The one that snaps on and you fill the lid with sanitizer. I hadn’t previously used this device, and it sucked probably a cup of Star-San back into the beer. I’m not going to use this airlock again, but I’d like suggestions for fixing the beer.
It’s sitting on top in a discrete layer, so I think I can rack the beer out from under it. However, I did detect a noticeable tang when I tasted the beer below the layer. The overall flavor is excellent other than that, so I’d like to try to save the batch if possible.
I’m wondering if it would be worth it to try to raise the pH by adding minerals. Anyone have opinions for or against? If so, what type?
