Found out that the sour taste was from using lactic acid to lower my ph in my mash due to my very hard water. I will never use lactic acid for lowering ph again. 4 batches tainted.
Tasted after 1 week of aging in bottles. It may have an infection. I can detect a hint of malt vinegar smell. This beer is light in color and taste so there is no hiding the vinegar nose. Carbonation is good. Head retention is average. I will try another sample in 2 more weeks.
