[Taste/Aroma] Dry like tea [Adulterant] Grape tannin [Amount Added] 5 tsp of tannin solution (1/4 tsp grape tannin powder in 5 TBSP water) in 24 oz of base beer [How Created] Created by mash pH rising too high, which pulls tannins from the grain husks. This is usually due to over-sparging. [Flavor]
