Pretty In Pink

Pitching Yeast

Quite fitting for Valentine's day is a pretty in pink fermentation chamber the barrel box. The project is approaching final gravity within a week. The starter culture of Lactobacillus Delbrueckii was given 4 days of heated fermentation at 120F. The first sign of pellicle appeared within 24 hours. After the lag phase the gravity dropped 64% by day four. The flavor is tart with light notes of oak. There is very little acid in this Berliner. The fermentation is very clean. I've pulled a sample contemplating if the acid will increase overtime. I like the clean lactic acid as opposed to the sharp acetic acid from acetobacter. Overall I will say our work is paying off.
