Notes

Bottle conditioned - strong flocculation helps with clean pours.
Carbonation completed in just a few days @ 68F.
Thick layer of yeast in each bottle suggests a possibly over-pitched batch.

Added 01/04/2020:
The Riverfish Team has just learned that incorrect use of the pitching calculator has lead to heavy over pitching. Essentially, cell counts in a pack of dry yeast was grossly under estimated. However, this batch used Imperial liquid packs.
