I brewed a batch of AK47 Pale Mild Ale on Friday, December 30 using Windsor Ale dry yeast. Fermentation began very quickly and vigorously but today has already slowed considerably (airlock bubbles once every 3 minutes). The specific gravity has dropped from 1.040 to 1.010. The temperature of the bucket fermenter is approximately 67 degrees. Could fermentation be near completion already? This is only my 6th batch, and I’ve never had fermentation slow so quickly.
