Hello everyone,
Last weekend, we brewed 40 litres of a farmhouse type beer. 20 litres went into a glass carboy and the other 20 litres went into another identical glass carboy. In each we pitched 1 vial of WLP670 American Farmhouse blend from White Labs (http://www.whitelabs.com/yeast/wlp670-american-farmhouse-blend). We ferment in a freezer with a temp controller at 21C/~70F. Each carboy is rigged with a tube thus creating a blow off (the other end of the tube ends in a 1 gallon water filled jug). OG of the beer was 1.060 /*14.7 Plato.
After 12 hours, the fermentation was going top notch. Good esters were coming from the carboys. Bubbling, activity, movement, everything norma (I’ve been brewing with this "method" for ~2 years). After 48 hours, fermentation was still going A1. See picture 01.jpg.
After 72 hours, one of the carboy seemed to be "dead". No more foam head. No more bubbles coming from the end of tube. Almost no activity/movement in the carboy (see pictures 02 and 03.jpg).
Anyone ever had this or something similar happening to them? What should I do? Should I try and restart the fermentation? Should I measure the gravity to see what happened? Thanks.
