Hi guys....had a interesting thing happen during the fermentation of this AG batch I'm doing.
I've read about guys having fermentation's that need a blow off tube. After about 15 or 20 batches, I don't think I've ever been in that situation before. I'm not sure if it is because of the extra head space I normally have in my brews or what, but i've never been in a position to really need one. Normally I have 5 gallons in a 6 gallon carboy.
With that said....I did a batch this weekend where I missed my SG (for silly reason) to go into the fermenter and didn't add the top off water that I would normally done to get to 5 Gallons. It ended up at 4.75 gallons.
This is a very simple American ale with 1056 yeast and 6lb 2-row, 1.75lb flaked corn, 1/2lb flaked rice, and .5lb carapils. Very basic lawnmower beer.
I had .75 lb of carapils left over from previous batch and put that in instead of just .5lb. Also during the boil, I missed putting the whirliflock in at 5 to 10min from end.
This time during the ferment if I didn't have that extra head space I would have needed to put a blowoff tube in.
I'm wondering if the additional proteins from the extra Carapils and missing the whirliflock that the additional proteins caused this huge krausen on the top? It is a fairly good ferment but not overly vigorous but still has a huge head on it.
Anyone else see something similar or have any ideas?
