I had 3 inches of foaming that spilled out of the primary fermenter air lock last night. This is the 5th day of fermentation and the SG is 1.035 having started at 1.094 when inoculation took place. The yeast that I'm using is Red Star Pasteur Red. I used this yeast exactly a year ago for a Chianti and it gave me no problems according to my wine making log. The Spagnols Cab Shiraz Merlot blend kit was prepared in accordance with directions with the exception of the yeast substitution. Activity in the air lock was seen about 3 hours after inoculation.
The only other time I experienced this level of foaming was with a juice bucket wine that started fermentation with its native yeast before I picked it up. But I don't think that that could be happening with juice from a wine kit so I'm stumped. Pasteur Red is not noted for foaming.
I had planned on adding yeast nutrient today. Although I hesitated due to the foaming, I decided to go ahead with it in the hope that it helps the Pasteur Red overcome any possible native yeast strain.
Fermentation has been slower than usual in my South Florida home throughout the 5 day primary fermentation period. Generally, by the 2nd day activity in the air lock is rapid and by the 5th day, SG readings are 1.005 to 1.010. Air lock activity in this case was steady during the 5 day period with about one bubble per second.
Any thoughts as to the cause of this foaming would be appreciated.
