Carbonation help wanted!
I just switched over to 5.7 unitanks (from my 1/2 barrel nano fermenters). I had previously crashed, carbonated and bottled from the smaller tanks, and had my product precisely where I wanted it. It had a nice, thick head and good retention. When I switched over to the unitanks, I placed about 4.2 barrels of product into the new tank (all that I had on hand), crashed it, and carbonated it to (what should have been) the same 3.0 + volumes of CO2, based on the temperature and pressure. For the small vessels, I was filling them, crashing them, then putting on the gas and rocking them. The new vessels have a carbonation stone, located just above the point where the cylindrical and conical portions of the tank meet. I had the tank chilled to 34 degrees, and had 15 psi on the stone. (It was there for a couple of weeks, because I still had other things to get in place before I was ready to bottle.) While bottling, everything looked "normal." The product appeared to have plenty of gas. However, when I open one, I get about half of the head that I had with the batches I carbonated in my smaller tanks. It is not thick, lacy and creamy like the previous batches, and disappears quickly. Is this because my tank had too much head space? Thankfully, I only bottled about 1.3 barrels. I want to salvage what I have left. I am thinking of transferring it to smaller tanks and repeating what I had done before. I'm a little bummed right now.
