I made a Winter Warmer and its been in the bottle since 11/14/09, and it is fully carbonated; however the head goes away immediately and is more reminiscent (and sounds like) the fizz from a pop (or coke or soda depending on where you live). I even used fancy one way bottles obtained from my LHBS. 7.6 ABV
It was an extract recipe. 6# Light LME and 2# Corn Sugar, 1/2 # Roasted Barley steeping grains and 2 oz challenger hops (6o min). It was a partial boil, and I did not do a late LME addition. The following spices were added to the boil and boiled for 15 minutes: 1/2 t nutmeg, 1/4 t ground cloves, 1/2 T ground cinnamon. 1 t of plain supermarket brand vanilla extract was added at flameout.
The yeast was Muntons Gold. I mixed and aerated the dry yeast instead of sprinkling atop the wort per the instructions. Nor did I rehydrate. 13 days in Primary and then bottled, no secondary. The beer was kinda cloudy when i bottled it and I expected more trub in the bottom.
Why is my head fizzing away? are any of the spices I put in it a "head" killer? Should I have not aerated and mixed the wort after pitching the yeast?
(it should be noted I made an ESB later in Dec, and used the same Munton's Gold yeast but sprinkled it atop the wort after aeration and did not mix it in --- the head on that beer is outstanding..its creamy and 2 inches thick w/ lacing --- I admire it for a minute before I drink )
