Cellar Craft Rosso Fortissimo ((BIG RED) Lot Number C05912SA) I pitched the yeast on 2.10.2010. The average temperature during primary fermentation was (on the low side) 70F. Fermentation in the primary ended on 3.3.2010 (1.000SG) removed grape pack and transferred into a secondary 6 gallon Better Bottle carboy. Transferred most of the lees and left the majority of the French/American sawdust behind using a medium grade nylon filter. In the secondary, I noticed a fairly vigorous fermentation from 3.3.2010 till 3.6.2010. Temperature began to average 64F-66F over the course of the next few days and visible CO2 gas bubbles slowed dramatically. On 3.12.2010 specific gravity was .990 and I stirred the lees into the wine slowly using the drill paddle to ensure the yeast was in suspension. Did not notice any CO2 gas until I added a Brew Belt (which I did not use on the primary) to get the temperature up on 3.15.2010. Now the secondary is rocking and rolling (the wine has expanded an inch and a half up the neck of the carboy). I plan to stir the lees again this Friday 3.19.2010.
My intention for adding the Brew Belt is not necessarily to speed up fermentation (64F seems to low); I want to keep this wine on the lees for at least two months. I just don’t want it to stick before it is as dry as it can be. Cellar Craft Instructions mention keeping the secondary between 66F-75F. The Jack Keller School of thought seems to believe the secondary should be at a lower temp than the primary 60F-65F http://winemaking.jackkeller.net/secondary.asp.
My question is this… now that I have increased the temp of the secondary to 75F, with the Brew Belt, how will this affect the flavor profile of this wine?
Is 60F-65F better during the secondary process?
Also… the Brew Belt is making the wine much warmer on the top of the carboy than on the bottom. Is this OK?
