Keep your yeast or ML happy and your ferment warm during those cold winter months with this flexible heater made by Fermentap. Using tape to adhere, this flexible heating wrap can be attached directly to your fermenter or can be used to heat the space in a box (or refrigerator) that the fermenter is in. Depending on your configuration and insulation, you can increase the temperature of your wine from 5-20 degress Fahrenheit.

If using carboy or bucket you can attach directly using tape (as seen in photo above.) We recommend electrical tape as it sticks and unsticks the easiest. Heating can be contolled by sticking either the entire wrap or a portion of the wrap to the fermenter. In an open evironment we see a heating differential between carboy and ambient of 10-15 degrees. This differential can be increased by using our carboy bag to insulate a carboy (this has been tested.) To decrease the temperature differential, stick only a portion of the heating wrap to the fermenter.

For precise results, we recommend using our temp controller (FE610) and carboy thermal well (FE612) for the ultimate in fermentation temperature contol.

For heating small stainless variable volume fermenters and barrels up to 30 gallons a single FermWrap! works great. For volumes of 60 gallons or more, we recommend using two or more FermWrap!s (we do this in our winery Olin Wines all the time!).

With 40 watts of heat spread over two square feet it provides gentle even heating. Draws 40 watts. 115V. Manufactured by Fermentap.
