Tips & Tidbits
Warm Weather Fermentation Tricks
The excessive heat this summer has provided some challenges for wine makers and brewers. Here are a few tips which can assist in reducing the temperature of your fermentation without having a temperature controlled fridge:
§ Covering your fermentation vessel with a wet towel will reduce the temperature about 5°F;
§ By placing the end of the towel in a bucket of water, or even better, put the fermentation vessel in shallow water, the towel will wick the water up never drying out maintaining the temperature reduction;
§ Another method of keeping the towel wet, is like drip irrigation with a hose dripping on the towel from above keeping it wet. If using this method, make sure the fermentation vessel is in a container to catch excess water which may drip from the towel;
§ The temperature may be reduced another 5°F by setting up a fan to blow on the towel; or
§ Place the fermentation vessel in a vessel large enough to fill with water up to the liquid level in the fermentor and put milk jugs which have been filled with water and frozen in the water along side the fermentor. Change the milk jugs with freshly frozen jugs as they water begins to melt.
If your goal is to produce high ester levels in wheat beers, farmhouse ales and saisons, enjoy the heat.
