GC2 with Glycol & Cooling Connection Kit

Control and power up to two fermenters at different temperatures and fermentation schedules with the Grainfather GC2. By accurately controlling the temperature of your fermentation, you can produce consistent beers, every time.

When fermentation occurs, it produces heat. But when fermentations get too hot, it can cause the yeast to produce undesirable off-flavours. Therefore, brewers apply cooling to the fermenter so that the yeast has a comfortable and repeatable environment in which to work. Many brewers use fridges for this, but one large fridge per fermenter soon takes up a lot of space.

Glycol chillers are small-footprint refrigeration units that cool a glycol tank to sub-freezing temperatures. This cold glycol can be called upon at any point needed to cool and regulate the temperature of the fermenter.
