Our Mobile Coolship


What is a Coolship?

A Coolship (or koelschip) is a traditional, flat, open topped cooling vessel used by the brewers of yesteryear. Designed to cool down wort (unfermented beer) whilst also capturing micro-organisms (including yeast) in the air – coolships allow for the spontaneous fermentation of beer.

The barrel aging. The beer.

This wild-yeast and wort mixture is then taken back to The Barrel Project and transferred to our French oak wine barrels where it ferments and matures for anywhere between one and three years. Here it undergoes a slow fermentation and souring process before being blended and packaged. This allows the yeast ample time to chew through complex sugars – creating a myriad of flavours and aromas, and ultimately a unique, exceptional beer.

The crowdfund

We want to thank all who made this adventure possible – without them the coolship would have never sailed.
