Coolship

A Coolship is a traditional brewing vessel designed to allow for spontaneous fermentation, a process that brings complexity and unique flavor characteristics to beer. The Coolship's design promotes natural cooling and exposure to the ambient air, which encourages wild yeast and bacteria to inoculate the wort, leading to fermentation without the need for added yeast strains. This method is most commonly associated with brewing styles such as Belgian Lambics and other sour ales.

One of the defining features of the Coolship is its individual tray design, which maximizes surface area and allows for extended contact with oxygen. This contact with oxygen is crucial for fostering the growth of aerobic bacteria. These bacteria play an important role in the fermentation process by metabolizing ethanol into acetic acid, sugars into lactic acid, and glucose into gluconic acid. These acids contribute to the distinctive tart and sour flavors that are often sought after in spontaneously fermented beers.

The single-wall construction of the Coolship, combined with its large surface area, is designed to naturally regulate the temperature of the wort through exposure to the ambient room temperature. Unlike modern, insulated fermenters, the Coolship relies on its open design to allow the wort to cool gradually. The ability to maintain optimal fermentation temperature through environmental factors is key to producing the subtle and complex flavors that are characteristic of this brewing method.

Each fermenter tray in the Coolship includes a lip around the perimeter, allowing brewers to secure cheesecloth or other screening materials over the tray. This not only prevents debris from entering the wort but also provides some control over the exposure to airborne organisms, while still allowing the necessary interaction with wild yeast and bacteria.

An important aspect of fermentation in a Coolship is the balance of symbiosis between yeast and bacteria. The open nature of the fermentation environment shifts this balance in favor of bacteria, which reduces the overall alcohol production and results in a more intricate flavor profile. By encouraging the growth of lactic acid bacteria and other microorganisms, the Coolship helps create beers with a pronounced acidity and a well-rounded complexity, often described as having earthy, fruity, and funky characteristics.

The ability of the Coolship to influence the balance between yeast and bacteria allows brewers to craft unique beer styles with distinct regional influences. Since the fermentation relies on wild yeast and bacteria present in the environment, each batch of beer can take on different characteristics depending on the location and time of year. This adds a sense of terroir to the brewing process, similar to winemaking, where the environment significantly impacts the final product.
