A coolship (Anglicized version of the Dutch/Flemish koelschip) is a type of brewing vessel traditionally used in the production of beer. It is a broad, open-top, flat vessel in which wort cools. The high surface-to-mass ratio allows for more efficient cooling. Contemporary usage includes any open fermentor used in the production of beer, even when using modern mechanical cooling techniques. Traditionally, coolships were constructed of wood, but later were lined with iron or copper for better Beeriodicals. ''A Trademark Battle Averted; It's Cool To Say "Coolship".''

The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by k, \lambda, or \kappa.
Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal ...

The word "coolship" was trademarked by Allagash Brewing Company in the United States. The company later decided to terminate the trademark, in the interests of maintaining good relations with others in the craft beer industry.Retrieved 14 August 2020
Modern use
Coolships are still used in traditional lambic brewing, where the wort is cooled and airborne yeasts and bacteria present in the brewery are allowed to inoculate the beer naturally, in order to create a spontaneous fermentation.References
