What You Need to Know
In the brewery industry liquor is a term used to refer to water for use in the brewing process. A Cold Liquor Tank is therefore a tank filled with cold process water as seen in breweries. These tanks are often needed because breweries operate as Batch production processes rather than Continuous production processes. This means the production rates of water (liquor) are often insufficient for the point loading requirements of the processes. Cold liquor tanks are used as buffer storage for this purpose such that water production rates are sufficient on average.
