Westerham Brewery

Why it matters

One of the clearest demonstrations that a house yeast is a brewery asset rather than a commodity: the strain was retrieved from the National Collection of Yeast Cultures decades after the original brewery closed.

Details

Styles it is associated with

• Best bitter — A step up from ordinary bitter in strength and depth, with more malt body while staying firmly sessionable.

Traditions

• British cask ale — Beer that completes its fermentation in the container it is served from and is dispensed without added gas, at cellar rather than fridge temperature.
