Cask-conditioned beer is unfiltered and unpasteurized beer which is conditioned and served from a cask without additional nitrogen or carbon dioxide pressure. This cask ale may also be referred to as real ale.
What is re-racked beer?
Re-racked beer contains much less yeast and has a very short shelf life - two or three days for a typical cask. It is obtained by decanting, or re-racking, the beer from one cask to another, thus leaving behind the majority of the already residual yeast. The beer in the first cask will (usually) have already been fined, taking the majority of the yeast to the bottom of the cask. Beer should only be re-racked immediately before delivery to the point of service.
What is the process of Fresh/Wet Hopping?
Fresh Hopping is the addition of freshly harvested hops that have not yet been dried to different stages of the brewing process. Fresh Hopping adds unique flavors and aromas to beer that are not normally found when using hops that have been dried and processed as usual.
