So What Is Cask Beer Anyways?


We are introducing the Bayou Teche Cask Garden this year and thought we would do a little refresher on what exactly cask ale or cask beer is all about.  Enjoy!

 

What Is Cask Ale?

Cask conditioned ale is beer that is brewed from traditional ingredients and matured in the cask from which it is served. This means that it is fresh and unfiltered and therefore has a unique flavour.

Cask ale is naturally conditioned as a by-product of the secondary fermentation that takes place inside the cask, It is then served directly, without the use of extraneous carbon dioxide or chemical treatments of any sort.

What you are tasting is a live product, full of flavour and character: beer in its natural state.

Cask Conditioned Ale: Extended Definition

Cask conditioned ale, or ‘Real Ale’ is a living beer. It undergoes an important secondary fermentation in the cask (vessel) from which it is to be served.

At the conclusion of primary fermentation, the green beer is racked off into casks, leaving behind most of the yeast. A small amount of yeast is carried over in suspension, which continues to work in the cask. Finings are added to the cask in order to clarify the beer and sometimes priming sugars are added to enhance the secondary fermentation. As well, dry hops are often added to impart a flowery hop note in the finished beer. It is here in the cask that cask ale matures and comes into condition.

Upon arrival at the pub, the cask is allowed to rest, while the yeast continues working and then gradually drops to the belly of the cask as the beer comes into condition over time. Real ale kept at an ideal cellar temperature of 50 to 55 degrees Fahrenheit should clarify within 24 to 48 hours. The cask is vented by means of a wooden spile during this time to allow excess carbon dioxide to escape. The skill of the cellarman, using both soft and hard spiles, manipulates the flow of natural carbonation until the desired level of carbonation is achieved and the beer has matured properly.

Later, the cask is tapped and the beer is delivered to the bar by means of a handpump, the traditional system of dispense.

Real ale develops delicate flavours and does not take kindly to temperature changes and excessive handling. However, when handled properly, cask ale delivers a distinctive, well-rounded taste.
