Last stage in the beer process Fining Fining agents are added to UK cask beer to ensure they drop bright prior to serving. There are two routinely used variants of finings, white and auxiliary. Each time the beer is disturbed and then allowed to settle (re-fined) the action becomes less effective and after 7 or 8 actions will no longer fully perform.
Isinglass white Finings From fishes swim bladders These fish are farmed in tropical and sub tropical countries in SE Asia Nile perch (Lates niloticus)
How does it work? Isinglass from the swim bladder is refined and added to the beer Live and dead yeast cells And NMPs (non molecular Proteins) Isinglass adheres to Live yeast cells only Isinglass/yeast cell flocs settle leaving dead yeast and NMPs in suspension
Auxiliary finings So now comes the action of the silicated auxiliary finings to finish the job Auxiliary finings loads all positive and neutral Particles with a negative charge All beer particles now rendered available for Isinglass interaction The combined flocs settle entrapping any unreacted Particles more efficiently
Cask Sizes and Fabrication Three sizes regularly used in The UK from left to right Firkin (9 gallons 40lts) Kilderkin (18 gallons 80 lts) Barrel (36 gallons 160 lts)
Manufacture Components are pressed and fabricated from 304 stainless steel. Sections of steel coil are cut then formed on a press and trimmed for the two halves
Manufacture Ancillary parts are made Chimes Keystones Shives
Manufacture Bringing the components together Components are assembled and A second jig in a water bath welded on a jig checks bung orientation and container integrity
Manufacture Fabricated casks are checked for contents and strength Casks are filled with water and Lifted to a set height at a set angle. They are then dropped on to a steel Plate and the resulting distortion to The chime measured as well as the Seams being checked for leakage.
Manufacture Contents checks are carried out then the casks are pickled prior to painting.
Manufacture Finished casks ready for delivery Note the colour banding on The casks to aid repatriation To the owning brewery. In this case Oxford and Cambridge Blue which is the registered Band colours for Wells and Youngs
of Palletisation at the end packaging Note layer pads Format Needs a clamp truck Size selected by layer for stability
Cool store and primary distribution With cask conditioned beer being a live and unpasteurised product, cool storage throughout the supply chain is most important. Temperature should be around 12 C or 55 F to both keep the beer fresh and allow fining to work.
Secondary Distribution From the primary warehouse casks are delivered to the pubs and clubs on smaller lorries known as Drays. Most are not refrigerated due to the lower ambient temperatures in the UK but it is important that these vehicles are not loaded for too long before going on delivery routes.
The Pub Cellar and Cask Beer In the cask beer journey the pub cellar is one of the most important stages between grain and glass. - Temperature stabilisation at a target of 55 F - Settling and venting for normally 48 hours - Hygiene cellar and lines spotless - Hard spile the cask after venting and between sessions to keep in condition (carbonation) - Try your beers prior to serve, know how they should be
The Pub Cellar and Cask Beer Casks lined up on stillage ready to Serve auto tilts Can be seen which Will raise the rear of the cask as it empties To ensure all beer is Extracted.
Cask to Bar Hand Pull Arrangement of hand pulls And counter mounts is now Quite well defined in most Retail operations. Note the hybrid Bombardier Font. The three hand pulls tend to be known as the wickets and The best stump is the left end
Cask to Bar Hand Pull It is important that the installation Is tailored for the needs of cask beer And the bar staff Gas assist pumps Correct temperatures Separate coolers Line insulation pythons Easy to clean
Separate cooler Clean, Clean and more clean, cellar, pipes and glasses. Temperature control, separate python to get beer to the glass at 10 15 C. Sparklers on beers which require a creamy head and a softening of the hop character. Branded glasses pints and ½s.
Insulation right up to the hand pull Beer pipes coming in under The bar are fully insulated As is the actual cylinder on the beer engine.
Hand pump Note what is above and Below the bar. Both beer and cooling water Connections on the pump cylinder.
Hand Pump and Pour Appearance in the Glass and flavour Intensity can be influenced By the use of a Sparkler. This is a plastic cap with fine holes through Which the beer is Forced by the pumping Giving agitation and aeration
