Stainless Steel - advantages • Easy to maintain • No need for a liner • Unlimited choice of cleaners/sterilizers • Easy automatic handling • Either fabricated or deep drawn • Availability – 1 UK, 1 French, 1 Spanish & 2 Chinese suppliers.
Stainless Steel - disadvantages • Weight for large containers • Denting & chime damage • Repair costs – need for outside specialist • Theft
Plastic - advantages • Price • BP stackable • Light weight • No scrap value • Colour coding
Plastic - disadvantages • Supply – only BP & Emmerald • Quality – splits/breakages/distortion • Specification – volume/hole sizes • Sealability – variation in shive bush size • Weight – too light for large volume brewery washers/auto tilt devices • Strength – squashed by large volume brewery rackers & fork trucks
Closure Selection? • Wood – shive, keystone, tut & spile (peg) • Plastic – shive, keystone, tut, spile & tap hole bung • Cork – tut & tap hole bung
Wood - advantages • Natural product • Swells when wet • Spile – porous to allow CO2 to escape, hard to seal but when loose to allow O2 ingress
Wood - disadvantages • Pieces in cask often not removed by washing therefore needing to be removed by hand • Keystone breakage on tapping • Shive breakage on removal • Potential infection of beer from debris or contaminated spiles • Microbiological issues (mould/flies) • Price
Plastic - advantages • Price • Sterility • Only small pieces fall into the cask easliy removed by washing process • Can use colour to denote quality/brand • Can print/mould for branding
Plastic - disadvantages • Leaking – do not swell to take neck discrepancies therefore a need for various sizes • Leaking – highly conditioned beers in high ambient temperatures (normally keystones)
Cork • Used as tap hole bung • Used as tut hole bung • Alternatives are a plastic tap hole bung (UB) & either the spile or plastic tut to seal shive
