Cask additives once beer is tapped for longer life?

  1. Hi Is there an additive to add to tapped beer to give it a longer shelf life?


  1. Never heard of an additive but we use a Cask Breather on ours which gives us a week instead of the usual 3 days. It’s basically a non-return valve which releases CO2 when you pull a pint. It will cover the beer with a layer of CO2 thus preventing air getting in. CAMRA don’t like them but they don’t have the expense of throwing away unsold beer.

Do you have a better answer? Leave a reply or an opinion
