Perfect pint

Ascorbic Acid can help make a perfect pint

BENEFITS

  • Is an economically effective anti-oxidant
  • Reduces the susceptibility of beer to oxidation haze
  • Increases the shelf-life of pasteurised and non pasteurised beers
  • Prevents “papery” (oxidation) off flavours in the final product

Application:
Solutions of ASCORBIC ACID should always be freshly prepared and treated into the bulk of the beer without delay, if possible metering into the flow of beer to tank. Anti-oxidant treatment is more efficient when added before the beer has had contact with air, i.e. as soon as practica-ble after fermentation. Addition of the material prior to cold storage is common practice, in which case the anti-oxidant should be added when the tank is almost full to minimise contact with air.

‘I have found Zetolite to be a fast and effective way of removing H2S from beer. It is a useful stock item to have as a back up when the usual process controls adopted to regulate H2S levels have not been successful.’ .
