Description PHOSPHORIC ACID 75% is a clear solution made from food grade phosphoric acid and is used in the brewing industry for acid washing yeast. Principle Acid washing is a tool that brewers use to eliminate contamination bacteria from pitching yeast. Acid washing kills bacteria with minimal harm to the brewing yeast, providing that the process is carried out correctly. The effectiveness of the process relates to the time and temperature it is carried out, at and the pH achieved. NOTE: Acid Washing will not remove wild yeast. Method of use Preparation is essential. Ensure that you have the yeast and the acid fully chilled as the wort day when you are not brewing. Viability of washed yeast will fall markedly as storage time increases.
