Also known by the brand name Star-San, Phosphoric Sanitiser is the most effective and fast acting sanitiser product available. It foams up during use however it is a no-rinse sanitiser and left over foam will break down and become a yeast nutrient. This is THE sanitiser we recommend for all brewers. Used as a no rinse it does not contaminate or add any off flavour to the brew.
This is a highly concentrated sanitiser and one bottle should be enough to sanitise a keg or fermenter hundreds of times.
