Symprove is made in a controlled environment through a series of carefully controlled stages. First we boil specially selected grain to create a wort. The wort is purified and sterilised and following this, the temperature is controlled in sterilised vats and the four strains of bacteria are carefully introduced. The live bacteria begin to divide and once the required levels are reached, the process is halted and Symprove is ready for bottling once it’s been tested by an independent laboratory. Throughout every stage, the bacteria are carefully nurtured as they are living organisms. The bacteria we use are high purity laboratory cultures which are unique to Symprove.
