Description
A bioengineered derivative of BSI's A-56 Chico, modified to release thiols already bound up in malt and hops and so lift passion fruit, guava, grapefruit and blackcurrant well above the base strain. It ferments like Chico and can be repitched; BSI suggest pilsner malt, oats and dextrin malt as precursor sources and advise avoiding wheat and rye.
