Turbo yeast
Turbo yeast is a mix of dry wine yeast (Saccharomyces Cerivisae) and nutrition. The particular strain used (there are many different strains of Saccharomyces Cerivisae) is chosen for its ability to produce alcohol and the nutrients are optimised for providing exactly the right combination of nitrogen, vitamins and trace minerals which the yeast needs in the different stages of alcohol fermentation. It also contains a pH adjustment as the pH of a sugar/water mix is far from optimal.
