4-Vinyl Guaiacol Natural 5% in P.G.

Penta Manufacturing Company makes their documentation available in the regions indicated below:

4-Vinyl Guaiacol Natural 5% in P.G. is a vinylphenol, a type of pyranoanthocyanin, diluted in a propylene glycol solution as a solvent. It is produced by enzymatic decarboxylation of the grape compound ferulic acid by certain strains of S. cerevisiae. Vinylphenols can then spontaneously condensate with grape anthocyanins to form pigments important for the color of ageing wine. 4-Vinylguaiacol is also found in beers and is responsible for a pungent clove-like aroma.
