Another way to read the table above is to list the order in which the precursors are converted into phenol metabolites:
:'''p-Coumaric Acid''' (found in malt and other ingredients) converts to '''4-Vinylphenol''' by POF+ strains of ''Saccharomyces'' and ''Brettanomyces'', which converts to '''4-Ethylphenol''' by ''Brettanomyces''.
:'''Ferulic Acid''' (found in malt and other ingredients) converts to '''4-Vinylguaiacol''' by POF+ strains of ''Saccharomyces'' and ''Brettanomyces'', which converts to '''4-Ethylguaiacol''' by ''Brettanomyces''.
:'''Caffeic Acid ''' (found in malt and other ingredients) converts to '''4-Vinylcatechol''' by POF+ strains of ''Saccharomyces'' and ''Brettanomyces'', which converts to '''4-Ethylcatechol''' by ''Brettanomyces''.
