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 both ''Saccharomyces'' and ''Brettanomyces'', which converts to '''4-Ethylphenol''' by ''Brettanomyces''.
'''Ferulic Acid''' (found in malt and other ingredients) converts to '''4-Vinylguaiacol''' by both ''Saccharomyces'' and ''Brettanomyces'', which converts to '''4-Ethylguaiacol''' by ''Brettanomyces''.
'''Caffeic Acid ''' (found in malt and other ingredients) converts to '''4-Vinylcatechol''' by both ''Saccharomyces'' and ''Brettanomyces'', which converts to '''4-Ethylcatechol''' by ''Brettanomyces''.
