    Dropping down the left side:

    • Methanoate - Formate - Formic Acid Esters - Not commonly found in distilling.
    • Ethanoate - Acetate - Acetic Acid Esters - Bacterial - Produced by a number of different bacteria
    • Propanoate - Propionate - Propionic Acid Esters - Bacterial - Produced by Clostridium and Propionibacterium
    • Butanoate - Butyrate - Butyric Acid Esters - Bacterial - Produced by Clostridium
    • Pentanoate - Valerate - Valeric Acid Esters - Bacterial - More common are the iso-Valerate esters - produced by Brettanomyces.

    A number of the higher carbon carboxylics are produced during fermentation, Caprice, Caprylic, Lauric, etc.

    Missing from the chart is another acid, it's not a carboxylic, but common - lactic. Which have a set of very important esters as lactic acid bacteria are very common.

    That's why I did this one. The most common ester combinations - given the most common carboxylics (and lactic) - and the most common alcohols, including methanol and the 4 most common tails alcohols.

    There is a very expensive book called Fenaroli's Handbook of Flavor Ingredients, Sixth Edition @ Amazon that has a table that also classifies most of these into sweet, bittersweet, and bitter, which is pretty fun in the context of cuts.

  • Speaking of expensive books - if someone can gift me a copy of Flavor Creation by John Wright I would be really appreciative.

  • Lol. Hold your breath.

    Don't suppose you would Fenarolis table for us to view....

    Great info there. Thanks for the work on it.

    Are you a chemist or something? What's your background in this area? You always seem to have such insightful comments on chemistry.

    The tables are more extensive than just esters, it's a broad mix of flavor compound types.
