WebEsters are created when alcohol and acid molecules interact and integrate with each other, which occurs during the fermentation, distillation and maturation processes. During fermentation yeast metabolises (digests) sugars in the wort (the sugary liquid produced by mashing). A small amount of these sugars are broken down by the yeast into acids ... Webesters.
