Why does beer carry a fruity, floral edge?
Beer is fermented grain — starchy, bitter, yeasty. Yet the finished glass often registers as something closer to a fruit bowl or a flower market. Yeast metabolism is largely responsible.
Three compounds — one from ester synthesis, one from amino acid catabolism, one from the hop cone itself — converge in the finished glass to push beer's aroma well outside the grain-and-water story its ingredients suggest.

OAV (Odor Activity Value) = concentration ÷ detection threshold. Numbers above 1 mean the compound contributes detectably to aroma.
