What gives beer its floral, almost perfumed edge?
Beer is fermented grain — earthy, bitter, yeasty. Yet yeast metabolism quietly loads it with terpenoids and aromatic alcohols more at home in a florist's shop than a brewery.
Three structurally unrelated molecules — a terpenoid, an ester, and an aromatic alcohol — converge to produce a floral register that has nothing to do with hops and everything to do with yeast biochemistry. The grain is almost incidental.

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