Why do some liquids need to be aerated?

Aeration, also known as breathing, allows volatile alcohols and harsh chemical notes from certain concentrated aromas to escape. This step is particularly useful for fruity or alcohol-based flavors that may have a sharp edge or a varnish-like smell right after the initial mixing.

By leaving the cap off for a few hours, you encourage the evaporation of light solvents, which softens the overall profile and makes room for subtle aromatic nuances. However, be careful not to exceed one night of exposure, as you risk heavily oxidizing the nicotine or losing the recipe's potency through excessive evaporation. In short, a little fresh air helps your liquid relax without letting its flavor vanish. Finding the right balance between closed steeping and flash aeration is the secret to the smoothest blends.
