Turns out “Brewing” is not an appropriate term for making mead. ” ‘Brewing’ is an extraction process.” Beers, for instance, extract sugars from malted grains. Herbal teas extract herbal essences from the herbs. There is no such extraction inherent in meadmaking, though meads can include extracts (ie, using herbal teas as a base or braggots using malt sugars).
The proper term is meadmaking.
