There are quite a few lady winemakers in the US. We do not seem to have
many widely read lady wine critics. However the UK has many lady
authors of wine books, wine auction house employees, and several lady
MWs. France has quite a few ladies very interested in wine. Mme. Leroy
comes to mind. Her life seems to be dedicated to making the best wine
possible. Although she is not a large woman, you had best be well
prepared if you discuss wines with her, because she has a reputation of
not suffering fools lightly.

In the 1800s, low-acidity, light sweet wines, very sweet sherry, and
spirits such as creme de rose, etc often were called ladies drinks. I
have no idea if such language was based on fact. I doubt if anyone made
controlled surveys then to see if ladies really liked low acid and
sweeter wines more than men. I doubt it. The men could drink plenty of
sweet port then. They might select Drambuie over creme de rose, but one
can hardly say that this was because Drambuie is not sweet.
