U Street Girl (re)tweets that Cork Market, the adjunct space that recently opened up the road from Cork Wine Bar on 14th Street NW, is offering free wine tastings today from 1 p.m. to 6 p.m. On a warm day like today, I favor a Riesling or a sparkling Shiraz, but I wouldn’t pretend that I know wine better than the next guy. If you sample anything today, leave a note with your recommendation, will you?
