The Summer of Riesling is a yearly campaign put together by acidhounds — as fans of the versatile white grape are known — to showcase the diversity of this French wine. Bars all over the US are offering at least three Rieslings by the glass each day, in addition to specials and tastings in honor of the promotion. If you think Riesling is just an overly-sweet dessert wine, check out what’s going on in Philadelphia this summer and take the opportunity to change your mind.
