Regardless of the Noilly Prat bottle rotting on your parents’ liquor shelf, wine-based spirits—fortified wines, aperitifs, digestifs and vermouth, especially—should be refrigerated after opening. Khoury’s Fine Wine & Spirits owner Issa Khoury recently held an in-store seminar about just this issue, and says that vermouths such as Dolin should all be treated like wine: refrigerated after opening and consumed within a week if possible, but certainly within a month. Whether you mix them into cocktails or enjoy them on the rocks (yes, vermouth is divine on its own), it’s never better than from a freshly cracked bottle. Hence, Khoury offers Dolin vermouth in 375-milliliter bottles for just $12. KhourysFineWine.com.
