Tonight from 6 to 8 PM, Nacional 27 (325 W. Huron) hosts a free launch party for Organic, Shaken, and Stirred, a book on organic cocktails written by food and drink writer Paul Abercrombie (Gourmet, Wine Enthusiast, Washington Post). Sample eco-conscious creations like the Snap-Pea-Irinha — made from gin, snap peas, lime, simple syrup, and black pepper — and watch demos on how to make your own organic drinks at home. Abercrombie will answer questions on how to drink more sustainably, and also sign copies of his book.
