It’s okay to drink alone for educational purposes. The International Wine Center in midtown now features an online wine certification through the Wine & Spirit Education Trust based in London. The five-week course covers regions, production, and labeling; the first session begins January 15 and concludes with an exam at the IWC on February 25. In addition to paying $428 for the course, you must bring your own wine for the chat-room tastings. If abbreviated free lessons will do, legendary Brit Master of Wine Jancis Robinson discusses wine regions in three-minute videos on the WSET website. So, slap a shot of misty vineyards on your desktop. On the Internet, nobody knows you’re a drunk.
