Every Wednesday from 3-6 PM there are free wine tastings at Sherry-Lehmann Wine & Sprits (679 Madison Ave., NYC). Next week features Spanish Rioja from CUNE and the following week (January 29th), "[t]he incredible single vineyard Cabernet Sauvignons of Lokoya," whose bottles are in the $150 range. If you've got the time, you can't beat sipping on some really expensive wine for free.
