Soon, picturesque Autumn will become frigid Winter, and you'll be relegated to your couch to watch Wings. So while it's still nice and Steven Weber-free out, hit the streets of the South End and Back Bay to get your vino fix on this free wine tasting tour.4pm:Bauer Wines (2-5pm)330 Newbury St, btw Massachusetts and Hereford; 617.262.0363: Chipotle's providing "snacks" like guac, chips, and salsa that Bauer'll pair with sauvignon blancs and other varietals that go perfectly with "where the hell is my burrito?". 4:30pm:Best Cellars (4-7pm)745 Boylston St, btw Exeter and Fairfield; 617.266.2900: Showcased wines will include selections from the Loire Valley and some "French sparklings" -- wines that badly want to be called champagne, but due to traditional French classism, always seem to get merde'd on. 5pm:Charles St. Liquors (5-8pm)143 Charles St, btw Cambridge and Revere; 617.523.5051: While they haven't yet decided what they'll be pouring, CSL has a stellar rep for stocking choice wines, so hopefully they'll pull out all the stops (Thunderbird AND Boone's Farm?). 5:30pm:South End Formaggio (3-6pm)268 Shawmut Ave, btw Hanson and Milford; 617.350.6996: A selection of three biodynamic wines from producers like Chateau de Roquefort and Chateau Tour Grise -- French winemakers with an astounding six-mile long wine cellar, good for brochure, wearying for cellar workers. 6pm:Brix Wine Shop (6-8pm)1284 Washington St, at Savoy; 617.542.2749: A rep from Rosenthal Wine Merchant will be pouring a selection of pre-Thanksgiving picks, which could probably also be called "wines you better drink now" or "sell by Oct 30".
