March Madness would be so much more fun if there were wine involved. Happily, the oenophiles from North Andover’s Wine ConneXtion have tweaked the month-long tournament to bring us March Wine Madness. Every Saturday this month, beginning on the 10th, the store will feature ten wines, all of which retail for under $25, handpicked by those who know best from places like Davio’s, Post 390, Bokx 109 American Prime, Poe’s Kitchen, Scampo, Bondir, Beacon Hill Bistro, Brasserie 28, The Beehive, Coppa, Taranta, Tryst and Petit Robert Central in a taste-off voted on by you. After the day’s tasting, each of the three top vote-getting wines from each week will move on to the final round of tasting on Saturday, March 31st when only one wine will be crowned the winner. Each tasting runs from 12:00 to 5:00pm and is free to the (over 21) public.
