(SMH) - In the bar overlooking the twisting vines in India's answer to the Barossa Valley, a group of friends from Mumbai enjoy a weekend getaway -- and a chance to brush up on their new wine-drinking hobby. "I've been teetotal all my life, but quite recently I started to drink wine. It's a growing trend," said 30-year-old housewife Jol Kapadia, sipping on a glass of Chenin Blanc at Sula Vineyards.
