It claims that drinking Armagnac is good for your heart, provided that it is only imbibed in moderation, a caveat among the small print that may escape dedicated Armagnac drinkers. After something of a slump, Armagnac sales are on the rise, helped by exports to Spain, the principal European market, followed by Germany and the UK.
