I just started trying this with Merlot, as it is a mild red wine. I measured out a bottle of 750ml into 5 parts and then reduced a little, so that a normal bottle of wine should last 5 days, if only half a cup (4 ounces) is drunk with dinner, measuring it in a metric cup. This is an old study actually. Garlic also increases longevity, as well as Turmeric, which can be got in curry powder.
