Because of the duty, wine may be the most expensive food product we consume, so Im thinking of producing my own. As grapes are vines I think it may be possible to grow one up each fruit tree, especially given that grapes root deep while citrus are surface feeders so they wont compete for moisture and nutrients. The only problem is will the Auckland climate (summer day length) ripen red varieties? Ive read that Akl is suitable for Riesling but not Pinot Noir. I want to grow red for the health benefits cited in the French paradox. If red wine really does reduce the risk of cardio-vascular disease shouldnt the government remove the duty on it?
