All this information is enough to raise one's blood pressure, so I made an appointment with some the doctors involved in our wine industry for a diagnosis.
"I've seen little strong evidence linking moderate wine consumption and poor health," says Forrest Estate's Dr John Forrest. "By moderate I'm talking 1-2 glasses daily, depending on sex, size and age, while the early trimester of pregnancy does appear to be a time when alcohol is better restricted as relatively low levels of alcohol may slow fetal development."
Forrest considers wine's social aspect could also be health-giving. "How often do you use wine as a means to relax, improve your mental state, rest or improve interaction with other people?" he asks. "It's my opinion that it's these beneficial social effects of moderate wine consumption that are at the heart of the French Paradox!"
Ostler Vineyard's Dr Jim Jerram is a medic who has experienced both the good and ills of alcohol when director of Student Health Services at Otago University and through his research with the Injury Prevention Unit, witnessing first hand the worrying changes in students' drinking.
"I saw the devastating results of the effect of these drinking patterns in male and particularly female students," he notes. "The modern binge drinking trends in young people seem to be epidemic across the globe with alcohol the number one abused drug by far in NZ and most of the world."
However, in his personal journey through wine Jerram said he learned that "wine was more than just an alcoholic drink" and something offering sensory enjoyment and reflection. When he set up his own vineyard, he opted to concentrate on high quality wine given his experiences in the health service.
"By setting the standards in our operation at the highest quality I felt I could justify alcohol production in that form," he explains. "Expensive, high-end wines are unlikely to be abused in the way that RTDs, spirits generally and beer are abused."
"As usual it comes back to the old adage of "all things in moderation" and a balanced diet and life style," concludes Jerram. "An Australian lifestyle guru I once heard speak said 'all things in moderation except vegetables, laughter, rice, fish and sex - and if you don't want the sex have more rice!"'
SALUBRIOUS CHOICES
As the positive polyphenols are present in a grape's skin, wines which contain the most are largely reds as they're fermented with their skins unlike most whites. Varieties such as tannat, malbec and cabernet sauvignon have some of the thickest skins, boosting levels further.

MAGNIFICENT MALBEC
