The marketing story: Cense Marlborough sauvignon blanc is the first Weight Watchers-branded wine, made by Truett-Hurst, a holding company for California-based wine production and branding operations. Cense has 85 calories per 5 oz glass,* equating to 3 Weight Watchers’ “points.” The partners expect to add other wines to the brand line-up including (surprise, surprise) a rosé.
The numbers: Cense is a reduced alcohol wine. The brand also hooks its diet-friendly message on claims about no added sugar, but dry table wines essentially never contain added sugar, and the small fraction of residual sugar in the vast majority of table wines makes an insignificant calorie contribution. “Lower calorie” is just alternate marketing for “lower alcohol.”
Since ethanol and sugar are the only signficant sources of calories in wine, estimating the calories in your glass of non diet-branded wine is simple.** (Color only matters in that whites are often, though not always lower in alcohol than reds.)
Calories in a 5 oz glass = (alcohol on the label as a decimal)(785) + (sugar in grams/liter) X (.568)
A 12% dry wine with .5% residual sugar clocks in at just about 100 calories per 5 oz. Make that 13.5% – the starting point for sauv blancs from Kim Crawford up to Cloudy Bay and Greywacke – and the same 5 oz glass comes up to 110 calories. By drinking Cense, you save about 35 calories per glass, the equivalent of about 5 almonds or one and a half medium-sized carrots.
The analysis: Does Cense make sense?
