Vietti Winery 2011
Most of us are well familiar with the term maceration, the process by which the “phenolic” components of the grapes, the tannins, anthocyanins (color), and flavinoids are leached from the grape skins, seeds and stems into the must. Essentially, maceration is the process that lends red color to red wine. In white wines, maceration is either avoided or permitted in a very limited manner.

Chances are, the last time you enjoyed a glass of red wine, that you gave much thought to why the wine looked, smelled and tasted as it did. Unless you’re steeped in the biochemistry field, you (and I) are simply searching for that well balanced red that can be enjoyed on its own or with food. But have you ever given thought to why a red looks, smells, tastes and “feels” the way it does in your mouth? What is it that makes it the perfect match for food or alternatively, what is it that simply fights with a dish? The answer lies within the field of biochemistry.
If not already, familiarize yourself with the term phenol. While I have no intention of launching into a detailed discussion about the chemical structure of this group of several hundred compounds, they all have a common structural element, a hydroxyl group (-OH) bonded directly to an aromatic hydrocarbon group. But oh yes, I promised that I would steer clear of biochemistry. Anyway, bond more than one phenol together and you get……….polyphenols.

While the heavyweights of Bordeaux, Burgundy, Rhone and Piedmont often grab the headlines, another relative has hidden in obscurity…. until recently. I’m referring to the Rose. Now finally, this delicious and easy drinking summertime wine is receiving the recognition that it so richly deserves due to an improvement in quality, food friendliness and affordability; its popularity is reflected in a 50% domestic export increase in 2006 over the year prior. Restaurants and wine retailers, which used to barely acknowledge rose wine, now dedicate space on their menus and shelves respectively. What’s more, the early presence and late departure of Arizona summer heat lends itself to this refreshing treat.
Rose is a natural during the summer season whether it be with food or stand alone. Its refreshing aromas of cherry, strawberry and watermelon, relatively low alcohol content (12.5-14%) and just the slightest hint of tannin in some wines, balance the easy drinking wine with perfection.
