More harvest know-how continues in my blog this month along with other cellar and vineyard post-season matters. Today I am comparing the difference between Cabernet Sauvignon which has just completed its’ fermentation process and gone through the press with a current release that is three years older. The new wine has just spent 10 days in a temperature controlled stainless steel tank with the cap of skins where all the color and flavor is stored. Pumpovers each day ensure the juice is in frequent contact with the cap. The differences aren’t too far apart when you look at the depth of color in the glasses-it is quite opaque. I see the real difference in the rim of the wine.
The brilliant purple color of the new wine contrasts with the browner, reddish tones of the Cabernet that has been aged for one year in oak and bottle aged for another. In a few months the new Cabernet will be put to bed for its’ year in oak around January. The process of aging the wine will soften it, the color will also change from the deep purple to a red or garnet hue through the slow oxidation over the twelve months. When the wine is bottled and continues aging it also begins to change color but this is a slow process, taking several years, and ultimately fades a bit with time.
Thanks to Robert F. for sending the photo of our 1974 Cabernet-you can see the color change in this now 40 year old wine. A splash of Cabernet, young or old, in my Dino today!
