Cluster Thinning and Low Yield at Clos de la Tech

This is the sixth in a series of blog posts in which Winemaker T.J. Rodgers explains some of the most technically challenging and important aspects of Clos de la Tech’s grape production.

Whenever we have a heavy crop that yields over two tons per acre, we remove the excess clusters to improve wine quality. These clusters are removed only on the afternoon-sun side of the trellis to produce wine made mostly from the superior morning-sun clusters. California Cabernet Sauvignon crop yields routinely fall in the range of 4-5 tons per acre in the Napa Valley to 10-13 tons per acre in the Central Valley—two to seven times our yield. The concentration of flavor and bouquet in wines made from low-yielding, morning-sun bathed clusters is unmistakable.
