298: Unrivaled Russian River Pinot Noir and Sonoma Wines with Theresa Heredia of Gary Farrell Winery

Does harvesting wine based on the biodynamic calendar make sense? What about actually drinking the wine based on the lunar cycle? How does fog play a profound role in growing grapes and winemaking in the Russian River Valley of Sonoma, California? Why do some winemakers add Mega Purple to wine, and what the heck is Mega Purple?

How did Theresa approach making the wines her own over the years at Gary Farrell Winery? What makes the Russian River Valley AVA unique in Sonoma? How does fog influence the development of grapes in a vineyard?   Key Takeaways The lunar cycle is correlated to gravitational forces. So if you pick on a root day, the theory is that you're not going to capture as much of the aromatics as you would on a fruit day when the gravitational forces are the weakest. The fog and diurnal temperature shifts help preserve acidity and color development in the grapes. It can get up to 90 degrees Fahrenheit in the daytime, but at night, the grapes cool down to fog temperature, which is about 50-55 degrees. So you get that big swing in temperatures called a diurnal shift. Mega Purple is highly concentrated grape juice made from Rubired grapes. Winemakers use Mega Purple to add color, body and texture, and make bigger, bolder wines.   About Theresa Heredia Theresa Heredia started her career at Saintsbury and has also worked at Joseph Phelps Vineyards and Domaine de Montille in France.
