Winery Equipment Testimonial:

"Upgrading your winery from 1000 cases per year to 3000 to 5000 can be a daunting task. The choices in winery equipment, capacity and price vary all over the place. The great thing about Ryan is, having been a wine maker for years, he knows how to design things from start to finish. When I harvested my first ten tons of the year at 6:30 a.m., Ryan and his staff were there making sure everything was working correctly. I knew I had made a good decision."

The Science Behind the Process

The phenolic compounds - natural phenol and polyphenols - in wine include a large group of several hundred chemical compounds that affect the taste, color and mouthfeel of wine. These compounds include phenolic acids, stilbenes, flavonols, dihydroflavonols, anthocyanins, flavanol monomers (catechins) and flavanol polymers (proanthocyanidins). This large group of natural phenols can be broadly separated into two categories - flavonoids and non-flavonoids. Flavonoids include the anthocyanins and tannins which contribute to the color and mouthfeel of the wine. The non-flavonoids include the stilbenoids such as resveratrol and phenolic acids such as benzoic, caffeic and cinnamic acids.
