Tirriddis is a Washington State traditional method sparkling wine winery located in Prosser, Washington. Founded in 2020 by Andrew Gerow, Gabriel Crowell, and Matthew Doutney, three graduates of Washington State Universities Viticulture & Enology program. Our name, Tirriddis, comes from Tirage, Riddle, and Disgorge the three steps to naturally produce sparkling wines. Focused solely on this traditional method, we proudly implement ground-breaking and unique “non-traditional” styles to emphasize Washington’s world class growing environment. In addition to wine quality, sustainability within the community and our environment is very important to us as we strive to help represent and push forward the future of Washington wine.
