• HONEST WASHINGTON SPARKLING WINE •

Tirriddis is a Washington State traditional method sparkling wine winery located in Prosser, Washington. Founded in 2021 by Andrew Gerow, Gabriel Crowell, and Matthew Doutney, three graduates of Washington State University’s Viticulture & Enology program. We are happily working hard to pioneer & curate Washington’s sparkling identity.

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 diverse yet 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.

Defining Us


processed-57EF9E38-7BCF-4739-9C6F-1FE4C1F5E967

Washington State sparkling winery devoted to premium, original, and authentic traditional method sparkling wines. The name comes from the three step process that it takes to make traditional method sparkling wines – Tirage, Riddle, and Disgorge.

The act of blending wine, yeast, and sugar and putting into bottle to trigger a secondary fermentation in the bottle. The yeast consumes all of the sugar and produces the natural carbonation in the bottle. The first step of the traditional method sparkling process

The in-bottle, natural settling process where the bottles are slowly rotated and tilted upside-down to catch all the yeast in the neck of the bottle. The second step in the traditional method sparkling process.

The process where the neck of a riddled sparkling wine bottle is frozen, turning the settled yeast into a solid puck. The bottle is then opened, causing the frozen yeast to be ejected by the natural pressure in the bottle.

This leaves us with a brilliant, clean sparkling wine with fine, long-lasting bubbles. The third step in the traditional method sparkling process.
