Pacific Rim Winemakers is a Washington winery owned by Randall Grahm (also owner of Bonny Doon Vineyard in California)[1][1]. Pacific Rim's winery is located in West Richland (Tri Cities area in Eastern Washington) and specializes in Riesling. The wines have been produced since 1992 by Randall Grahm himself and more recently (since the 2006 vintage) by Nicolas Quillé [2]. Pacific Rim produces principally Riesling from Dry to dessert style (seven Riesling in total including several single vineyard sites in the Columbia Valley) and also small amounts of Gewurztraminer and Chenin Blanc.
Pacific Rim is positioning itself as a Riesling expert by the sheer volume of Riesling it makes and the diversity it provides. Pacific Rim's team has also written an extensive book about Riesling published under the name "Riesling Rules" and available on their website [2]
