Justin Vineyard’s famous Isosceles, the Paso Robles winery’s Bordeaux-style flagship wine celebrating its 25th year, has been described as offering aromas of “plump, dark blueberry, tart Bing cherry and bay leaf” and a palate of “crushed herbs.” But is the blend of Cabernet Sauvignon, Merlot, and Cabernet Franc a true isosceles of varietals (a la the triangle you measured in grade-school geometry)? Only master class students of Justin’s master sommelier Joseph Spellman and Wynn Executive Director of Wine Mark Thomas will be able to answer that question, after an intensive – and delicious – blending class in the Vista Room at Lakeside, designed to replicate the flavor of the famous wine. Spellman’s appearance at Wynn is a repeat of a first, successful class during the holidays, Thomas explains. “Joe’s approach is to give the background and the history of Justin Vineyards – because there is so much history there,” he says. “He talks about the genesis of the Justin Isosceles, going through the vintage, the year, the growing conditions, and then we’ll get to the flavor profiles of each varietal.” And although the classroom will be set up with scientific-looking graduated cylinders for blending, “The point is to have fun tasting and see the progression of how the addition of a bit more of each varietal changes the aromatics.” Still, expect at least some of the attendees in the class capped at 40 to get a bit competitive about cracking the Justin Isosceles code. Spellman has reported that several students in the last class got “pretty close,” Thomas says. Regardless of your blending success, graduates leave with a vintner certificate and a keepsake bottle from Justin. Success, indeed.
