Sine Qua Non was officially founded in 1994 by Manfred and Elaine Krankl and rapidly garnered remarkable critical acclaim for their exceptionally limited production wines made from classical Rhône Valley varieties. From the 2004 vintage, The Rejuvenators is a blend of 56% Roussanne, 24% Viognier and 20% Chardonnay sourced from the Alban and Eleven Confessions Vineyards. There are three distinct front labels.
