It might seem strange to hang the word “straight” on a Vodka. But they do this to differentiate this spirit from the several gentle Vodka infusion products that they offer. DSP Vodka Straight may indeed be “straight,” but it is also very complex. The spirit base is a combination of lightly sweet white wines — Riesling and Viognier — and wheat. It is double-distilled, first in an antique Cognac still and then in a Holstein pot still. The combination develops a perfect texture that lingers richly on the palate.
