After two weeks the sarsparilla root extract tastes about how the vanilla extract would taste. The flavor of the sarsparilla is there and strong, but the flavor of the vodka is still quite present. I am going to let this go another four weeks and report on it again. So check back on March 3. However, overall the flavor is earthy and unique. I think this is really going to turn out well and I will likely start a larger batch in the mean time so that it is ready close to this test batch.
