Ok so I tested these out last night. Grey Goose and Pravda. Going into the tests, I thought maybe Pravda would be the cleaner smoother or the two. Having not tried it before, I was quite surprised. I actually enjoyed the grey goose more. The Pravda was leaving me with some sort of aftertaste...almost grainy in a way...not sure exactly how to explain it. It was hard to tell which was "cleaner" than the other.
So then I mixed each up to my drink of choice...the gimlet. I first tried the Pravda, and it was fine, but again some sort of aftertaste I wasn't expecting. Then I did the same with the GG, and I felt the GG was a better mixer.
Really I think a better test would be Pravda or GG versus Absolut or Smirnoff. I normally drink 3 olives, and on occasion Tito's Handmade.
In between I had a Rocky Patel Edge Sumatra, which I found to compliment both drinks very well. I may just be biased to the GG, so I will have to purchase a bottle of Pravda to try and prove it out one way or the other. All in all, was fun to do, and thanks very much for the opportunity!
