Tahoe blue vodka
This is world class vodka, it's a three way blend of grape, corn and sugarcane. Superior to Grey Goose. When you consider the price... a virtual no brainer. Seriously this should become your go to vodka.
A basic test for the quality of any vodka is, can it be consumed without ice, or water, or any other item. Tahoe blue handily passes this test. In fact we prefer to drink Tahoe blue straight.
There is no reason to buy any other kind of vodka.
