The choice of vodka would vary depending on how you propose drinking it. Always choose a rye or wheat-based vodka, which has had at least 3 distillations and 10 filtrations.
The alcohol level should ideally be below 43°.If you plan having it with caviar or smoked salmon, you should choose a non-flavoured vodka (even bison-grass is not recommended).
Always serve it well-iced.You can be less demanding when drinking cocktails (vodkas with higher alcohol levels) or long drinks (flavoured vodkas).
