Are there any vodka cocktail recipes for someone who likes whisky/scotch? I typically drink brown spirits, however, I have some vodka left over from a wedding party so I was wondering if there are any good vodka cocktail recipes which aren't too sweet (or have too many ingredients) and would be enjoyed by someone who has a pallet for whisky/scotch.
Here are few cocktails that I can recommend and don't require much ingredients:

1) Black Russian - Vodka and coffee liqueur 

2) Screwdriver - Vodka and orange juice 

3) Greyhound - Vodka and grape juice 

4) Vodka Martini - My favorite
