I've just discovered black vodka, called Blavod.
It's just plain vodka which gets its' color from the bark of some tree.
There are 'lots of Halloween drinks you can make with it.
The Dirty Pumpkin
Pour tumbler glass 3/4 full with orange juice then add Blavod vodka to top. Pour really slowly over a spoon to keep the two separated. If you want ice, add that first.
Substitute the orange juice for cranberry juice and call it a Black Widow
• 3/4 ounce of Blavod (black) vodka
• 1 1/2 ounces of Kahlua
• 2 ounces of cream
Pour Blavod and Kahlua over ice, top with cream and a splash of grenadine.
there are more Blavod halloween drinks on the net, and mixing it with just grape juice is good too.
