My Wife and I spent 3 nights getting unintentionally trashed, trying to come up with the perfect blend of flavors and suitable effect. Beware, this drink is deceptively strong.

*note - i've reduced all measurements to cup values. For large mixes, you can step up to the equivalent in gallons.

1/2 Cup - Apple Juice

1/2 Cup - Cranberry Juice

2/3 Cup - Pomegranite Juice

1/4 Cup - Blueberry Juice

1/3 Cup - Passionfruit Juice

2/3 Cup - Zombie Guts (Sorry folks - secret flavor :P the drink will work fine without this)

7 oz  - Svedka Vodka

3 oz  - Sapphire Gin

1.5 oz - Cointreau

Mix and let steep over night, chilled.***       Serve cold, or over ice.

*** This is very important. To allow the flavors from the juices and alcohols to blend, while still giving their individual "attitude" to the drink - you have to allow the alcohols to start digesting some of the sugars in the juices.  This avoids the syrupy texture you get from a freshly mixed multi-juice concoction.

For this mix, a smooth vodka was chosen intentionally.  Svedka is barely noticeable in a juice mix. Tito's and Goose are also good choices. Sapphire was added to give the drink some bite. The cointreau is the bridge flavor between the bitterness of the alcohol and sweetness of the juices. If you choose a sharper vodka  (Absolut, Skyy, or Stoli for instance) then the gin can be eliminated,  as the two tastes won't mix well
