Stage alcohol

Stage Alcohol.  I recently did the props for a production which called for the actors to drink an awful lot of red wine.  Hurray for black currant juice!  Very palatable, once we'd established mix of juice to water.  I found that adding a couple of drops of blue food colouring to the bottle gave a good colour on stage. 

I never got the chance to fiddle with the "whiskey" though.  Had to use flat dry giner ale due to quantity to be drunk and apple juice, whilst it's a better colour, can have a nasty effect on digesitve systems if drunk to excess.  A single drop of yellow maybe?

Anyone got any tips for a good "white wine"?  Will probably come up in next farce and I'm anxious to avoid the lime juice the director has suggested as it tastes vile (well, it does to me and a couple of other actors I know so...)
