I just love Appletini's me and the girls drink them when we go out. It contains vodka and an apple liquer or juice.
I had one before but maybe the bartender didn't make it right was a little tart or is that the taste for it.
That is quite possible. You have to shake or stir the ingredients and then strain into the glass.
That may have been the problem but I'm more of a daiquiri girl mixed with some Ciroc lol or a good Margarita. 
I do like those too, made with rum and lime juice, with a little sugar.
When we have parties for the holidays I usually make the margaritas and I'll make some cosmos as well my friends love those.
That's always a good time.My appletini's are good, although you can vary them and put rum instead of vodka to make a Rumpletini.
I will have to make them on my own so I can get the real taste do you add fruit on the side of the appletinis?
