While we have mentioned two great drink mixing mobile websites before we have never covered any of the on device applications. When a friend of mine asked me if there was one I did a bit of research. I actually heard about Mobile Bartender when I was reading a review by Ryan Blundell on CrackBerry. Looks like a great application according to the review with only a few downsides. You can even enter in the ingredients you have and it will tell you what you can make.
Sadly there is no trial but if you are interested you can pick up the application in the store for $7.95 at the links below:
