How to take a picture like this?

I want to put together a menu taking pictures of my own food and drinks
How would you take a picture like the one I linked to?

I would like to learn how to do a pure white or black background.

Google "Photographing drinks" There are thousands of tutorials. Here is one.

Awesome, much appreciated

You will need at freshly brewed pot of tea (allowed to cool), some plastic prop ice cubes (won't melt) and at least two bottles of whiskey.

Put the prop ice cubes in the glass and poor in the tea. Now start watching the videos JJ linked to above and the many many more that you will find once you start googling. There are lots of videos to watch.... which is why you will want two bottle of whiskey to drink while watching them.
