Just wanted to let you know I've perfected home made iced coffee, rivals any cafe style trust me!
(but if you're not a nestle fan don't read on)

Found a product called Nescafe Short Black, its completely powdered, not granules. Its designed for making short blacks at home, you're supposed to make it in an expresso cup. But here's what i do:

4 teaspoons NSB in a large glass (I like it strong)
+ 2 Tablespoons boiling water
2 teaspoons of sugar (up to you how much)
Mix (no need to leave to brew)
Then add about 250 milk, stir vigorously.
Should actually be cold since you're hardly using any hot water, but if you want it more icey add an ice cube or 2. I usually add one, stir again and chuck it in the sink. (the ice cube)

Drink. Delicious!
