The popularity of iced coffee drinks is still booming this summer, so don't hesitate to brew some up. They are particularly nice when you have friends over. I think they are a bit more sophisticated than regular soft drinks. And all that caffeine will help a party along.
Coffee Ice Cubes
Don't let your coffee drinks get watered down with plain ice cubes. Freeze some coffee ahead of time in an ice cube tray. For a fancy touch, add a couple of whole roasted coffee beans to each cube. Warn your guests though. When the cubes melt, you don't want folks choking on the loose beans.

Rock Sugar Swizzle Sticks
These are a sweet and fun addition to any drink, if you ask me. They are just simple stir sticks, covered in thick rock candy at the end.

You should brew your coffee ahead of time, to give it time to cool before preparing your iced coffees. Though some recipes call for hot coffee to start with, most drinks will be far frostier if you chill the coffee thoroughly first. Don't leave it out for too long while still warm. Pop your coffee into the refrigerator once it's down to room temperature, both to cool it and to keep bacteria at bay.
Jazz up the Whipped Cream
A lot of good iced coffee recipes call for whipped cream on top for the finishing touch. Don't settle for a dull dollop! It's not hard to make delicious flavoured whipped cream to jazz up your drinks.

Get a Cocktail Shaker
This is a particularly nice touch if you are serving up your coffee drinks while entertaining friends. Giving your drinks a good shake-up will make them extra frothy. Not recommended for sparkling drinks with club soda.
Use a Cold Brew Method
I can't actually vouch for this but it's something to think about. If you shy away from making iced coffee because your house is hot and you don't want to fire up the coffee maker, you could try using a cold water method of coffee brewing. You typically have to soak the coffee grounds overnight in cold water, rather than heating the water.
