How to make iced coffee?

Iced coffee is brewed by the regular method. The brewed coffee is then poured into an ice cube tray and allowed to freeze. When in the mood for iced coffee, take out these cubes and pour milk over them.

This method will result in a thinner coffee with a mild taste. To solve this problem, make a very strong brew so when it is diluted, the flavor is not lost.

How to make cold brew coffee?

Cold-brew takes time. In this method of brewing, the coffee grounds are immersed in cold water and allowed to sit as is for at least 12 hours. 

After 12 hours, the coffee is stepped completely. The coffee grounds are filtered and the coffee concentrate is mixed with water or milk. 

Ice is added to chill it. Cold-brew results in a bitter and acidic flavor since the brew relies on cold water to extract all the oils and flavors from the beans over an extended period of time.


Tips to make the best iced-coffee

Use instant coffee

Instant coffee is often looked down upon for a french press but it works best if you want to make iced coffee. Just mix and stir a heaping tbsp of instant coffee with some warm water and add chilled milk to it. Ice cubes can also be added.

Freeze coffee

Make a paste of coffee and water and dilute it a bit. Pout the mixture to the ice cube tray and freeze. Whenever you want to make iced coffee or iced latte, put some cubes in a mug and pour milk over it, voila, your chilled latte is ready.

Improvise your ice cubes

If you like your iced coffee to be more creamy with a rich flavor and thicker consistency, freeze coffee with milk in the ice cube tray. Use regular milk or coconut milk if you are allergic to dairy. You can add honey for sweetness and flavor.

Serve with Seltzer

Espresso pairs well with sparkling water. You can make your own espresso spritzer at home by pouring espresso shots over ice cubes in a mug followed by some sparkling water to jazz it up.

Refrigerate your beans

Experiments have shown that refrigerated whole coffee beans yield a more even grind, which is the base for a perfect brew. This method is not only suitable for iced coffee but works best for hot coffee as well.
