HOT coffee brewed COLD.

Unbeknownst to many, you can actually make hot coffee using cold brew concentrate.

The idea is simply to top off a couple of ounces of concentrate with boiling hot water. This heats up the concentrate and gives you a warm, but not scalding, mug.

To maximize heat, brew your cold brew a strong concentration so that, when it’s time to mix with hot water, you can use as much hot water as possible. For example, two ounces of cold concentrate and six ounces of hot water will end up hotter than four ounces of concentrate and four ounces of water.

Hot cold brew coffee is actually extremely convenient if you’re low on time in the mornings. Just make a big batch of cold brew over the weekend, then each morning you simply warm up water in a kettle and mix your brew. It’s quicker than making coffee fresh each morning but still delicious.

As far as flavors go, hot-cold brew coffee is a little different—not everyone will love it.

Cold brewing produces up to 66% less acidity and bitterness, so you shouldn’t expect the hot mug to have that usual punch that fresh coffee has. It’ll be smooth and sweet, but it won’t have that usual tang or those lower deep flavor notes.
