Here’s a fun fact for you: caffeine is water soluble. That means, all things being equal, the longer water is touching coffee grounds, the more caffeine in the cup.
Today we’re talking about brewing cold brew, which has the most caffeine compared to other brewing methods. You might remember it’s also one of the most sustainable ways of making coffee.
Ingredients/Supplies:
- Quart sized jar with lid (We LOVE the Rumble Jar. Not an affiliate link, we just think it’s nifty!)
- Coarsely ground coffee
- Cold water (also hot water for our super secret pro tip)
- Stainless steel mesh strainer and/or canvas bag to hold grounds
Steps:
First, add approximately 70 grams (almost 2.5oz) of coffee to your strainer. Then add your strainer to your jar.
(This is the amount we like for a quart jar. Make adjustments based on how weak or strong you like your cold brew. Remember, we typically cut cold brew with water before serving. More on that below.)
Next, fill the rest of the jar with water.
Let the coffee sit on the counter for at least 8 hours or in the fridge for 24.
After that, remove your strainer. For an extra clean cup, pour the coffee through a canvas bag or paper filter.
This recipe makes a cold brew concentrate, which means it’s very strong. Typically, concentrate is ‘cut’ with water, meaning for whatever volume cold brew concentrate, add an equal amount of water to it. This, of course, depends on how you like the taste, so try it as concentrate and add water (or ice) until you like the outcome.
Finally, store your cold brew in the fridge and enjoy! Try to use it within a week for best taste.
Here’s a few things to keep in mind when making cold brew:
- Remember how brewing time affects the taste of coffee. If it’s sour, let it brew for longer. If it gets bitter, brew shorter next time.
- Super secret pro tip: First, bloom the coffee with hot water for a brighter end result. (Remember, blooming the coffee means to pour on just enough hot water to get all the grounds wet, and then let them extract for about 30 seconds. The grounds expand when wet, so pouring on just a little hot water keeps them from being compacted, and you get a better flavor.) Then fill up with cold water.
