Cole’s Perfect Nitro Cold Brew
As discussed in episode 29 of the show.
If you love coffee, then you haven’t lived until you’ve made yourself a scientifically perfect cup of nitro cold brew coffee.
Is it a lot of effort? I’ll admit it seems like a lot of work at first, but once you get the process down its worth every second. I would even venture to say it’s easy.
Nitro cold brew is something not many people fully understand or appreciate, but that all changes today when you read Cole the Science Dude’s recipe. He spent months conducting legit experiments to figure out how and why nitro coffee is so magical, and if you listen to episode 29 of the show, you’ll know what that effort was all about.
So follow these steps to the letter and don’t be afraid to reach out to us or Cole if you need help.
It's all in the beans. You need to get yourself some Arabica beans grown in a high altitude location like Ethiopia. Make sure they’re naturally processed, aka fermentation processed. Then ideally, make sure they were medium roasted. When you get to the point of mixing the water and the coffee grounds, the ratio is 236.5 mL of water to 28 grams of coffee grounds. This Scales up and down as needed. That translates to about 4 tablespoons of coffee for each cup of water.
You’re going to need a way to infuse the nitrogen. So you will need a nitro whipper to get this done. You have 2 options...if you have the funding you can buy the unit Cole suggested in the episode here.
If that's a little out of reach for you, Griz used one similar to this.
Get yourself some good filtered water. Under no circumstances should you use treated tap water for this masterpiece because it will ruin the flavor.
Now for the actual chemistry!!
-Grind your beans to a medium coarse consistency.
-Mix your water and coffee grounds in a glass container or pitcher. Make sure you stir it at the beginning and periodically throughout its time in the fridge.
-Loosely cover the container and put it in the fridge for 12-18 hours.
-Remove the coffee mix from the fridge, and pour it through a filter to remove the coffee grounds.
-Pour the freshly filtered coffee into your new nitro whipper, and infuse the nitrogen.
-Pour your sweet sweet nectars into a mug, and enjoy the fruits of your glorious scientific labor.
