I’ve made a shift to cold-brewed coffee. The benefit of cold brewing that most interested me was the lower acidity. It seems the older I get the more sensitive I’ve become and coffee is particularly problematic source for me mostly because I drink A LOT of it.
You don’t need anything special to cold brew your own coffee. You’ve probably got a jar and some cheesecloth in your kitchen. And, that’s all you need other than some coffee beans. However, I picked up a couple of items to get started with for the sake of convenience.
A burr grinder. It’s a manual grinder that produces ground coffee of uniform size. I already have an electric blade grinder, but the grounds usually end up too fine or too coarse (or a combination of both) because there’s no control other than how long you keep the blade running. And, it does generate a very small amount of heat. Coffee hipsters purists point out that this heating of the beans can release some of the flavor and generate static that causes the grinds to stick everywhere. For me it was really about the consistency of the grounds.
My second purchase was a “Cold Brew Iced Coffee Travel Bottle” that includes a filter for brewing the coffee and makes a handy way to take it to work. Overall, I’m pleased with the bottle. It’s the perfect size for making two large cups of iced coffee; one for the morning and another after lunch when I need the caffeine boost. I’ve been using it for about 2 weeks now and the only issue I’ve had is that the screen of the filter ends pretty much exactly at the plastic “collar” of the top. Because of this, through normal handling the screen bent inward a bit allowing any ground coffee above it to pour freely into the bottle. It’s not a big deal, I pushed the screen back out and handle it a bit more carefully now, and if it was a bit less full of grounds it wouldn’t have spilled anyway. However, if the screen were just a fraction taller it wouldn’t have been an issue at all.
The process is simple. (1) Grind some whole beans, (2) Put the ground coffee into the filter and screw on the cap, (3) Fill the bottle about 3/4 with cold water, (4) Place the filter onto the cap, lower the filter into the bottle and screw on the cap, (5) Put the bottle in the fridge, (6) Wait 8+ hours. Enjoy!
