So, what's the perfect grind for cold brew? It's not as fine as the sand on a beautiful beach, but more like the pebbles you'd find on a scenic hike. You want it to be coarse enough that the coffee can "breathe" and release its flavors slowly, but not so coarse that it's like trying to drink from a bucket of rocks.
Now, you might be wondering, how do I achieve this perfect grind? Do I need to invest in a fancy grinder or can I just use a rolling pin and get all DIY on my coffee beans? The answer is, you can definitely use a burrs grinder or even a rolling pin if you're feeling adventurous, but be careful not to overdo it - you don't want to end up with coffee dust.
Using a blade grinder is also an option, but it's like using a lawnmower to cut your hair - it might get the job done, but it's not exactly the most precise tool. You want to aim for a grind that's consistent, so your coffee tastes the same every time, not like a box of chocolates - you never know what you're gonna get.
