It’s all I drink. It’s a good exercise in staying prepared, cause if I run out it takes over 18 hours until my next batch is ready.

Max course grind, 284g of cheap dark roast beans, soak for 18+ hours. A little cream and simple syrup. Delicious. Makes enough concentrate to last about 3 days between my wife and I.


Other than the equipment used I’m doing the same thing! Even the same brand of costco beans.
What equipment do you use? I’ve been making cold brew for nearly 7 years now and have tried a few different methods.
I have basically a big mason jar with a wire filter that is sort of a cone that fits inside. I grind 100g of beans in a blender and pour it into the jar then add water. I then put the filter in and the cap, which has a handle and pouring spout. That is backward from the intended use. The grounds are supposed to be in the filter, but I find that a bunch of the grounds end up floating above the water when I use it that way.
After a few days in the fridge, I pour the coffee out into another container and reset.
The filter is the only part of the setup that is really specialized. If I wanted to use a coffee filter and a sieve I could do it all with no specialized equipment. But the filter jar was a gift, so I do it this way.
