I created my own Cold Brew maker. I bought a half gallon/2 quart/64oz. Rubbermaid pitcher, it is translucent white with a red lid that seals completely when the opening is turned away from the pour spout. I paid around $3 for it at Walmart. Then I special ordered “3 gallon sized” Bunn coffee filters from Walmart’s website. They are for commercial coffee makers. If I recall correctly, it was a box of 1500 + for less than $20. I fill one large filter full of about 20-24 tablespoons of ground coffee & tie it shut with a long twist tie. (I prefer very dark, bold coffees). Put that in the pitcher, top with cold water (filtered, if possible) to the top, & cover tightly with the lid. Put it in the fridge for 18-24 hours, occasionally give the pitcher a jiggle if I want. Then, once brewed, remove the filter, give it a very gentle squeeze, carefully remove the twist tie, to save for later, & throw away or compost the filter full of grounds. Extremely simple & easy to do!!! And I use a 1/4 cup scoop instead of a regular coffee grounds scoop or tablespoon to make measuring out the grounds quicker. It only takes a few minutes to set up or dispose. This system works excellent! And it’s very inexpensive, with really no mess or clean up, other than washing out the pitcher occasionally. I had previously tried many store bought brewers, coffee presses, & even mason jars that then needed filtered, or special filter bags. This is by far my favorite method! Plus, the Rubbermaid pitcher can always be used for other drinks down the road. And this pitcher fits perfectly on my fridge shelf or door, even better than all the others. I can even do two side by side on my top shelf; one regular & one decaf, for those days when I want some cold brew in the evenings or mornings. Each 64oz brew last me about a week of concentrate. ;)
