In our house, we generally go for variety in our coffee beans. That means when we are finishing one bag, we’re going to open a different bag with totally different beans inside.
What do you do if there aren’t enough old beans to make a full serving of coffee?
It may be heresey, but I mix the final old beans with a few beans from the new bag and call it my “bonus blend”.
I call it my zombie blend. I have a mason jar that I add a little to each time I switch, then when I have enough to do a cold brew I use it for that. I find cold brew to be more forgiving with stale beans.
