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”.
Same, we got good quality beans and expresso machine anyway, so having a blend is a surprising but wonderful cup of coffee.
