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”.
Yeah, I stress about this a little as well. I’m all pumped to experience the new roast but by mixing in the old I know I’m not getting the signature of it for that first brew. I still do it though, I’m not gonna waste good beans and it’s usually just fine. I find that the mix usually isn’t as good as either bean on its own and it gives me some real respect for blend masters that are able to make good bean blends.
