Changing coffee beans: What do you do when there aren't enough beans to make a final brew?
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".
Unless it's a single origin bean, it's probably a blend anyway. I just blend the leftovers with the new beans and call it a good cup. I'll try to find a complimentary roast, though. e.g. mixing a light roast with a dark roast leads to an odd cup.
Honestly? I just fill the remaining weight in the grinder with whatever I've opened to brew next. Unless the old beans are getting stale, then I just bin the tiny remaining amount.
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.
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.
I usually mix grounds and deal with a weird cup but you can also mix a small number of grounds with vanilla ice cream as a topping. I'm sure it can be an additive to a few other things, as long as it's fine enough but to disrupt the texture of things too much.
Sometimes if I'm feeling classy I'll grind the rest and set them aside to make cold brew with later. That's more forgiving so I do it to use up old, stale beans that I end up with for whatever reasons.
Most of the time I don't care and I just top off the weight with whatever I'm using next and drink whatever comes out. It's usually fine, and when it's not it's at least novel.
Coffee grounds can be added to enhance almost any chocolate dessert, in my experience. I use such times as an excuse to make brownies (go go Costco's Godiva brownie mix!) for the kids and I.
I pour my old grounds out of my storage bag into a small bowl, pour my new grounds into my storage bag, then I pour the old grounds on top of my new grounds, and they should get used first.
I don't shake my storage bag to mix the old grounds and the new evenly.
I usually have a few bags on the go as well, variety is nice. Once there's not enough left for a cup I'll wait until another bag is in a similar state and combine. Sure it's not as fresh and sometimes it'll be a weird blend, but usually super good enough.
