A few things to unpack here:

First – entertain getting a Bluetooth or wifi enabled thermal receipt printer. There are options well under $100. I put one in the kitchen on a whim and use it all the time. I can print photos at low but acceptable resolution and notes from any document editor on my phone. They are ultra-fast and many can automatically snip the note for you – no messy tearing necessary. They especially excel over a pen and stack of post-its when you want to create multiple copies. Also, I have horrendous handwriting (like can’t read my own notes bad sometimes), so printing a quick “don’t forget lunch in fridge” note is fast and easy. I’d love to figure out a way to get a voice assistant to automatically print notes for me but haven’t found a reasonable solution yet.

As for the actual coffee stuff, the best info I’ve ever seen on freezing coffee is already available here so I’m not going to rehash all that – but definitely worth reading if you’ve never seen this before. I don’t decaf often, but sometimes I’ll do a 50/50 blend of decaf and regular in the late afternoon or just really want to brew a late night cup. The only decaf I’ve been able to tolerate is Ethyl Acetate or Methylene Chloride processed, but these are tricky to come across. I prefer to buy locally, but all my local roasters use Swiss water process. Since I’m not brewing it often, my decaf will start to expire, and I quickly lose interest in mixing stale decaf with a fresh roast of the week. Freezing is easy. While it’s also acceptable to just throw the bag in a ziplock and put it in the freezer, the vials save time on the brewing end. You’ll need a funnel to load these. I also love these for throwing in the freezer at work where I only brew occasionally and need it to be very fast.
