Aeropress does this for me, and way better quality. Less waste too

You can do the same with a manual coffee brewer though- just use less coffee and water

Aeropress

I just wait until I am at work, it's much simpler because the coffee at work is free and I just have to press a button and wait for the cup to be full.

Not hard to find single cup brewers for loose grounds (I own one) and they're cheaper because they don't have to work with Keurig for licensing and compatibility.

Just to illustrate for anyone reading this that brewing coffee can be very easy and quick: I use one of these to very easily brew exactly one cup of coffee every morning in about 2-3 minutes - https://kalitausa.com/products/kalita-style-102-ceramic-coffee-dripper-white (mine is in the beautiful brown color, but I linked the white one because it's much cheaper and has many more reviews)

It says 2-4 cups but I think it's really only for 1-2 cups. It takes #2 filters that you can find at any grocery store. If you want to be even more environment-friendly, you can buy reusable cloth #2 filters online.

Procedure:

• Measure one cup of filtered water, transfer it to a pan or kettle, and start to boil it
• Set up the cone and filter on top of the cup and put one heaping tablespoon of coffee grounds in the filter
• Pour the boiling water in the filter (with a small open pan on the stove top, it takes me about 1-2 minutes to boil one cup of water)
• Optionally, flavor the coffee to taste

When I first decided that I wanted to start drinking coffee I way overthought it, spending all kinds of time and energy researching all kinds of different brewing methods, grinders, etc. It's easy to get lost in the wilderness when it comes to coffee. But I ended up choosing the easiest option available and have been happy with it for years. Hot, fresh, easy, just about any variety and strength of coffee, and no added microplastics from sending boiling water through plastics.
