Coffee is a staple in most households. Thankfully, it can also be made sustainable (however, this post will not address farming practices, I do recommend trying to buy coffee that is fair trade or directly from sustainable farms that are native-owned if it is in your budget).
I used to drink coffee that would be made through a typical, cheap coffee machine. But I found that the water would often get too hot and cause the coffee to burn or become highly acidic. I switched to a cheap plastic pour over and it has become my staple. I haven’t owned a regular coffee maker for years. I added on the coffee sock, a reusable coffee filter and it has been a great feature. It does require some maintenance as you must sanitize it in boiling water for 10 minutes once a week. I also noticed that it is hard to remove the coffee grounds to dispose of them. More grounds go down the drain than I would like.
I didn’t want to have to worry about rinsing out the filter while camping, so I bought a camping pour over. Honestly, I think I like it better than the one I was using before. It comes apart easily for cleaning and the coffee grounds get disposed of more easily so far less goes down the drain.
Of course there are other options such as a french press. But for some reason the taste of french press coffee doesn’t appeal to me.
Now, of course you could throw your used coffee grounds in the trash, but why not try composting them? If you live in such a way that composting is not possible, some plants love coffee grounds added to the soil such as Jade, Azaleas, Christmas Cactus, Ghost Man, and Snake Plant (some plants don’t, so always check before adding coffee grounds to the soil!).
