Are you a coffee paste person? You might be! Several people are—mostly ultralight backpackers. I am not. Or at least I don't think I am based on three cups made with this Swiss startup's unique product. The only flavor is bitterness, and it turns a weird grey color with a splash of milk. But then again, I have so far only tested it in my kitchen against a delicious AeroPress cup and not in the wild after carrying its 5 ounces for 15 miles up and down hills. I do not want to reveal too many of our top-secret editorial plans to competitors, but Scott Gilbertson and I have been talking about ways to assess saving weight when backpacking, which is why I bought and tested this. With the tube weighing just 4.76 ounces when full with 20 servings, it's going to save you at least half a pound. The tube is sturdy, it's dead simple to use, and my opinion might change sitting around a campfire. Mostly, though, I am mad that I paid $20 for my tube when Prime Day has it priced at $13. For all the “Prime Day deals aren't real” people on Blue Sky Dot Com: I had this product sitting in my cart for two months, and it never dropped below $20 until now. For $13, this is definitely worth trying on a backpacking trip.
