I like the idea, but I am not sure of the purpose. We do many high-mileage, multi-day backpacking trips (16-22 miles/day for 2 to 8 days) and I have yet to find a really good, lightweight way of getting a cup of coffee on the trail. We have tried almost everything (Aeropress, press pot, tea infuser, instant, etc.) and have been using the combo below this season. It has been the best overall backpacking brew method we have found. It is heavier than we would like, especially when coupled with a bag of beans. The major positives are that it does not take a bunch of room, you can make coffee for a crowd with a dedicated pour person, and it does make an exceptional cup.
The major drawback I see with this disposable French press in the backcountry is bulk. Weight is one issue, but bulk is as well. I know that my GF and I would go through, probably, six of these puny bags a day between breakfast, lunch and our cup when we arrive at camp. Drawback number two is that during fire season, or in certain parts of National Parks, you cannot have a campfires and would be required to pack all your stinky used bags out. The final drawback, Tex nailed it, “PREGROUND!â€
I did pass this link on to a good friend that is a commercial airline pilot. He is always complaining about his road coffee and has not been completely satisfied with the cleanup on the Aeropress I lent him. It will be interesting to see what he thinks.
