Yes, indeed this was a great article. I welcome the attention to coffee.
I was a little disappointed that percolated coffee wasn't covered. There are little 2 cup percolators that make outstanding coffee. They are made of aluminum and are fairly light. They can double as a water boiler for dehydrated meals/etc so in reality the setup is not much heavier than your regular pot for boiling water in, and is frankly lighter than many (not most) setups. A "Red Bull" style alcohol stove fits perfectly under one and water boils really fast in one with the lid closed. One of those "Ion" stoves works really well since it burns so slowly that it percolates the coffee rather than hard boiling it. For me it seemed to be the "perfect" setup so long as I was only boiling water for meals... until Java Juice came out.
I can post pictures if people want to see, but needless to say a percolator is a percolator. With a little modification it probably could be lighter (removing/replacing the handle specifically).
I can't say that I agree with the articles approach to the disposal of coffee grounds. I think the author expects this sort of response, however, so I don't feel bad about posting this. Coffee grounds are trash (as the article points out) and I pack all trash out... period. I agree that coffee grounds are biodegradable trash but so are a lot of other things. I carry coffee filters and line the basket of the percolator with them. The filters are light and dual use (can be used to "filter" floaties/etc out of water prior to treatment) Then I squeeze the water out of the grounds... carefully so as not to damage the filter, twist the top closed, and put the resulting package into two zip-lock baggies, one inside the other. These either go into the next campfire or are packed out and disposed of.
I am a Java Juice guy now pretty much. It's an expensive way to go but I am amazed at how good the coffee is and the form-factor is OUTSTANDING. :)
I'll add on edit that I don't think this thread needs to be classified as "Chaff". It's fair commentary and dialogue.
