I don’t know about you but I can’t wait for that lovely rubber scented air to be forced through my lovely coffee grounds and into a frothy bit of wonderment. Portable espresso has one problem, the water temperature. When someone solves this I think we will be all set, but until then I’d rather just stick to iced coffee on the go. Although this gadget does come in at 180 dollars for your fixed gear friends. Good idea, interesting and reusable source of pressure. Bad Idea finding water at 200 degrees F in the middle of the woods. SlipperyBrick.com.
