In reply to john morrissey:
I have a sliding scale of portable coffee making equipment: at the lightest end is a GSI filter that clips onto a cup, weighs a few grams and makes surprisingly acceptable coffee, bit of a hassle to clean if water is scarce; an aeropress, pretty bomber, once used one for about 6 months round S America; I used to have a Handpresso, heavy, made ok espresso, the pump failed but only after 4-5yrs.
I have just acquired a minipresso Nespresso version. I don’t generally agree with the waste of capsules for home use, but I found that after even a few days tramping, pre-ground coffee starting tasting stale, and cleaning grinds could be difficult with limited water, the sealed capsules solve both issues, if I can spare the weight of the Minipresso.
