My Porlex Mini grinder was intended for folk festivals, and possible post-retirement long-duration car touring. Brewing would have been Bialetti Brikka or Aeropress.
However: festival coffee in Australia is excellent; and retirement’s delights delayed the Grand Tour until the Covid pandemic, then prostate cancer, deflated that idea.
However I did have “own make” espresso (or billy-can) coffees in remote Arnhem Land in 2017 and 2019. Moka pot in the boat at sea is a rare treat.
