James Hoffman would disagree with you there
He certainly would, but those are the destructions from Aeropress, at least they used to be. I use 85C water, extremely fine grind (finer than espresso), lighter roast, same coffee:water ratio as James, stir before inserting the plunger and brew for four minutes. I've yet to try this at 36,000ft but that's now on my to-do list - in the interests of science, of course
