There’s mitigation options but they all have their limitations / issues:
- caffeine pill to wake up, then coffee for the taste / comfort
- brew in the evening (at home when flying out, at the hotel when flying back in) and store in a quality insulated mug, using a zojirushi, freshly brewed coffee in yields too-hot-to-drink 10 hours later (but that’s nothing a travel mug and waiting a few minutes can’t solve).
- there’s also the flash-frozen thing which Hoffmann showed and seemed happy about, but I think it needs to remain frozen (it can’t be stored at room temp) which is not super convenient when travelling unless you have good logistics (or regularly travel back and forth so could have stashes at critical locations)
- similar situation (travel between known location), do better recon and find an acceptable coffee shop on the way (then hope they don’t go out of business)
