Mostly OT - but the major problem with espresso based coffee quality on board is not actually the beans used/sealed nespresso capsules, but the water they use to make it. It's filtered and quite treated, so not very nice. Not much mineral content. It's completely plumbed into the aircraft system, before anyone asks them to pour bottled water into the coffee machine :P

Now that instant Y stuff...well...let's simply call that a "caffeine dispenser", not a drink...!
