• Yeah coffee is actually a pretty mental rabbit hole once you get into it, same as all the other fields you mentioned. There's a huge variety of flavours to be found in different origins of bean, different brew methods, different ways of pulling an espresso shot. The current methodical approach is quite young so new shit is always being discovered and experimented with, like the effects of water mineral content on coffee flavour, the fact that you can pull stupidly long shots if you grind using an EK43, and using vaccum-packed pre-dosed shots straight from the freezer. I've been working as a barista for a few years as a side thing and it's a shame there's so little money in it because it's pretty interesting once you get into it.

  • Cycling is a similar rabbit hole. Try and explain to a non cyclist why bikes can cost between £50–£12000 and you’ll get a similar incredulity/ ignorant anger.
