Whilst I appreciate that taste is subjective, and there’s been some great discussion as to flavour notes, I’m curious why not many roasters provide guide recipes - for example: Espresso, 18g in, 40g out in 35secs at 93c.
I mean, whilst there will be variance, it could at least offer a direction as to where the expected ‘flavours’ hang out, rather than everyone starting with a 30s rule and not much beyond that other than personal preference. Sure, flow/pressure control etc. is beyond the scope, but I would imagine that most people interested in speciality coffee are using equipment that should be able to get somewhere in the same region ?
Are there any UK roasters that do this ?
