I think Luca and Miguel are exactly right. Specific instructions are actually worse than worthless, they can be downright harmful! Clearly the participants
here may/will/should (if they stop to think about it) that what is "right" for an e61 HX machine may not be the same with a saturated group or for a lever model . . . let alone for different e61 machines, or different dual boiler models . . . let alone for
personal preferences! It's much like winemakers including suggested food recommendations on the back labels of their wines, or suggested drinking windows . . . taste is personal, and while one person may like their Cabernet Sauvignon to be 15 years old, another may prefer it at age 4 -- and it varies with each vintage. Wine is an agricultural crop, same as coffee, and no one size fits all.
The closest you could possibly get is something along the lines of what Dan wrote above:
HB wrote:Something along the lines of "cool / medium / medium-hot / hot" for brew temperature and "downdose/ regular dose / updose" are about as good as it gets.
And there will be exceptions to even that!
Cheers,
