I think there definitely a lot of marketing in tasting notes. You could call something citrus, or even better lemon, but yuzu sounds more exotic again.
It’s like any food menu that doesn’t have roast lamb, it has slow roasted lamb. Cheese & Onion crisps are mature cheddar cheese and caramelised onion.
However, just to contradict myself. I guess most roasters would have a coffee that could come under the red berries description, but they won’t all taste the same so describing one as cranberry and one as redcurrant might just be so there’s differentiation between roasters.
I personally go for a general style of coffee, usually avoiding anything with too many chocolate/nut flavours but won’t get too hung up on trying to find a specific flavour.
