Is this something done day to day as beans go stale? Surely that would waste a lot of shots in fine tuning
I try to get different beans from SQM, a kilo every month (I have a Patreon discount code so it comes 10% cheaper) and don't mix different types of beans in the hopper. As a result, last week of a particular bag the pressure on the hopper declines (as I can't/won't top-up with the other type of bean - also maybe the beans have gotten slightly stale over the past 3 weeks etc) I find the shots start running a little bit quicker, maybe because the grinder adjustment changes without the consistent hopper-pressure. So I have to adjust for finer and finer. Next bag, it's back to my original setting (of 0.5) to start dialling in.
The grinder is an Eureka Mignon Specialita (comes with a "large" 55mm burr set). Maybe I should consider putting the next bag inside the hopper but preventing any mix-up with an oven liner or something. Wouldn't be the end of the world, but mixing would lead to an inconsistent grind and a bad couple of shots before it's settled.
Haven't bought the actual machine yet but potentially the same again for grinder if its needed to get 'drinkable' espresso. I'm not a massive fan of the idea of grinding beans to dose every morning
