Dialing in your grinder every day ?

Grinders are one of the keys to exceptional espresso. Discuss them here.

Hi All,

I am new to espresso , I usually make 2 milk drinks and 1 espresso every day. When i got a new batch of beans i usually dial in the grinder for the perfect shot, however the next day the shot is usually slower and i have to dial the grinder again.

do you dial your grinder everyday ? or what is your routine ?

Once I have dialed in a particular coffee, I typically only need to make minor tweaks to dose or grind setting as that batch of coffee ages post-roast. Typically, I might need to grind a touch finer or slightly increase dose as the coffee beans age. If there is a problem with taste, or if I did not quite dial in on the first day, then I will make bigger adjustments until I fix the problem. If I still cannot fix the problem, I use the remainder of that coffee for pour-over brew. Lastly, if I just want to try something different, like changing the brew ratio, then I will re-dial in. Otherwise, no.

I once talked to a barista at a local cafe whose grinder is located right next to the front door. She told me that it is very difficult to stay dialed-in during the day because of the humidity changes of the beans.

Yes - as coffee ages and humidity changes, your grind settings will have to be adjusted.

Anyway, one thing I found interesting/curious about your experience is that you're saying the next day you're having a "slower" shot?

Usually the opposite happens (considering all the other variables - humidity, temperature, dose - don't change). As days go by, if you keep the same grind settings, the shots will run faster. And therefore you'll need to grind finer.

I find that curious as well, which begs the question...how sure are you that you were really dialed in? It's easy to have a one off great shot while trying to dial in when starting out. What you need to really be dialed in is consistency...or maybe better said...repeatability.

What grinder do you use?
The beans from a roastery or bagged beans?

I had the same issue when I just started with the Breville Barista Express's integrated grinder. That grinder has few grams (!) of retention, and I had no idea I needed to purge it every morning, so my first shot of the day was full of stale grounds from yesterday. When I figured that out and started purging, things somewhat improved.

However, I was also grinding using the time based buttons on the grinder, and I noticed that for some shots the grinder would retain more, and then would drop that extra retained amount on the next shot. So I got myself a scale and started single dosing, weighing the grinder input and output, using the manual option, and things improved a bit more.

In the end, I got frustrated with the grinder and wasted coffee, and upgraded to a low-retention single-dosing grinder.

I find that if I use coffee that is too fresh (like 5 days), I sometimes have to go coarser as it ages. Once its reached its peak on around day 8, my grind rarely changes with my pharos.

This is common for most grinders. I was tweaking daily with my Mahlkonig K30, with my Monolith Conical it's maybe once a week

My Monolith Conical. Only a slight change when I open up a new 2.2 lb bag. If the humidity changes drastically in the house, I might make a slight change. Not very much, and not to often.
