When I load up my Mazzer with new beans, I must reset
my dial near to the factory default mark. Each day
these beans in the hopper rest, they take about 2 seconds
longer to extract than the day before. Therefore I must
nudge the dial (finer) each day a little under half a notch
per day.
I've got it down to where I nudge the dial ever so slightly
each day before grinding, and my shots come out right on the
mark. The only problem is when the batch runs dry and I have
to start the process over. But then all new beans must be
dialed in. Such is life.
I'm just curious what might actually be going on here. Must
I grind a little finer each day because the beans are growing
harder or softer each day? Or because they picked up more
moisture from the air, or dried out more? Or what? I find
it hard to imagine if something growing harder or softer
would necessitate an increase or decrease in fineness.
Normally I would be satisfied just to perform my routine
and move on, however my curiosity won't seem to go away.
