Subject: different grinder setting for L/D beans?
 

I have Rossi RR45 grinder, (new blades 3 weeks) and I noticed that if I grind darker roast, I must loosen the burrs by 2 clicks.

If I use the dark roast setting for lighter roast, water runs through the filter in  few seconds, resulting in whitish, sink shot.

If I set the burrs to light roast and grind dark roast, the shot won't go through filter, water won't come out for 20 seconds...

Is that normal, such big re-adjustment?  Normally it would not bother me, but since I have few different roasts, if I forget, shot goes in the sink...

TIA

It doesn't surprise me at all that you need to make that sort of adjustment.  Now, I have not used that grinder myself, but I understand that it has 80 steps; I assume that should mean they are very small.

The reason it varies so much is the darker you roast a coffee, the easier it extracts.  The bean gets softer, the water content lessens, the oil comes to the surface.  All of these cause it to be much more dense.

Are you dosing by weight or volume?  If you are doing volume then it would most certainly mean you are going to make an even larger grinder adjustment because more coffee, by weight, is fitting into the basket.

Hopefully someone else with this grinder will chime in with their experience, but I suspect what you are encountering is quite normal.

Thank you Chris, your explanation makes sense....
Interesting that such "fine" adjustment, of 2! clicks that are really "tiny" change the results of a shot...
I am dosing by weight, 16-17g and try to tamp with same force...Need to be more constant with my roasting...
cheers

The 45 is a good grinder, some have 40 steps and some have 80, it just depends on which you have.
Adjusting for different coffee? I am wondering why you are not adjusting for the same coffee on different days! As coffee ages, the required grind changes. It should not be a shock to need to make grind changes when making  a radical changes such as completely different beans in a totally different place in the age cycle.

Yes this is normal.

Just checked and it's 40 step setting, kind of useless, "0" is on "15" and dark roast is "7", light "9",  got my own markings, really hacked grinder, stripped down, no doser, no hopper,, but works great.

Thanks for conformation, it all makes sense, the only bummer is that a lot doubles go down the drain, as I didn't yet master my popcorn stovetop popper and my roasts vary, but it's getting there...
cheers

You could update the 80 step ring. There are a couple suppliers in Aus, probably some in Europe also. Click Here (www.aetcoffeeparts.com.au) You need to update the pin also.

Try different hours!!  Spoke to a top local barista and asked if he tweaked the grind much.  He said:  naw, only once an hour.   my kitchen is 60f and 50% in the morn and 85f and 12% at 5.  We drink ice coffee at five.....  

Even when I pick up a new pound of my fav bean from a local roaster,  I prepare for the necessary dial in.  I thought that's one of the reasons why we go through this?

It depends on how often you make coffee. Most here only make it once a day, mostly in the morning. If you were to make it all day, then you need to adjust constantly, yes I do.

I have been at this game for...... a while, (take a look at my info to the left) been there, done that :D
