Topic: Upgrade priorities (8 msgs / 197 lines)
1) From: Robert Wachbroit
If you wanted to upgrade, what order would you do it -- roaster,  
grinder, or espresso machine/coffee maker? Yes, I know some people  
will say that all three are important and you should try to get the  
best you can in all three. But my question is about priorities, which  
should get more attention.
I can imagine one person saying, "The roaster, because no espresso  
machine can make good coffee out of badly roasted beans." On the  
other hand, I can imagine another person saying, "Roasting is more  
technique than equipment -- look at the wonderful roasts people on  
this list can do with the simplest of equipment. If you have extra  
cash, spend it on an espresso machine." And finally I can imagine a  
third person saying, "The grinder is the crucial link. But once you  
have a quality grinder, upgrading will result in only minor  
improvements."
As you can guess, I have been thinking about upgrading, but I am  
unsure how to go about it. In my own case, I have a Freshroast, an 8- 
year old Rocky grinder, and a Rancilio Rialto (internals very similar  
to Silvia) that has been PID'd. I would certainly be interested in  
hearing other's thoughts and experiences.

What are you hoping to accomplish or improve by upgrading? How old are your 
8yr old Rocky's burrs? (I recently replaced my Rocky's burrs after 2&1/2yrs 
and noticed an improvement in grind. Albeit relatively heavy use for all 
grinding duties.)

Grinder Burs, and then either a hottop, or custom (homebuilt) 1/2 - 1 lb 
roaster.

The stains become a warning.

Absolutely. I know this doesn't fly in the face of those saying the grinder=

The burrs are 8 years old. Although they are probably a little worn,  
I expect the wear is even. I thought that as long as the grinder  
could give me a fine enough grind -- as determined by being able to  
draw a 25-second espresso shot -- the burrs were OK. Is that wrong?

Robert,
     If the burrs are worn, they are dull and will produce dust with  
your grind.  It doesn't matter if they wear evenly or not.  It is the  
sharpness that counts.  Open the Rocky up and feel the burrs.   If  
the edges don't feel sharp, like with a cutting edge, put buying new  
burrs on your gotta list.

IMO yes, that is wrong. Worn burrs will grind less evenly producing more 
dust. Less even grind equals less even extraction. (any brewing method) Wear 
and grind change would be gradual over time and shot technique changed along 
the way without even realizing it. Just pulling a shot of your target volume 
in 25sec doesn't mean the shot is all it "could" be.

8 years old!?!?!?
yeah - it's time to replace the burrs.
you're going to get uneven grinding, as mentioned. this is going to
create poor extraction, again as mentioned. in addition, it's going to
result in uneven particle shape, more "crushing" than sheering and
higher heat imparted to the grounds.
new burrs needed now!
heh
