Subject: How much coffee has to go in LM double basket for Silvia ?
For my Rancilio Silvia I use the LM double basket, the "ridged" , not
the ridgeless one. My 58 mm tamper fits perfectly in it. (When I lower
the tamper in the empty basket, there is around 1mm space between the
top of the tamper and the edge of the basket).
Until a few days ago I filled the basket to the rim and leveled it at
that same height before tamping etc. However after reading the chapter
on dosing in David Schomer's book again, I checked the basket after
locking it and before brewing and there was a clear imprint of the screw
and the edge of the screen. So I leveled it a little below the edge of
the basket, just before the point where the screw imprint would appear,
but now I see that my pucks are rather wet after brewing.
What would be the best way ? Leveling to the edge, having already a
screw imprint before pulling or leveling a little bit lower, resulting
in a rather wet puck ?
Thanks for your opinions.
Ton

The only measuring I do for Silvia is when the beans go into the grinder. I
fill the basket, level with my finger, tamp lightly and polish. There is a
definite imprint of the center screw. More than that and I can't tighten
the PF as far as it should go. Less and I get too fast of a pour, with a
spot of blond crema in the center. Don't read too much. Coffee is kind of
like religion. Too much information can be confusing.

Ton -

I apologize because I know this is not exactly what you are looking
for, but maybe it will help a little anyway.

I have done some experimenting with the LM ridgeless double on my
Silvia (gotta be pretty similar to the ridged version, right?). I
pulled many samples using 15g, 16g, and 17g doses.

I think 17g is best. 16g is a very close second. (Didn't try 18g, but
it would not have fit). 15g was not quite enough coffee (blonded too
quickly).

This (17g) corresponds to the loose coffee being pretty even with the
top of the basket after distribution, and then around 1 mm short of
filling the basket after smoothing with my finger. After tamping (Reg
Barber), the top "edge" of the tamper base is a little less than 1mm
above the rim of the basket.

I get a definite impression of the screen screw, but not the ring
around the outer perimeter of the puck that you get if you get really
carried away with the dose.

Mmmmmmmm.
