Intro:
The Rancilio
Consumer line-up
is a lot like a prosumer machine in construction, appearance and shot
quality.
One difference is
the single
boiler found in the
Rancilio.
The practical difference is that you cannot steam while your
espresso is pouring and you will need to wait for around 25 seconds for
the machine to indicate that it is ready to steam. The
'prosumer' machines have heat exchangers (aka HX) that provide
on-demand steam.
There is a lot of talk about how 'finicky' the Silvia is.
While
the Silvia is not a toy, I find it perfectly suited for home users.
It will
take some trial and error to get up and running. You will
have to maintain the unit by proper cleaning. But the reward
will be espresso drinks that are superior to most of what you get in
the coffee shop.
A
Silvia
espresso machine a Rocky grinder sell for under $800.00 -- much
less than the Prosumer HX products.

Silvia
and Rocky:
1) The
Silvia is well constructed, with brass boiler, brass lines
and chromed
brass brewing head all which help to maintain temperature and heat
distribution for
the perfect espresso. One
important point here; Get a good grinder! Your
Silvia will
be severely handicapped with a sub par grinder. At the very
least
buy a Solis Maestro (regularly found on ebay for under $100).
Silvia is a compact machine at 13.25"H
x 11.25"W x 9.25"D.
2) The
Rocky (I recommend the doserless version) is an excellent
product. With 55 settings - you should be able to dial in the
right grind for espresso. The portafilter holder is nicely
designed to hold the portafilter - hands free. Size: 4.5"W
x 9.5"D x 13.75"H
ISSUES:
Rancilio includes a plastic
tamper with Ms. Silvia (tamper is used to compact the
coffee grounds).
This is probably responsible for more bad espresso shots and more
frustration than anything else. Make life easy and get a decent tamper
- I sell aluminum tampers starting at $18.99. accessory page
Read the instructions before
you plug it in. They are written by
Italians and have a some weird translations. They do
not help you get good espresso -- they do help you power up without
destroying your new $500 espresso machine or burning yourself.
Temperature surfing made easy.
Home espresso machines do not have stable temp's like 220V
commercial machines. In fact, the Silvia is factory set to
make
the water hotter than is ideal for espresso. There is an easy
way
to 'surf' your machine into a sweet spot. When your Silvia
has
heated up and indicates it is ready to make espresso the water is going
to be a bit too hot. The best way to get that temp into the
zone
is to begin by frothing your milk - thus adding fresh water from the
reservoir into the hot boiler (if you do not want milk, just shoot
steam into a pitcher or cup for 30 seconds). While the
machine
heats back up, you can grind your beans and tamp. Just when the machine
indicates it is ready again the water should be perfectly heated.
Make your shot now!
You can use all of the stock parts
that come with your machine but
there are some items that can improve your results right away.
For instance, the double
filter basket
is a bit small. I inserted a La Marzocco standard dbl. filter
and
found it worked better with the extra volume accessory page
or upgrade the entire
portafilter to a Marzocco or bottomless/naked, but I found the stock PF
to be sufficient. The steam wand is visually underwhelming
but
works well - actually Silvia has a lot of steam.
Hot
water for tea or an 'Americano' is dispensed via is the
steam wand and determined by
which of the rocker switches you have engaged. After using it
for
water you need to release the left over water in the tube before
steaming. I'd prefer to have a dedicated water dispenser - in
case anyone at Rancilio is reading this. Be careful not to
shoot
a bunch of hot water into your milk.
Step by
Step:
If you follow the these steps you can get great results
fairly quickly.
Step 1.
Grind to
fill filter basket a little over filled.
Use
the double filter basket. Start with the grind.
I found
that Rocky made an ideal grind set on #12. Your beans may
need a
click up or down. So -- If you dial in at #12 and tamp well
but
the shot is fast and weak... try #11 for a finer grind.
Conversely if you are using oily beans you might get a very
slow
shot and bitter thick espresso... try #13 or #14.
Step 2.
Level,
Tamp and Load.
Use a good tamper to compact the grounds. If you are new to
tamping read this - how
to tamp guide -
Lift the tamped PF into the Silvia's Group Head and
rotate
from your
left to right. The portafilter will turn past the 90 degree
point. It should be tight but if it's a struggle you probably
have too much coffee in the PF (dump it out and start with new
grounds). If you cannot lift the PF into Silvia's Group Head
you
have too much coffee in the PF.
Step 3.
Making
the shot.
The Rancilio Silvia Control Panel is strictly classic, old school.
No temp gage or pressure gage (if you want to really geek out
you can look into PID conversion).
Operation
is pretty simple.
(Assuming you have switched the power switch to on &
waited apx 15 minutes for the
'ready indicator' to de-illuminate - to some people it's a
little
counter-intuitive that the light IS
illuminated when the machine IS NOT
ready)
Follow the instructions for Temperature surfing
At this point switch the top rocker indicated by a line
art of a coffee
cup - the round orange light will illuminate and the pump will engage
pushing hot water through coffee grounds -- extracting the espresso.
Within the first 5 seconds you should be getting
at least drips. If you don't get anything after 10 seconds
you
should switch the rocker to off (pressure will release in drip pan) and
start over with a coarser grind. If you get a fast pale
frothy
shot you need to adjust for finer grind. A good shot will
have
auburn 'crema' over black strong espresso. Extraction time
for a
double filter can be 20 or 25 seconds - maybe a bit longer.
Watch the flow of espresso and if you see a blond color or
bubbles in the flow you should stop the shot. Switch the
espresso rocker switch off to stop the extraction.

Step 4.
Steaming
milk for a cappuccino.
To make the foamy topping for a cappuccino or latte you will fill a
pitcher 1/4 to 1/3 with milk. When the indicator light turns
off
you are
ready to steam milk. Switch the 'steaming' rocker switch on
&
the ready indicator will now illuminate (open the valve a bit to push
out any water in the wand and close it back). Use a 12oz to
20oz.
stainless steel
pitcher - preferably with a thermometer accessory page.
Submerge the steaming wand
tip (barely) into the milk before you begin turning the
steaming
knob
counter-clockwise. Turn it open a bit and try to get a mellow
whishhing sound rather than a strong whooshing sound - if that makes
any sense. As you steam the milk it will expand and rise.
Slowly
lower the pitcher as the milk rises to keep the tip just submerged. At
around 100F you should stop lowering the pitcher and allow the tip to
submerge more deeply. The temp will increase more quickly
from
100F to 150F. If your milk gets much over 150F it will
probably
taste terrible and be inconsistent. 'Micro foam' is sweet
tasting
and has a smooth texture - It will pour evenly from your pitcher.
Finally pour the foamy milk over the espresso for your espresso!
