Topic: Starbucks espresso vs. mine (28 msgs / 595 lines)
1) From: Paul Goelz
OK, why can I get a better shot form Starbucks than I can at home?  This 
has bugged me for a long time.  Mine are bitter and Starbucks shots are not.
I have tried using Starbucks espresso blend (same as they use) ground by 
them and I still get a similarly bitter shot at home.
Equipment is an Estro Vapore.  I allow it to warm up with the portafilter 
attached.  I have tried tamping and not tamping.  It always comes out 
bitter.  Not awful, but more bitter than I like.
The people at Starbucks say that the water is the key and that they filter 
it eight times.  Hmmmm....  so I went out and bought a Brita pitcher 
filter.  I think it made a difference but not much.
Any other suggestions?

Paul, It doesn't make sense does it?  Any home barista ought to be able to
match, if not exceed, Starbucks quality.  Three things that I know make for
bitter espresso, RO water, over extraction, water too hot.  Dan
<Snip>
not.

Hi Paul - long time between posts!   You might look at water temperature. If
your water isn't up to standard you will get some brackish espresso.  When I
went from my steam toy to the La Pavoni I couldn't believe the difference in
quality. Time to pull the shot will also have a bearing on the outcome.

Quoting Paul Goelz :
<Snip>
Try a few shots with some completely different (eg. bottled) water.  
Try pulling your cup out from under the portafilter after 25 seconds 
and see if that cup tastes good.  Try running the machine with a 
styrofoam cup in place of the portafilter and measure the temperature 
of the water in the cup (should be 197-203 F).

extraction, water too hot.  Dan
Also a dirty group head.
BTW why does RO water cause bitter espresso? I've never noticed this, and my
domestic drinking supply has an RO unit after the softener.

I had some friend up here a couple of weeks ago who were blown away by my
shots, so much so that they had four each and remarked when they left for
Hood River that mune far surpassed Starbucks in Santa Monica!
yes!!

Because it can be acidic.  RO water makes for a very bitter cup of tea, just
try it.  I treat the RO water with calcite to neutralize the acid and add
some hardness for flavor.  Helps a lot.  Dan

I normally do the steamed milk with the portafilter loaded and in 
place.  Then I do the espresso.  It may be that the water is too hot for a 
while... but I think I have tried it both ways.  I'll try again.
I hate Starbucks coffee but I actually like their espresso.

The machine should be fairly clean.  I ran a tankful of Urnex and two rinse

I'm still here and lurking.  But I've been happy with my coffee lately 
(CRLM) and haven't had anything to say.  But with winter, I started making 
cappucinos again and the espresso thing bugs me.
I have a hard time controlling the time of the shot.  Starbucks espresso 
grind is finer than I can do in my Solis and it still takes maybe 15 
seconds for a double.  I'll try tamping heavier next time and see if I can 
slow it down a bit.
Refresh me.... is it 20 seconds for 1 oz or 2 oz?

Between 20&30 sec 1oz & 2oz using different PF and amount of grind of
course. I target 26sec for mine, have digital timer sitting on top of Miss
Silvia (SS timer of course).
You NEED a decent grinder if you expect to get decent shots!

I've been using domestic RO treatment for 8 or 9 years. I buy very high
quality teas as well as coffees. Bitterness is not an issue. Maybe my
domestic RO treatment is not as efficient as that used for commercial RO
water. I dunno - but certainly your assertion and my experience don't match.
It's not that I disbelieve you - I just don't seem to experience what you
say. I use Brita jugs when I'm working away from home and I don't recall the
results being better either. Equally, (unfiltered water) + (tea or coffee) =
Yukkk!
I'm certainly interested to try the calcite experiment though, since my
situation may be marginally improved by it. Where do you buy it?
BTW, what is the source of the acidity?
Phil.

14) From: Dan Bollinger
I believe, but I'm not sure, the RO acidity problem is related to the input
water and its dissolved gases. Not all RO water is acidic. I know one person
who's RO water was 7.2   Mine is 6.0    See if you can get a small amount to
play with from Culligan or other water softener outlets. It isn't expensive,
but you have to buy a large bag.  Dan

I get a 17 second 1 or 2 ounce from the Solis Master, but I used to aim for
as close to 20 seconds as I could with the La Pavoni. I tended to over tamp
that beastie but it produced wonderful brew.

16) From: Spencer W. Thomas
RO water left exposed to the atmosphere will absorb carbon dioxide, and 
will become acidic. If it's never been exposed to the atmosphere, it 
won't have had time to acidify.

Hmmm...   Mine is acidic out of the RO tap.  Is it possible that my well
water has dissolved CO2 in it?  Dan

Paul,
I would try grinding a little less fine and give it a nice even tamp.  How
is your grinder?  I didn't know what a good shot was until I got a good burr
grinder.  The grinder is the key as well as the advice that Dan just gave.

I use the Solis sold by Starbucks.  I have re-calibrated it to grind as 
fine as possible without the burrs hitting.  But it still does not grind as 
fine as Starbucks does.  I have tried using all sorts of tamps and grinds 
from drip to as fine as it goes, and they always turn out bitter.
I used to thing it was my blend and/or roast level until I tried some of 
the stuff Starbucks uses.  While I do like the Starbucks blend better than 
mine it is still bitter when I pull a shot.

Your grinder could well be the problem.  If the burrs ever touched, you 
could be producing a lot of dust.  There has been considerable 
discussion of how the Solis does not have a rigid enough frame to hold 
the burrs close together without touching during grinding.

Well, that doesn't apply here.  I had Starbuck grind the beans and the 
grind looks pretty good.  The only difference between what they brew and 
what they sold me was that it wasn't ground in the same grinder.
I have to note that once in a very great while I get a good shot.  It has 
been maybe six months since the last one, though.  I used to use regular 
cinnamon to city roasted CRLM because I only have one good grinder and we 
drink a lot more coffee than I drink espresso.  But I think that if I buy 
1/4 pound of *$ espresso grind, I can go through it before it stales too 
badly.

I'd agree. I was amazed to discover, once I replaced my Solis with a Mazzer
Mini, that I no longer needed to add sugar to my espresso. If you can swing
it, get a Rocky or better. If you can't, start putting money away now for a
future purchase. You'll certainly notice a difference, and likely not need
to replace your grinder any time in the near future, if ever. I'm quite
confident my Mazzer will outlast me.

Speaking of grinders, if it hasn't been cleaned out lately, that'll make a 
difference. I keep a grinder at work, and blast it out with compressed air, 
followed by a quick scrub every other week, and it makes a really noticeable 
difference every time.

27) From: Stephen Carey
Hello Paul,
One often overlooked area is to de-scale the machine.  Minerals in the water
build up in the machine over time and it can add to a bitter taste.  Try
cleaning it with non pulp lemon juice (as in fill the tank with a solution
and run it through all parts of the machine) or buy a de-scaling solution.
Also, and I know many will disagree, but I don't worry so much about the
time of the shot.  I look for the color and layers.  Go for a good crema,
mostly body and just a small dark heart on the bottom of the shot.  I use a
*$ barista (pretty much a Vapore) and get great tasting shots regularly.

Any idea what proportions?  Or what commercial de-scaling solution is 
recommended?  I did run a tankful of Urnex through it but that is a 
detergent and not a de-scaler, right?

Sounds like we have the same machine.  I bought mine from Starbucks back 
before they put the Starbucks name on it.  Other than the shape of the 
portafilter handle, I think they are identical.  There was a cool deep 
garnet red one I saw a month ago in our local Starbucks.  Darn near bought 
it on the spot!  My goodness, it was gorgeous!
