Subject: MYPRESSI serious question - Why is it inferior to better machines (like Silvia)?
 

Hi Team,

Please don't take it as a stupid question.  Clearly the MyPressi IS inferior, but this relative newbie would like the nuts and bolts answer of WHY.  I've spent the past few months experimenting and pulling shots with Mypressi (using a Rocky grinder) and I've finally accepted that at its best it will never be comparable to what I get when I walk into Stumptown.

I'm saving money to get a Silvia, but in the meantime, why exactly is it not as good?  Hot water is being expressed through a showerhead into a correctly tamped puck - when this happens on better machines, what's the difference?

Thanks so much for satisfying this passionate newbie's curiosity.

It is the Rocky that is inferior - not the Mypressi.
If you had a better grinder (and maybe better beans?) then you'd get better results.  

Dan Kehn made a video showing the Mypressi comparing favorably to a LaMarzocco FB80.  CLICK
(Search for the comments on HB - blind tasters enjoyed both shots and couldn't pick a favorite)

+1 - Rocky isn't the worst grinder in the world....but there's MUCH better out there.  I'd argue that the MyPressi is actually quite superior to a Silvia, it's simply less convenient and more expensive per-shot to operate. The MyPressi, assuming you can heat your water to the right temperature, has as stable a temperature as you provide, and very even, reliable pressure via the N2O cartridges.  Silvia has temp stability all over the place, and, in the case of old models (like mine was) without the adjustable OPV, can build more pressure than desired.  

Where Silvia wins is it doesn't cost $0.70 in electric every time you pull a shot like the consumer price on N20, states don't ban or limit the sale of silvia shots like many do with N2O, and it heats its own water without you holding a thermometer in a tea kettle or microwave.  If you don't pull shots often though, the MyPressi is far cheaper overall though.

I have 2 of them.
Use at work everyday.
Use Mazzer Super Jolly grinder...
It's just incredible...My shot isn't as good as Home with the quickmill alexia but it's better then
any coffeehouse within walking distance of work.

Buddy ground some beans with his Rocky..and the shot came out sputtering..pretty bad...

I think the grinder plays a huge role with the Pressi results.

Cheers

8/10 for quality of shot.

p.s. Owner is great guy at Pressi..... He's sending my buddy replacements at no cost for two Pressi's that were ordered during the christmas rush "and lost".

p.p.s. If I had to do it over, I'd buy this first as a newbie..and use with a bodum milk frother for lattes. Save up for years and then blow a few grand on a decent machine.

Cheers

I love my Twist.  It makes good espresso at home with a proper grinder and when I travel with a hand grinder.  If you're getting "inferior" results, the problem isn't with the Twist (unless your's is broken in some way).

I pulled an indescribably good shot on my third try with the Twist (God shot? Maybe. I don't like the term but I don't have any other way describing something so wonderful and memorable).  It was luck and a good grinder, and not to be repeated, but there isn't a limit to the Twists is potentially capable of on at least a one off basis.

+1 for the Twist!

Devil's advocate here:

"It makes good espresso at home with a proper grinder and when I travel with a hand grinder.  If you're getting "inferior" results, the problem isn't with the Twist (unless your's is broken in some way)."


A problem could exist with your "O rings",faulty cartridges, etc. etc. and as all espresso enthusiasts know..... grinders are everything. They change the results of a shot.

There is a huge difference between pulling a shot using ground beans from a Mazzer vs Solis.

That said, fresh roasted high quality beans will make or break your Pressi results.

ps. I get about 4 shots or pulls per cartridge.  Based on what I paid for the cartridges, it costs me .20 cents per shot (2 drinks day x 365 days / $146.00 year)

That's pretty good considering the machine is below $200.00 and gives such high quality shots.

Dear Mad Tamper and pravspresso,

NB: One can buy N2O cartridges online for a total cost of $0.41 per cartridge (incl. shipping) without looking too hard.  This translates to 8 cents per shot (I invariably get 5 shots per cartridge and, by reports online, most other users do, too).

Dear Javerich,

All of the feedback regarding grinders is accurate but perhaps your question could be answered a little more specifically:

You are comparing your Mypressi to Stumptown.  I have never been to Stumptown but they must operate along similar lines to some of the premier coffeehouses which I have visited.  As I understand it, they dial in their high-end machines with regard to temperature, perhaps pressure profiling, and shot duration all on a daily basis, making those changes that are required by changes in weather.  Perhaps the grind is 'tweaked' up or down on a daily basis, as well.  You cannot begin to compete with this level of technological expertise with your Mypressi.  If you compare Mypressi to Starbucks or Dunkin Donuts, Mypressi is certainly to come out a winner.
You imply that Mypressi is inferior to a Sylvia, but you also imply that you do not own a Silvia.  To what amateur-operated machine are you comparing the Mypressi, if not to Stumptown only?
In an effort to be helpful rather than solely critical, may I suggest that the best-known problem with the Mypressi is its tendency to channel.  If you are a newby, take some time to read up on channeling.  The Mypressi is especially prone to edge channeling, specifically if the roast is old.  Mypressi makes it easy to use it as a 'naked portafilter' by leaving off the spout attachment.  It is easy to watch the stream and compare it to pictures published on Home Barista and other web sites.  The easiest fixes for your shot quality is to 1) buy some verifiable freshly-roasted beans and grind them soon after purchase and infuse them within 1 or 2 minutes of grinding.  This tends to eliminate edge channeling.  Use the Weiss Declumping Technique (WDT) prior to tamping (google it).  A more involved fix is to purchase a good quality 53 mm tamper.  Better yet, a 53.5 mm tamper.  If you find one of the latter, tell me.  Also, time your infusions with a timer.  If your time for infusion suddenly shortens by 2 or 3 seconds without a change in grind size, chances are are inapparent channeling (or unnoticed channeling) has taken place during that infusion.
It sounds as if you are on a learning curve (like me) and that your tool of the moment happens to be a Mypressi.  Don't blame your tools.

Hope this helps and doesn't rankle too much,

B

Everyone can buy cartridges online cheap.

I did a combo buy with a buddy and bought Whip It versions in bulk.

I typed in N20 cartridges in Google: this took me 2 min. to find.

Click Here (www.ebay.com)


300/$93.00 = .31 CENTS per cartridge "cheaper ones listed."

4 shots which is sorta what I get divided by / .31 cents per cartridge = AWESOME

just to whip the dead horse a bit more, your grinder is the weak spot in your setup. If I were you, first upgrade the grinder then save your money and if you STILL want a "real" espresso machine, skip the SBDU class all together and move to a machine like the CC1 as a minimum. It has PID temp control for brewing and a thermoblock for steaming so you are not playing the up and down temp game. For the same price you can pick up a used HX machine and likely as not, it would be the end of your quest for a "better" machine for a very long time.

As a side note, please do not use every possible space in your topic heading, when someone replies to you, the board software adds RE: to the header then it is too long and we, those of us replying to you, are forced to edit your header as it is then too long.
