I think I have to read it just  few times to get it all. This is invaluable information! I didn't know there wasnt a set standard for evaluating espresso so it will be very interesting to see what your crew came up with Mark. its also too bad that Ken didnt choose to post his rebuttal on coffeegeek. I have all his books and admire the guy quite and it would have been great to see Ken participate in discussions here. I dont want to say anything bad about the man but it seems put offish that he didnt want to do so. I am really looking forward to the next article! dont take too long to publish it, bokay? --- Rick back to top Luca Moderator Joined: 27 Jan 2004 Posts: 2,658 Location: Melbourne, Australia Espresso: H: Maver W: FB-80 Grinder: H: Super Jolly W: Brasilia...

Thoughts from people with more experience than I have??

Is there any way your Crew can evaluate your list of coffee with a Sylvia espresso machine? Can a Sylvia pull a good shot of espresso with the "black cat" blend at it's pre set temp setting? What blend of Espresso should I stay away from with my Sylvia and or vice versa ? At what temp settings do the italians pull there shot's with there blend of coffee? Seing that the Sylvia is made in italy is it safe to say that the machine temp setting is set around there blend of espresso ?

But I just learned, by watching this video, how much water to run through my ECM Giotto portafilter to get the brew temperature right. The difference in my shots has been nothing short of amazing. I'm now consistently getting really beautiful, sweet espresso from several different blends (one of which I'd hated the day before). I'm sure I could dial each of the blends in even further, but my point for the moment is that you definitely can--and must--adjust the brew temperature on a heat-exchanger machine. back to top StarTzar Senior Member Joined: 1 Oct 2007 Posts: 5 Location: Gatineau Expertise: I live coffee Posted Mon Oct 1, 2007, 10:07am Subject: Re: Establishing an Espresso Evaluation Process by Mark Prince   I really do not care about the scores. I read what they have to say about the coffee and based on that, I choose to buy or not to buy the coffee. I make my own mind up as to what is or is not good tasting for me. Let's not forget the bottom line here,  it's all about the money and I don't care if it's Ken or Mark. back to top Elwood Senior Member Joined: 1 Oct 2007 Posts: 5 Location: Ottawa Posted Mon Oct 1, 2007, 11:03am Subject: Re: Establishing an Espresso Evaluation Process by Mark Prince   I just pulled a shot of lavazza oro(all this reading gave me a hunger for a espresso) whit my Sylvia...........my rating = 9.4 I also pulled a shot of Illy last night(again with my Sylvia) and gave it a 9.4 I will be tasting a "choco blend" tonight at the house of one of my Barista Bro, again with the Sylvia espresso machine,I don't no what rating he gave it which is cool because we will be able to talk about the blend of the choco, its taste, etcetera etcetera. It will be interesting to see his rating compared to mine,and if he or I like it or not. I will also bring my Lavazza oro to see what kind of rating he will give it.

I may not like what that one person likes).  Coffee is a very personal thing and everyone likes something different and considers "the best" to be different.  I personally like a darker roasted espresso, where as you may like a lighter roast....we therefore are going to score espressos very differently.  The only way I would agree with the score from a single decision maker is if I liked everything that person liked.   I would suggest having a panel of judges and using the average.  I say this because many people are going to use this score in the marketing and promotions of their espresso blends.  If someone got a bad score (lets say because it was to dark for you) it could be "used against them" on this or any other site talking about espresso scores.   Just my two scents.   RussP www.fratellocoffee.com www.slayerespresso.com back to top showing page 1 of 10 last page next page view previous topic | view next topic | view all topics Discussions > Articles > Columnist... > Establishing an...   updated topics   new posts   new unanswered     search   faq   sign up   Not Logged in: log in Discussions Quick Jump: Select Espresso Discussions --Espresso Machines --Lever Espresso Machines --Grinders - Espresso --Espresso Mods and Restorations --Espresso Blends --Questions and Answers --Latte Art and Etching --Barista Jams Around the World --General Discussion Coffee Discussions --Machines and Brewing Methods --Home Roasting Talk --Questions and Answers --General Discussion Columns, How-Tos, and Reviews --Holiday Gift List Feedback --CoffeeGeek Columnist Feedback --Detailed Review Feedback --Products First Look Feedback --Quickshot Review Feedback --Guide Article Feedback --How-To Article Feedback --CoffeeGeek Podcast Feedback Members Forum --Bug Reports and Suggestions --Buy, Sell and Trade --Retail Coffee Jobs Offered / Wanted Ads --Coffee Recipes --Cafe and Bean Reviews --CoffeeGeek Site Info and News --General Off Topics World Regional --United States West --United States Central --United States East --Western Canada --Eastern Canada --United Kingdom --Western Europe --Eastern Europe, Nordic Countries, and Russia --Central and South America --Australia, New Zealand and Asia Symbols: = New Posts since your last visit      = No New Posts since last visit     = Newest post Forum Rules: No profanity, illegal acts or personal attacks will be tolerated in these discussion boards.
