So what? You think. Hasn't everyone? Nope, not me. Not until now.
The reasons why? Well, I buy mostly green beans, and the roasted ones I have bought have so far been other brands. From time to time it is fun and interesting to compare homeroasted with commercial coffee. If for no other reason, at least it is good for one's personal taste reference... and I suppose Illy really ought to be a part of it.
This particular Illy can says "100% Arabica". It also says "caffè in grani" (whole beans), best before january 2007 (!) and "avoid any improper use of the can". Hope I don't use it improperly by having it beside the computer, then...
Anyways, here is the verdict of the Partille jury. Don't expect any standard coffee language, I am not that well educated yet.
Actually, I am positively surprised. This is better than several other commercial blends I have tried. Good crema (for a 100% arabica blend that is), good pour, easy to do both ristrettos and espressos. A good balanced taste with a strong but not sharp start. It does have what I would recognise as a "Robusta finish" though. Muffled and somewhat murky or moldy. I suppose that some percentage of those 100% arabicas was rather cheap?
Illy compared to home roasted? That is a bit like asking "how much is a brown horse?", I guess, but to tell you the truth I can't wait until I get out on the balcony with the heat gun again.
What would I miss from the homeroasts if someone forced me to use only Illy? All that taste, brother! The adventure, sister! Spices, flowers, softness, strength, good body, acidity... Still, for espresso I like this Illy more than all the other cheap/mid priced espresso blends I have tried, save one (molinero? molinari? In any case it was a yellow/gold colored bag). Illy works fine with milk too.
