Well, I sure did. I've heard it before that the only way to make good espresso with the less expensive machines is to use imported ground coffee.
I think the net is full of people who believe stuff earnestly and don't save time or effort telling others what they think.
My opinion, and it's worth every cent you pay for it, is that it doesn't matter what they say. The best coffee is the coffee you like made the way you like. That's the reason people like that reporter will often get "shocked" how good some other person's coffee was when it wasn't their favorite brand/process. If we paid more attention to the flavor than the prices, we'd be happier with several different processes and coffees. I certainly have enjoyed espressos made in all kinds of machines by my friends, some of which buy pre-ground imported Italian coffee, some of them grind their own beans and a few of them roast then grind their beans at home. The kind of coffee seems to make more of a difference then whatever you are using to grind it.
It's highly unlikely that the perfect uniform grind is that important, for example, because I've bought both Cafe Bustelo and Illy and their grind is not perfectly uniform either. It's highly unlikely that a metal tamp is important either -- I'm willing to bet that for the forces used to tamp down espresso in the filter, a good sturdy plastic, wooden or metal tamp will do. If he ever used a flimsy metal tamp, he'd not be telling others it's important to be metal, but that it not be flimsy. And really, it's not like one is putting hundreds of pounds per square inch in there, the tamp has to be truly flimsy to be worthless, I have the impression it's more either ignorance, superstition or snob appeal that he's displaying, maybe a combination.
The video is not much better. He goes to great lengths to heat up everything, including the portafilter. Well, while it may be true that one needs to brew coffee at a particular temperature, I have no doubts that the espresso maker he has can produce those temperatures. If the coffee then cools down, it's not that important. I've seen plenty of people insisting that the coffee has to be boiling hot, my stepmom's sister is one of those people. Then she waits for the drink to cool down, what's the point? Even people who can honestly say that they can drink anything above 165F without getting burned, which is rare for humans (not claiming non-existant, just rare), there is plenty of evidence that one can't really taste much at that temperature, all the nuances and subtle flavors go unregistered when that hot. One needs to wait for it to cool down, one might as well serve it in a cooler cup and enjoy it pronto. I believe part of the confusion comes from the fact that when one gets coffee in commercial establishments, the cups have been disinfected at very high temperatures and since they don't usually wait for the cups to cool down, people have the mistaken impression that coffee needs to be always served at high temperature.
And we've all seen the ugly fights between people who think coffee *needs* to be acidic and full of fruity and flowery flavors and people who think coffee needs to be non-acidic and have a clean flavor that tastes of coffee and nothing else. Just pick the stuff you like and enjoy it. The other folks are not bad or stupid, they just prefer something different from what the other camp likes. Think of it like this: you like your salads one way, someone else likes their salads with different ingredients and/or dressings -- neither person is bad, stupid or unrefined, they just like different stuff, and they should be free to enjoy the food they want without being called morons. That's just my opinion and if someone has a different opinion, I'm completely OK with that too as long as I'm not forced to agree with them.
