Espresso

Why not? I argued music with musicology graduates too, and won ;¬).

Nah, I don't realy want to argue, just know how to prepare the coffee. Water just under the boiling point at high pressure simply is more then 100°C (of cource it cools down rather quickly after it comes out of the pressurised area), there's not much there to argue about.

S.I. is Systeme Internationale (international system), basically what you would call metrics, used by some countries, except that the man (and espeically woman) on the street will use Cal. instead of Joule for reasons I never understood and that HP still gets used instead of Watt for reasons I don't get either. Sientists regardless of country use it because sientists don't like arthmetic, at least not as much as many people believe they do, and there are way less constants and weird nonlinear factors when calculating based on the S.I.. It's generally a very good idea to use it, I think, unfortunately it was a mostly French idea so some of those English speaking countries don't like it. This means those contries are stuck with a system that counts partally in a system based on 12, partialy on decimal and they are stuck with foots and thumbs and stones and heaven knows what other medieval affairs. Probably still use a lunar callender too.

Most Americans would call this the metric system or the MKS system.

It is unfortunate that a new name based on French would have difficulty being accepted. At least the French can be proud of GSM. It's being used in the US by Cingular, which is not the biggest mobile telephone company, and they haven't changed the name. Shocked

Spank me? What for now? It's not my fault! I'm not the one who wants to have water that's not too hot yet is also remarkably hot for water in a liquid state at the same time!

That guy seems to attach a lot of value to having the water under enough pressure and aparently it's not for keeping it very hot so perhaps it's the power of the steam rushing out that's of importance to him?

Anyway, GSM is a better idea for mobile phones anyway, it' s a case like the 50Hz vs 60Hz powergrids. In both cases some issues were discovered after the system was implemented in the U.S. so when the Eurpeans thought it'd be nice to have one too they improved on the design.

Now we have all sorts of silly issues like video gaems that run slower in Europe die to the lower television framerate here.

I'm not sure there is anything to argue about. He says with the French press to use water that is below the boiling point - best if 190 - 200 F, the range used in espresso. There is no pressure with the French press device. He says it is not espresso, but a different beast. He does say it is the best method if you don't use espresso.

Apparently in espresso, the temperature is 190-200 F and it is under high pressure (15 bars) in the brewing chamber.

Illy is the coffee that Paul Vanuk served me at Different Skies. It was absolutely superb.

I suspect it's different. I suspect with esspresso the water will be that temperature once it's out of the coffee again or on average while it's inside of the coffee powder. If it's that temperature under high pressure in the boiling chamber then I don't think it'll come out as steam because by definition water only becomes steam above it's boiling point (even if that boiling point may float about depending on the pressure). The steam will cool down rather rapidly, more rapidly then water just below the boiling point, once exposed to air because shifting to gasseaus form will cost it energy as well as the fact that it will have a greater area of exposure to the outside air. I don't think it makes sense to have all that pressure if you don't intend to get it above it's normal boiling point.

I sugest we do research and have Cebec plot it all out on nice graphs. We can then send a bug report to MIT, South America or both.

Well, prey tell, what do you use now, and how does the coffee compare?

After doing more research, the units with the electric pumps use the pumps to pull water from the storage tank into the boiler chamber.

OK.. nothing like the Austin Powers stuff then
That would be swedish made I reckon.

The lavazza stuff is what I usually buy. Absolutely decent coffee.

What can a poor addict do when the good stuff is being kept off the streets?
A conspiracy I tell you.

Hey, look what just showed up at our local market in Allentown!

I agree, not bad. Milder than much of what we get in cans labeled espresso, but it has quite a buzz.
