I mentioned having done some early business with a certain store in Beverly Hills, back in the early days when, with the help of a couple of famous comics in town, they had "salted the mine" with wines acquired at auction (an Imperial I think, of 1929 Mouton-Rothschild was prominently displayed, but there were some "affordable" things as well).

But as time went on the logistics of the store faltered, and I was billed for a bunch of things I'd never received and that they'd run out of. So I stopped dealing with them.

When I mentioned this to the surgeon, he said "D___?! D___ is a crook!

Recently I read the amusing book The Billionaire's Vinegar, and D___ is in there, having been found out (and denying everything) selling a case of DRC Montrachet to a wealthy collector, which was proven to be counterfeit.

Apparently counterfeit rare wine is far more prevalent than I might have supposed. I am pleased to have drunk a lot of famous wines before they became so valuable that they tempted crooks to simulate, as I am reasonably sure the ones I've had were genuine.

I'd forgotten all about that. I knew it was something peculiar, as Google didn't jump the gun and display results until I asked it to.

Well, I guess she's safe from being counterfeited herself. "Accept no substitutes" the ads used to say.

I believe gasoline is still cheaper.. What's the difference: one liquid poison, another liquid poison... Gasoline is even more effective.

Nick Rivers is handed a bottle by Chocolate Mousse in the movie Top Secret!, and drinks and gags and spits it out. CM reveals it to be gasoline, of which he drinks heartily.

This would be the appropriate place to make some joke about Two-Buck Chuck being soon cheaper than petrol, at the rate things are going.

Of course, the IM products that are generated by the same non-linearity make detection even more apparent, as they will not be related to standard musical notes as well.
Spot on John as you can see I agree. Measurements are a good place to start then we listen.

It's gotten much worse in recent years with new collectors' markets and high demand in Asia. One recent auction involved wines which came from a guy who had already been busted for counterfeit wines, but (in collusion with the auction house) had the wines consigned to them from a third party.

There's a lot of fraud on the production end as well. And the writers who are supposedly neutral and objective, have huge ethical issues.

Anyway, this is far too OT. Let me know if you come through Austin and I'll pop a few interesting things of impeccable provenance.

Hello John

At what power do you achieve 7th Harmonic to -110dB.

Regarding that 7th, the problem here is that numerous empty statements are quite contrary to the real results.

Similar with power supply harmonics rejection.

Earl Geddes never answered me when I inquired about this, he presented some example spectra but one had bad mains sidebands and I don't know of any instrument that includes them as THD.

bcarso - Anthony's Pier 4 (of all places) had DRC Montrachet on the wine list at $60 in 1977.
