You just know how they found out about this...

Suuure...

Quoting more:

> "I got the idea of using espresso as a staining agent from the circular dried stains in used coffee cups," says Claudia Mayrhofer, who is responsible for ultramicrotomy at the institute. During preparation, she cuts tissue samples into wafer-thin slices and fixes them onto sample holders. Staining is the last step before examination under the electron microscope.

I'm curious about the grad student who is the second author on the research paper. Is he the one tasked with the current-SOP staining with (radioactive and poisonous) uranyl acetate? Was it his overworked-and-drowsy "oopsie" which lead to the discovery?

Make sure to leave out the hazelnut syrup.

Calling it now: this is ignobel prize-worthy research. If it doesn’t get a nod I’ll eat my hat.

Starbucks doesn't even have good coffee and it's WAY overpriced.

It's an abomination. Trust me!

Black coffee in McDonald's is superior in quality and price worldwide. Especially in UK and Switzerland.

Please explore - Starbucks is baaaad

Yes, their cappuccino milk is foamy, not creamy. For the price I expect cappuccino art. And they serve it too hot. 3 out of 5 stars at most and subtract one star for the price.

True but on the other hand their coffee beans bags they sell in stores made for the best coffee I have had.

I tried to buy beans from coffee snobs independant stores but all I got was weird and/or acidic coffee

But hey I am a tea person first and foremost, what do I know

I’m going to hate myself for saying this and sounding like such a coffee snob, but: if coffee tastes bad to you, there’s a decent chance you just haven’t had a good cup of coffee.

I only say this because I used to hate coffee too, only having had Starbucks or crappy supermarket coffee made at home. But then I had a cup of coffee at a very good restaurant and it was so delicious. It was just black coffee, good beans prepared right.

Turns out I just prefer light to medium roasts and found the right brewing times and temps that I like best. Every time I have Starbucks it still tastes awful.

There are actually a whole bunch of good medium to dark roasts out there, but third wave coffee is hip and has been for a while.

If you like Starbucks beans, you'd probably like a better dark roast. Try Lavazza. Coffee snobs will look down on it, but they're highly consistent like Starbucks while offering more variety and more flavor. Lavazza Super Crema makes a pretty nice espresso and is cheap relative to high-end coffees.

No... maybe you misread... they said coffee.
