Very interesting for industrial use, that’s for sure.

For domestic use, in the home of somebody whose coffee snobbery is dialled to 11, I need far more information.

What beans were they using, freshness, etc? (Edit: Campos coffee… not on my shopping list that’s for sure…)

How did they control for extraction method differences to maximise output quality for all brew methods? (Edit: TDS and EY)

Were the “regular” coffee drinkers regular consumers of espresso?

Most importantly, how long until Hoffman does a deep dive and much will it cost so I can allocate budget for yet another coffee making device?

I felt a great disturbance in Italy, as if millions of voices suddenly cried out in terror and were suddenly silenced.

Espresso does not have milk.

Macchiato, is an espresso based drink with milk.

Edit: it's bad form to change your message after-the-fact to remove the thing that was quoted.

Even if that quote was left in, "espresso drinkS" usually stands for drinks based on espresso, not espresso itself. You know, like cappucino or macchiato.

Correct. An espresso drink may have milk in it. An espresso does not.

Edited to remove because the paper clarifies that it’s black coffee. But missed the (edit- found the clarification). Was quoted whilst in the process of fixing!

There are much greater sins against Italian coffee than dropping a word that doesn't change the meaning. "Espresso drink" vs. "Espresso-based drink"? come on.

For those sensitive souls I'd think they'd be more worried about "Expresso","Frappacino", "Puppacino", Starbucks, and 20oz "venti" lattes.

A mocha is an espresso drink. A latte is an espresso drink. A cappuccino is an espresso drink. An espresso is an espresso drink. Some espresso drinks have milk in them and some don't. Anyone offended by the question, "did the espresso drinks have milk in them?" is just looking for something to be offended by, as seems to often be the case with people who fly off the handle over the topics of coffee, pasta, and pizza.

You're using the term in an unnecessarily specific way.

I’m from Melbourne, have a Brewtus IV + Mazza Mini, probably have a low user ID on coffeesnobs, hung out every day our Prouds and Patricia’s, and can tell from first sip if the beans are South American, African, or from Sumatra, so you can probably tell I’m anal about my coffee… and all I can say is don’t knock Campos (especially their King Street).

It has probably been 10-15 years since I've had anything from Campos. Wasn't a fan. Will give it another shot if I get caught in Sydney again.
