Updates From the Boundaries of Espresso, Feb. seventh 2026
After our first spherical of testing on this topic, trying into the deserves or potential pitfalls of premade espresso + milk, we bought chatting with Dr Anja Rahn and Prof Steven Abbott. Anja was intrigued that we most popular the premade espresso + milk and theorised that the crema, or absence of it, have to be altering the tactic of supply of sure fragrant compounds to the palate. She prompt we attempt foaming up the chilly premade espresso to see if, as soon as it’s bought ‘synthetic crema’ on it, the resultant lattes can have a equally acrid style to the lattes made with contemporary espresso. So we did simply that, and on this new put up we’re letting you all know what we discovered.
From a sensory perspective, issues weren’t tremendously stunning — issues adopted the development we’d seen partially 1, the place the abnormal premade (with no crema) + milk was most popular in 9 out of 10 trials. What was fairly much more stunning was the way in which the substitute crema behaved: huge time Ostwald Ripening, which is a very intriguing to observe phenomenon of larger bubbles getting inflated by neighbouring smaller bubbles. Nice to observe, however horrible for texture… Other than that, it offered some good proof for Prof Abbott to succeed in a brand new idea about the kind of foam actual crema truly is: A Pickering Foam. Wanna know what a pickering foam is and why that may clarify why actual crema may be very persistent, synthetic crema ripens actually rapidly, and why crema tastes barely acrid? In response to Prof Abbott, “It’s the place small hydrophobic particles cowl the bubbles, making them comparatively resistant to bubble forces, and in addition ending up in your latte as little pockets of hydrophobic nastiness which is what I feel is happening along with your style buds.”
You’ll be able to form of see this within the pic under. Head right here and get the total story.

However you may discover this interview a bit diverting, as a result of it’s with the man who invented the kind of merchandising machine that had precise espresso grinds and contemporary milk inside it, versus on the spot espresso and UHT.

This one is hilarious: ‘87% of Individuals are keen to pay extra for a product/service if the customer support feels private (vs. transactional); Canadians are much less keen (72%).’ Come on, Canada!

Right here’s a quote that’ll get you considering. It’s from an article by Sarah Charles in regards to the ethics of specialty espresso. “In an trade that markets itself as each luxurious and ethical, the success of the producer can really feel awkward — even threatening”. Or this: “This mixture of excessive worth and superiority – ethical or different – is widespread in luxurious sectors: uncommon Hermès luggage, limited-edition Rolexes, and Frank Gehry furnishings all sign exclusivity. However these markets don’t embed specific claims of social uplift into their advertising. Specialty espresso does.”
