The Secrets of Nespresso Pods

I don’t even drink coffee, and I am happily educating myself through this amazing video at 2:51 AM. As one does. 😂

More James this week?? Truly a Christmas miracle!

James, this is just a guess, but I think the jagged edges on the Nespresso receptacle may be flutes designed to allow a formerly pressurized vessel to be more easily extracted without tearing its rim off. When vessels get pressured, they're going to expand in volume a bit. That expansion can cause stickiness when trying to remove them from their chambers. By making the chamber fluted, you reduce the available surface area for that vessel to press into once it depressurizes (and thus reduces a bit in volume again), it becomes easier to extract. If you don't have that fluting, expanded vessels can stick in the chamber and then have a risk of their rims being torn off instead of properly extracted. Or it could be an anti-competitive thing, or perhaps both together at the same time.

The other side of the spectrum was my grandfather, whom I never met, and the story my father, used to tell with nostalgia in his heart from the days growing up in the 1920s. They lived in Juiz de Fora, Minas Gerais state, very close to one of Brazil's major coffee plantation regions in the 19th century, quite near the division with Rio state. My grandfather, who was a doctor and a carpenter, woke up earlier than anyone in the house, and he made coffee like this: First of all, he purchased very good quality beans from local small producers, and roasted them in the morning every day, with a cast iron cylindrical tool, by pulling previous night embers from the wood fired oven, fanning them with a bellows blower, roasting the beans just as he liked them, and proceeding to grind the piping hot beans with a French grinder I still have to this day. As soon as the grinding was right he poured them still hot in a pot of simmering water with a tiny, almost homeopathic dose of sugar cane water (sugar cane water has sugar and salt as well), and he had an interesting technique for brewing, by letting it just begin to boil, and removing the pot from the heat while stirring, doing this 2 or 3 times, and then straining with a cloth strainer (preheated and prewashed with coconut soap). My father described the smell of coffee spreading throughout the entire house, which made everyone rise from bed like zombies, and migrate to the kitchen where he had warm bread with butter, and this amazing coffee, most people had with a bit of milk, and my dad described as the most delicious brewed coffee he ever tasted in his life.

15:27 I never would have thought that I'd live to see James Hoffman using a scoop without a coffee scale to brew coffee. It truly is a Christmas miracle.

Am I the only one who had a Technology Connections moment when he pulled out the disassembled Nespresso machine? I was a little disappointed when he didn't say something like "Though the magic of buying two of them, I have an already disassembled one right here"

James, you are the gold standard when it comes to explainers on YouTube - enthusiastic, eloquent, expertise!

Ahhh, particle size analyzer is gonna give us some really nice, nerdy, weird coffee science content as I can see

"We now have a fancy particle size analyzer in the studio..." Of course you do 🤣😂🤣 Great video - thanks!
