Columbia is usually really good. I roasted one that had apple notes to it. It was amazing, and I’ve been searching for that flavor note combination since. Thanks for sharing the link!
It would be really cool if you could use a compressed air tank that you can recharge with a bike pump. Something like this has a max of 200psi and is refillable with a shrader valve. More upfront cost but but you don’t have to buy CO2 cartridges.
I think part of the appeal of the espresso maker this guy DIYed is that it has no pump/electrical components. Less points of failure and cheaper to make, cost seems to be a driving factor in his design. A bike pump is a fairly common thing for someone to own.
I steam milk for latte's quite a bit. Tip carafe so wand tip is at the side just under the surface of the milk, with the stem against the spout. Engage steam just enough to you hear a tearing sound. Gradually lower the carafe to maintain the tearing sound for 17 seconds,(the sound changes) then immerse the tip until the carafe is getting too hot to touch. Then a tap on the counter, and a couple swirls to break up bigger bubbles.
I would also like to add that the milk and foam separate very quickly. With my machine it starts even before the milk is fully ready, so i like to pour the steamed milk into another carafe and back then the taps to ensure it is properly mixed for best results.
Also just additional information: I know it’s not great but it’s at least a start! Due to girlfriends allergies, all I have to work with for the time being is oat milk (Chobani Extra Creamy). I’m thinking I could get better results with more practice, but I’m not sure if there’s only a degree of perfection I can reach using this milk alternative. I suppose time will tell
Yeah, caffeine blocks the adenosine receptors in your brain. Adenosine is a chemical your body produces throughout the day to signal you getting tired. That’s why when you drink coffee, a few hours later you might feel a “crash”, because all of the tiredness comes rushing back into your brain at once
Like the article suggests, that blocking of adenosine receptors happening too late can mess with your sleep quality, because your body wants to sleep, but your brain can’t because it doesn’t feel tired. So you might end up getting poorer sleep. This could lead to poorer long term memory storage/encoding, because one of the functions of sleep is to take short term memories and store it in your long term memory.
I drink a lot of coffee, but I usually stop around 4 or 5pm because even though I normally sleep well, I’ve definitely experienced caffeine-induced insomnia.
