Researchers have discovered that the static electricity generated during coffee grinding is influenced by the bean’s moisture content. Adding water before grinding reduces static and enhances espresso quality. These findings, offering economic benefits to the $343.2 billion coffee industry, also improve the consistency of espresso shots. Adding moisture to coffee beans before grinding reduces static electricity, enhancing espresso quality and offering significant benefits for the coffee industry. The fracturing and…

Grinding coffee beans with a spritz of water can reduce static electricity, creating less mess and improving the taste of espresso, according to Oregon-based researchers who borrowed from the physics of volcanoes to design the experiment. The team of chemists and volcanologists found that the inside of a coffee grinder creates similar conditions to those inside a volcanic eruption.Zillow Says You’ll Buy Your Next House With… AI? | AI UnlockedDo your coffee grinds ever fly into the air or stick to your grinder?

Portable monitors have, for the most part, stuck around at 1080p resolution. There aren’t any big ones either, with most topping out at 15 inches.

With all these special features, however, comes a massive price tag, as well as a bevy of accessories that you can, and in one case need, to buy.espresso 17 Pro: Price and availability(Image credit:…

If you purchase an independently reviewed product or service through a link on our website, Rolling Stone may receive an affiliate commission. We got by just fine for years with single-serve coffee machines from Keurig and Nespresso. But, after upgrading to a Breville Barista Express, we’ll never go back to single-serve.

Since then, I’ve gathered roughly 10 years of experience working in specialty coffee shops. Coffee is a personal and professional obsession of mine, and I’ve become truly fascinated with some of the technology in the marketplace today. Everything on this list I would use myself, and these gifts will absolutely improve the experience of any coffee lover you’re shopping for. Some pieces carry incredible…

Scientists found that more finely ground coffee beans result in weaker espresso due to uneven extraction. They used a simple mathematical model to split the coffee into two regions and examined how uneven flow affects the brewing process. This uneven flow persisted across different parts of the coffee bed, impacting the taste of the coffee. By understanding and preventing uneven extraction, it may be possible to improve coffee brewing and achieve financial savings through more efficient coffee usage.Understanding the…

Coffee Data ScienceAnother experiment to isolate headspaceHeadspace is the amount of room between the top of the coffee bed and the shower screen during an espresso shot. It is one of the variables of the puck that interact with grind size, dose, and tamp pressure. More specifically, headspace is the amount of room a puck has to expand during a shot, and this can impact how water and gas flow through coffee.The challenge in optimizing for headspace is that it is convoluted with grind, dose, and tamp. I have generally…
