What's in Your Cup of Coffee?

YouTue / Wired

Have you ever wondered what gives coffee its distinctive odor? How about those chemicals in coffee that aren't caffeine -- what are they, and what do they do? In this super-short video from Wired, we get a breakdown of what's in a typical cup of coffee...and why good things sometimes come in small doses.

If you like your data in old-fashioned "written" form, check out this Wired page, which conveys roughly the same info. For instance:

Putrescine
Ever wonder what makes spoiled meat so poisonous? Here you go. Ptomaines like putrescine are produced when E. coli bacteria in the meat break down amino acids. Naturally present in coffee beans, it smells, as you might guess from the name, like Satan's outhouse.

This Concrete Block Makes a Fine Espresso

Have you ever thought your kitchen could use more of a Soviet Union vibe? Do you find the fixtures in abandoned buildings charming? Then the AnZa espresso machine—essentially a coffee maker encased in a concrete block—may be for you.

According to Curbed, the AnZa is part of the art and installation aesthetic dubbed Brutalism, an architectural movement using spare, blocky designs. Moving away from the sleek, shiny appearance of most modern appliances, design firm Montaag crafted a rough block with simple knobs. As post-apocalyptic as it may look, it’s reputed to make a very good cup of espresso. And it’s “smart”: a smartphone app can adjust the brewing temperature to the user’s preference.

The project’s Kickstarter recently met its $145,000 goal and is now accepting preorders at Indiegogo for $799. You can hoist this subjectively beautiful appliance on your countertop beginning in March 2018.

Big Questions
What Is Pumpkin Spice?

Pumpkin Spice season seems to come earlier every year, but today marks its official arrival, as October 1 is National Pumpkin Spice Day. Before you reach for a cup, drink this in: The flavor can be composed of more than 300 elements—and pumpkin isn’t one of them.

Most recipes include cinnamon, nutmeg, allspice, ginger, and vanilla, but not every incarnation of the concoction is the same, according to a video by food scientist and spokesperson for The Institute of Food Technologists, Kantha Shelke, Ph.D, C.F.S.

So what’s the connection to the season’s most beloved orange fruit? (Yes, pumpkin is a fruit!) Flavor companies also add in skillfully designed compounds that mimic the taste of pumpkin pie. Each chemical is carefully reviewed by the U.S. Food and Drug Administration and approved at concentrations of about 20 to 50 times the normal consumption level. And even though the full flavor contains 340 compounds, combining only five to 10 percent of those molecules in a mix is enough to trick our brains into thinking, “Mmm, just like Thanksgiving!”

But beware: attempting to recreate the magic in the average kitchen isn't as easy as pie. With only the spices available at a supermarket, the final product will likely taste more like Chai than the seasonal treat on professional menus. “Pumpkin Spice isn’t set in stone,” Shelke says. “Everyone has their secret recipe.”
