On hot days I prepare a 1:8 ratio of ground beans to water and let it soak for 24 h at 4 C. It never felt different from regular hot drip coffee despite hearing that cold brew has a higher caffeine concentration. Guess I know why now - 150 mg in hot drip vs. 207 in cold brew is only a 38% increase in caffeine concentration.
Hmm, coldbrew over a scoop of good vanilla ice on a hot day. Fantasic
WTF is good vanilla ice? Is it as delicious as it sounds?!
Ice ice baby /j
Made from real vanilla, real sugar, eggs - italian gelato, for example.
Ooooh you meant ice cream. I thought you had like some kind of hack for making vanilla flavored ice cubes!
Hmm, now that you mention it. Maybe a simple syrup with some vanilla seeds mixed with water and frozen? I could see that work
Ooh, I haven’t tried that yet but it sounds tasty af. Good thing I’m about to make a fresh batch of cold brew!
See, if your favorite coffee place offers an Affogato it's fantastic
I’ll have to look the next time I swing by and I’ll report back. Thanks for sharing!
Depends on yur ratio of coffee to water, obviously.
I think they’re referring to the fact that cold brew is usually made in a concentrate. It’ll taste pretty rough at that high of a concentration, most people cut it with water or cream to make it a better flavor, but obviously that’s going to reduce the caffeine concentration too
Yeah. My heart rate and eye twitch is what caused the initial search, though. Whatever the levels are in this particular batch, a 32 oz tumbler was a poor vessel choice and chugging was a poor consumption rate decision.
Is this due to the duration? Like cold brewing coffee overnight in the fridge? What grind is recommended?
I actually work directly with food scientists. I'll ask somebody when I'm feeling more myself!
And yes! I learned how to do it yesterday. It's dummy simple. The most course grind possible is what appears to be recommended. You brew 1 part coffee to 4 parts water in the fridge for 12–18 hours. Then you just strain it. I do not recommend rapid consumption 💀
EDIT: Yeah, it's the duration. Hot brewed coffee has a not-insignificant amount of caffeine because a smaller grind puts more surface area in contact with water at any given time, and the hot water accelerates extraction of caffeine (and flavor) from the grounds. Cold brewed coffee blows that out of the water, even with a super coarse grind and even at super low temperatures, by virtue of the time involved.
