The worst idea that actually worked

Hey,

Someone left a comment daring me to do the thing you're always told never to do. Just boil your coffee. Not brew it, boil it, like the water on a percolator that keeps cycling through the grounds. So I did.

It started as a percolator question. A lot of people don't like percolators because the coffee keeps re-brewing itself, and they assume that has to taste burnt and bitter. I care about one thing, does the cup taste good. So instead of arguing about it, I ran it. I brewed two batches of the same coffee at the same temperature, then put them on the stove and let them boil for ten minutes.

One batch was my usual 1 to 15 ratio, about 70 grams of coffee. The other was a weaker 1 to 20, roughly 50 grams. Then I let both of them cook.

And this is where it got interesting. That 1 to 15 reduced down like a sauce on the stove. Think about what happens when you simmer soup for a while. It gets concentrated, stronger, and if you go too far it becomes too much. That cup came out at a 2.5 TDS reading, which is strong as anything, and yeah, it was bitter. Not as bad as I expected, but bitter.

But the weaker 1 to 20 that I boiled? That was the best cup on the table. More approachable, no real bitterness, and the acidity actually came through. I did not see that coming.

Here's what it taught me. Boiling isn't magic and it isn't poison. It's just heat and time, the same two levers a percolator plays with. Start too strong and you'll cook it into something harsh. Start a little weaker and let the boil do the extracting, and you can land somewhere genuinely tasty. That's the whole game a percolator is running, and it made me respect the thing a lot more.

And it eased a worry I think a lot of us carry. We get scared of an automatic machine holding the pot warm on a hot plate, like it's slowly cooking the coffee bitter. But think about the extremes here. I hard-boiled this coffee for ten minutes, and even that took a weaker cup to land somewhere drinkable. A hot plate is nowhere near that. It's holding your coffee at a low, steady warm, not reducing it down on a rolling boil. If ten minutes of an actual boil did what it did, a hot plate is doing far less to your cup than we give it credit for. Don't be too afraid of it.

Do you need to boil your coffee? No. Please don't, honestly, unless you're using a percolator, in which case this is basically how it already works. If your pour over is treating you right, keep it. This was a curiosity, not a new routine.

But that's the fun of it. I'd have never tried this if a viewer hadn't pushed me. Watch the whole boil test here. Then tell me the weirdest brewing idea you've been too scared to try. Hit reply. I might just run it next.
