For those interested in this sort of thing, James Hoffmann[0] has some really well presented videos about coffee, the making and iterating on, from the perspective of someone who's been working with and around coffee for a while (he was a world barista champion in 2007[1])

He's recently been making a series called Weird Coffee Science[2], where he looks at and tests scientific papers and weird ideas floating around.

Comments like yours are why Hacker News is such an important part of my daily reading. I did read your comment and then immediately thought: where else could I get such an interesting suggestion on a "generic" / "casual" topic like this?

Thanks for the links. I am an avid coffee drinker and I will check these out.

On Reddit? The coffee subreddit is pretty active, James Hoffman is also active there.

Beat me to it!

After watching that video I started microwaving my beans. It made such a huge improvement in the quality of my pour-overs that I've never stopped.

For the extremely coffee curious: I typically brew a V60, 25g coffee, 1:16 ratio, beans microwaved 45 seconds on high (950W rated output microwave). Baratza Virtuoso grinder.

Not to nitpick - but none of that info has as big an influence on the taste of your coffee as the one crucial bit you left out: What's the coarseness setting of your Baratza?

(For comparison purposes, I usually use 30g coffee, 1:17, grinder at 19, V60, 205F water. Most of these I can fiddle quite a bit with before you really notice, but the grinder setting really matters)

Wait a second, I thought the paper’s conclusion was the beans should be cool not warm?

In the industry, this paper has long been known as 'the grinder paper'. Matt Perger (one of the authors, and a World Brewers Cup champion) provides a good layman's explanation: https://www.baristahustle.com/blog/the-grinder-paper-explain...

Nice. Are you in the industry, by any chance, or do you simply know about it?

Curious to see if you have other unknown things to share for a layman like me.
