I follow this guy’s. He’s pretty funny.

But if you ever needed a video to show you how inconsistent coffee can be this is it.

I particularly like the part when he pours ground coffee back into his niche 🤣

Got to admit I had to fast forward parts, but I don’t see how massive changes in the water you use is coffee’s fault?

Coffee is really predictably consistent, a human throwing it a curved ball is going to cause more inconsistency.

Whilst I say coffee is consistent, I mean that some of the things we measure are very consistent, some quite consistent, other factors have a wide deviation, but seemingly little effect on consistency, so it’s a case of focusing on the things that matter.

The order goes something like this (at dialled in grind):

Dose - you can make this exactly the same every time.

Shot/brew weight, small deviation but bigger than dose.

Extraction in terms of mechanical measurement is next.

Taste preference deviation is larger than extraction.

Total brew time.

Flow time.

Changing the coffee has the biggest influence on flavour.

Changing water for extremes, I don’t know why you would do this, but you can tweak to effect acidity.

I recall a paper a few years back that said high bicarbonate/alkalinity water enhanced crema (I guess CO2).

    So, I too am guilty of not watching with full focus. But I think the section between 14 and 18 minutes is all about how he couldn’t get consistent measurement profiles from the Decent in pairs of shots.

    The main theme is about the sensitivity to water (or water-bean interactions), but the section above is about variation (not in a useful way, but in a “variation is not zero” way when you measure a lot of variables).

      My post was more tongue in cheek, than serious

      I was talking about how his shots and results at the start were all over the place, just made me laugh a little in a world where we seem to obsess over ever little detail, I mean the guy is describing the mouth feel of water….🤣 And yes I’m aware that water does taste different. 😝

      Thanks @Cuprajake I enjoyed the video. I watched the whole thing but to be honest I’m not sure what the conclusion was other than:

      1. If you use a mineral supplement like 3rd wave, make sure you use distilled water
      2. Don’t use mineral rich water like Evian

      Did anyone else have any key takeaways?

        My main takeaway is how impressive it is that someone can talk in a non-native language about a specialist subject (coffee) in such detail.

        I’d struggle to order a beer in any language other than English and here’s this guy breaking down the impact of water hardness on coffee output…

        (very much adding to the impression that his command of English is very good indeed)

          the other vid i like is this april fools vid from brian quan

          another funny watch
