Hi, I followed the advice from my previous post \[[Need help understanding V60 extraction with washed vs natural anaerobic](https://www.reddit.com/r/pourover/comments/1sc8s2n/need_help_understanding_v60_extraction_with)\] and decided that instead of grinding heavily processed coffee finer, like anaerobics, I would grind it coarser. I increased the grind size from 20 clicks to 25 on the Comandante C40. I also bought a new coffee, Electric Lime from DAK.

Yesterday I decided to use these new parameters:

Grind size: 25 clicks  
Water temperature: 88°C  
15g coffee / 250ml water, 45-second bloom, 3 pours

**Electric Lime - brew time: 2:40**  
My God, it was the best cup of coffee I have ever had in my life. Honestly, my local café could have served a cup like that. It had extremely high clarity, huge sweetness and complexity, and only minimal acidity. The flavor kept changing as I was drinking it, and the aftertaste was very pronounced. I could genuinely taste eucalyptus and floral notes in the coffee. It was perfect. The only thing I might complain about is that I would probably increase the dose to 17-18g, because the cup felt just a little too light for my taste.

**Fawaris AMA - brew time: 2:00**  
I had huge problems with this coffee before. It always came out as fermented acidity. But not this time. It was not as clear as Electric Lime, but you could still feel the weight of the fermented fruit notes. At the same time, the coffee was sweet and had a very distinct stone-fruit aftertaste. I was shocked that this coffee could taste this good.

In general, both coffees were 10/10. It felt like I had finally reached the holy grail of brewing: the perfect balance between sweetness and acidity, high extraction, and complexity. These were some of the best cups of coffee I have ever had in my life, even compared to coffee shops.

I should mention that I use the Beanconqueror app to log all my brews in order to improve consistency.

Today I decided to brew both coffees again, and what happened? Total garbage. Fawaris AMA came out acidic, with zero complexity. Electric Lime turned out much better, some sweetness was still there, but it became very one dimensional and completely lost its complexity. The individual tasting notes were no longer noticeable.

It genuinely made me depressed. I used the same grind size, the same water, and the same brewing method, and still it was disappointing.

I understand that with V60 it is hard to get perfect pouring consistency, but how is it possible to get a 10/10 cup one day, then something like a 6/10 the next day, and in the case of Fawaris AMA even a 3/10?

I’m attaching a video of my pour-over. I was a bit stressed while recording it, so it did not come out perfectly, there was some dripping. The coffee in the video is Electric Lime, and compared to what I got yesterday, it turned out average. Total brew time was 2:30, compared to 2:40 yesterday. I would really appreciate any feedback and advice.

  


Why Did My 10/10 V60 turn Into a 3/10 Cup Overnight?
