In the quest of trying to understand how the different tastes of coffee come from different variables of the brewing process, I figured I would do a little experiment.
Does the taste (aroma, sweetness etc.) of the coffee change during the brewing process?
Quite simply, I made a standard Pour Over brew into five different cups.
30g of coffee for a total of 500 ml water.
The first cup received 60 ml for the bloom, then another 100 ml. I then moved the filter to the next cup, filtered 100 ml, and so on. The fifth cup godt the “leftover” 40 ml for a total of 500 ml for the entire brew:
Five cups, one brew
To my big surprise, there was zero difference in the aroma, bitterness and fruitiness of the coffee between all five cups! The only difference was the strength of the coffee:
The strength of the first cup was considerable, while the strength of the last cup was almost non-existent. However, the flavour profile and composition was identical between all cups.
TLDR: If you are in a hurry, you may choose to stop the brew when there is still water in the filter. You will get a stronger, slightly smaller cup, but the flavours are pretty much the same.
What do you guys think? Has anyone else tried something similar? I would love to hear about it!
