Mathematicians are a step closer to understanding what makes a perfect cup of coffee.
Through some complex calculations, they have shone a light on the processes governing how coffee is extracted from grains in a filter machine.
This could help drinkers optimise their cuppa by applying a more precise - and scientific - approach.
The work is published in the SIAM Journal on Applied Mathematics.
When it comes to coffee grains, size matters.

If they ever find a way to make coffee taste the way it smells when brewing, I'm converted. Until then, I'll limit it to an accompaniment for chocolate foods.

How many times do I need to say this every time someone says coffee tastes bitter? It's bitter because the water was too hot, do not let it get to boiling temperature during brewing. Use a french press if you can't find a coffee maker that doesn't boil the water. Costco's Jose's Vanilla Bean is my favorite.

I find an Aeropress, not using over hot water, and only letting it steep for 30 seconds eliminates most of the bitterness.
If you really want coffee that's not bitter, try cold-brew, or Black Blood of the Earth. Cold brew is too powerful for me though.
