I just deleted my comment wondering the same thing. I don't understand why something like opencollective couldn't be used. Give money to org, see how money is spent. The NFT is completely unnecessary.
The instructions I follow for my pourover requires 350 grams of water. Much more than 8oz. It drives me crazy, but it also tastes good! Though If I only poured until reaching the 8oz mark it's also quite nice. That said, there is a question of "full-extraction".
