My pour over/drip coffee pot recommends that I measure 10-12g of coffee per person whilst my grinder has markings to indicate whether the ground amount is for 1 or 2 cups. I notice that darker roasts being slightly more oily seem to weigh more and therefore the volume is less compared to a lighter roast so the question is which method of measuring is correct?
I understand that taste is subjective and I have been using 11g so far but given the variability in weight and volume is there a correct method which perhaps can be adjusted for different roast types?
