How many 12 oz cups of coffee can you get out of a airpot carafe?

a 2.2 liter airpot =75oz

so if you use the 1tbsp per 6oz (most Business not home ratio)

for med body- 2.2 liter airpot = 5oz coffee per brew

or go with old saying of 1oz coffee per 14-20oz water

if 2.5 liter airpot use little more or if want a "strong" cup of coffee keep going until you like the flavor, just be aware of the cost!
