Double and single don't really refer to any specific volume of grounds.
Single baskets, have a smaller area on the bottom that allows the same
pressure to build through a thinner puck. Doubles and singles come in a
variety of sizes. For example, you can get Faema single baskets that
are sold as 6 & 7 gram 'volumes' and doubles that are sold as 12 & 14
gram baskets. All of these hold significantly more than the advertised
amounts when used with one of the Isomac machines.
The doubles generally hold approximately 16 & 18 grams, depending on
the coffee and roast. I rarely use the singles and don't remember
exactly how much they hold but I think it's 8-9 & 9-10 grams, which is
at least, if not more than, half of the double.
I don't own a triple basket but they seem to simply be a deeper double.
