Portafilter baskets - how are they measured / sized
I'd like to try a slightly larger basket on Isomac Tea, and am wondering how the sizes are calculated. I have put my empty double basket on a scale, zeroed the scale, then filled with ground coffee to my normal level, and weighed it as 21g of coffee. How do I work out what the actual size of my basket is?
I'm guessing that would make it a double. Based on precision basket sizing, 21 grams sounds like an overdosed 20 gram basket. Kinda hard to determine what you mean by "normal level". A triple basket would be 22 grams.
Thanks. The basket came with the machine as the double basket, so 20g sounds right. My "normal level" is probably slightly overdosed. I'll look for a triple.
