MacPhisto the name of the roaster is 19grams but each container is 50g. The way I used it is two singles morning and evening @ 7.7g and two doubles @ 17.3g.
Funnily enough today’s Indian managed to get spot on. Single dose grinders make it so much easier especially if you’ve got some previous experience with same origins etc.
Vesuvius also helps a lot with its pressure profiles. I don’t remember when I last had a non drinkable shot.
