Agh, just the best flippen cupping bowls ever.
These tumblers weren't made for cupping coffee but they couldn't have been made any better if they were. Rounded bottoms allow for water to roll and submerge your dose while the handy 220ml size perfectly accommodates 12g of coffee and 200g of water for an ideal 60g/litre brew ratio.
These glasses ship in 6's. Can be used for regular drinking too.
