We picked up two sets of these for cupping our roasts and they are a good solid set of bowls.
The colored interior to help reduce the impact of appearance on taste/aroma is appreciated and is something my wife is used to from her work in a commercial beverage producer's sensory lab.
We also like that the lids are silicone instead of ceramic since this makes cleanup, handling, and working through the samples pretty quick.
The only reason I take off a star is because we did not receive any care instructions with the bowls and putting the silicone lids in the dishwasher caused them to become blotchy looking. Luckily, we seemed to have received two sets of lids, so we will hand wash the ones we didn't make ugly already and use the discolored ones as coasters during cuppings.
Overall, it's a good set, and we will probably buy a few more boxes in the future as we upscale.
Good quality as always!
I like the size of the 4 cupping bowls and the darker interior. My bowls held about 235 ml of water, so I used 215 ml water and 13 grams coffee for a ratio of 16.5. Works fine, and they look good.
