inspired Domatiotis to make a change. Chal-
lenged by the various steps of testing, he
managed to complete the design after “lots of
experiments with different materials as well
as to see how they react to the coffee”.
The most important two features of GEM
help users at all levels to reach a good cup: The
lid with a hole and the two different sets of
ribs. “With the lid, a close thermo system is
created,” explained Domatiotis. “The steam
produced is trapped resulting in higher kinesis
heat by four degrees.” The hole helps people
to pour towards the center as the water doesn’t
hit the walls but the coffee grounds, which
draws out coffee oils — “give you brew texture
and silkiness”. He said: “As a result, we could
maintain the right amount of strength and a
very significant sweetness with maximum in-
tensity and no need for circular moments.”
The ribs in the other hand secure a slow
flow rate of water to achieve a characteristic
flavors in a smooth way while ‘guiding’ the
water to exist faster as it goes down, “prevent-
ing over-extraction that will end up in bitter
flavors,” Domatiotis explained.

Plus, the material of the matching server in tough

To Domatiotis, the most important thing
during the design is “the taste of the final
brew”. “As a result, you need to focus on a
