The Eva Solo tea maker provides two options for preparing tea depending weather you are brewing teas with or without tannin. The first option allows you to brew black teas or green, herbal and fruit teas where leaves are added directly to the glass for optimal brewing. The filter then strains the leaves when pouring. The second option for leaves with tannin places the leaves in the filter and once brewing is complete, the plunger is pressed down to stop the brewing process. Half batches can also be brewed as the filter extends to the bottom of the jug. The tea maker features a patented filter system, a drip-free pouring lip and an automatically opening flip-top lid.
