Sencha has many health beneficial components and depending on the water temperature the amount of these components that gets extracted will differ. Brewing it at low temperature actually will deliver many of the great components.
Sencha's caffeine comes out more in higher temperature. In general temperature under 60C will hold in the caffeine and when it is cold brewed the caffeine is said to be much lower compared to hot sencha.
In lower temperature bitterness does not come out from the tea, but the umami component known as the theanine, a type of amino acid, will come out more. This will bring out the umami and the natural sweetness of the tea.
There are several types of catechin that is included in sencha. One of the catechin that is said to be good for the immunity is the epigallocatechin. This epigallocatechin is extracted the most when it is brewed in low temperature.
