As per the quotes emailed the chevrah by RDE, this was to defend his
shitah that tea qualifies as tavlin. Is a bay leaf tavlin, or only
powders? These are whole tea leaves, not grains. But in any case, if
RMF argues that the hastening of the process caused by the water's
heat doesn't qualify as bishul, the chalos sheim "tavlin" seams
tangential.

However, you can taste the difference between tea made with cold water
and tea made with hot. For that matter, WRT green tea, there is a
marked difference between tea made with boiling water and tea made
with 180deg F (which is yad soledes bo, but not boiling). One that
even non-addicts would notice. I'm not sure if the metzi'us is exactly
as RMF assumes, although I couldn't Google an exact description of the
chemistry.

My mnemonic for remembering the boiling point of water (in Fahrenheit,
in Celsius, it's the definition of 100deg C): Gematria "rebbe".
