Great advice, but unfortunately I am from the "Hi Test" community of coffee drinkers - dark, bitter brew with a shot of real cream. For years I drank it cold-brewed to lower the acid, but unfortunately the steeping process makes it even higher in caffeine - hence not for my tremors. Anything else is so unsatisfying that it just pales...
So I have switched to Chinese Green Tea - much more robust tasting than the Japanese style but still pretty low in caffeine. It gives me that astringent taste on the tongue like a good dark coffee. Just ordered a pound of my favorite (2022 harvest is closing out and 2023 coming in. Turns out every variety tastes different each year and and from each tea master - so I have become quite "bougie" about my morning cuppa.
