Well, I didn’t say that. Longtime readers may know that I am generally not a drinker of green teas, and especially Japanese greens, which tend to make me dizzy or feeling uncomfortable. The idea that shincha shouldn’t be drunk, though, isn’t coming from me. It’s from a man called Kaibara Ekken, an authority on Japanese herbs who lived during the seventeenth and early eighteenth centuries. In his work YojokunÂ (Instructions on Nourishing Life) he said a few things about tea drinking (translation mine).
There are many people now who drink a lot of tea from dawn to dusk…drinking a little tea after a meal helps digestion and quenches thirst. Salt must not be added as it’s bad for the kidney. One must not drink tea with an empty stomach as it damages the spleen and the stomach. One must not drink too much ofÂ koicha, as it damages theÂ qi generation of a person… People with weak constitution must not drink that year’sÂ shincha at all. It will cause eye problems, anemia, and diarrhea. You should only drinkÂ shincha after the first month. For people with good constitution, drinking it after the ninth or tenth month shouldÂ not be harmful.
In case the time here is confusing, the months referred to here are the lunar calendar dates. So for normal shincha harvesting would happen in the second month, which is around April. When he says one shouldn’t drink it until the first month, that means the lunar new year of the following year – that’s about a 10-11 months wait before drinking the tea. Ninth or tenth month would translate to about November or December.
The idea that green teas in general are cooling and isn’t a great thing to drink is not new, and many traditional Chinese medicine practitioners can tell you that excessive drinking of green tea is damaging to health. Kaibara is not alone in claiming this, but it’s interesting to see how emphatic he is with the idea that drinkingÂ shincha is pretty much a bad idea all around. Contrast that with the current obsession with drinkingÂ shincha as soon as possible, and the difference cannot be more obvious.
So by today’s standard, someone like him was probably drinking slightly stale green teas all the time. Interestingly enough, sencha, at least the ones I’ve had, actually do fine when aged a bit in an air tight container. I just had a little the other day – a can of a couple years old sencha that I opened but never finished. The tea brews a bright yellow, rather than the normal green, but it tasted very smooth and was actually quite decent. It also didn’t make me dizzy. I think these guys have a point.
