I've been experimenting a little lately, with adding a pinch of sheng to my pot of shu. Maybe around 4g shu to 1g sheng, give or take. Has anyone else tried this?
Of course the result varies a lot depending on the tea, and many of my teas I'd never really consider mixing with others.... But some of them do seem perfect for it.
For instance, this 2008 Nan Jian Tulin 803 shu -- it's a good cheap daily drinker, doesn't really have a strong flavor, and responds well to a pinch of sheng -- spices it up a bit. But I'm not sure, I haven't tried it with Menghai shu yet.
I first got the idea from the folks at my local tea shop (they're from HK). They are big into 90s shu (don't sell much else, actually). The only sheng they had for a while was a very "tippy" late 90s maocha that was heavy on the barnyard taste. But they recommended putting a pinch of that into some of the stronger 90s shus to balance it out.
It definitely adds a dimension to the daily grind of tea-drinking!

Anyone else try it?
