I found myself very conservative in certain aspects. In the past I didn't want to even try cold brewing, because I always thought, what a waste of tea!
But then I got this si ji chun oolong that I really dislike
It has large, older leaves and becomes bitter after 1-2 infusions. I could smell some fragrance from the gaiwan lid, but in mouth, everything is shaded by bitterness.
I didn't know what to do with it until I realized this would be the good subject for trying out cold brewing
So I finally stepped out of my frame and cold brewed it, and it turned out great! The bitter flavor wouldn't be dissolved in cold water at all! Now this tea becomes a good office tea
I still wouldn't cold brew any of my favorite oolongs that turn out good in hot water (still think cold brew is somewhat wasteful). But the take home message is, if you don't like a oolong, try cold brewing before throwing it away
