Enjoying my second MengSong sheng in the past week. Smooth and mellow with a gentle fruity sweetness. I’m a fan. Although very enjoyable right now, for me I think this one will benefit from a few years of maturity to reach its true potential. Comparing the 2005 6FTM Mengsong 357g vs. the 2011 Dayi MengSong, I would say they definitely share similar characteristics (as one would expect with material from the same area). Similar in cost when price is calculated per gram so either tea would be a worthwhile purchase. My personal preference is the 2005 6FTM cake since I found a more complex flavor profile and more durability. So my plan is to drink the 2005 now and go back to the 2011 Dayi in two to three years when it should yield a very exciting cup.
