I drink a lot of tea, my tastes run the gamut - black, green, herbals, etc. I also drink a lot of pu'erh tea, but mostly from the traditional brick format or loose. I've been looking for single-serving size to drink here at work, and so I tried this. I haven't experienced any of the fishy flavor that others have reported. Granted, the quality isn't as high as the premium stuff I buy to drink at home, but this tea is a great buy. Good taste, packaged well, is definitely a pu'erh (fermented). I don't drink pu'erh for whatever weight-loss this is associated with (and I think it's a load of hooey - you lose weight by burning more calories than you consume, it's as simple as that), I drink it for the taste, and this brand fills the role perfectly.I've even used a few of these bags as part of my 'Americanized Tibetan Butter Tea' with satisfactory results. For this price point, I would easily recommend this tea for anyone looking for a good 'basic' pu'erh - though if you can find a chrysanthemum pu'erh for the same price point that has good reviews, go for it!
