Looking over the market stalls of Camden,Yumchaa sells it's large range of teas to the throngs of tourists and locals alike. I needed a low caffeine fix and so their Pai Mu Tan, a Chinese white tea was just the ticket. ‘It is a very delicate tea, as it is only picked and dried, which leaves it with nearly no tannin or caffeine.' With undertones of sweetness it was the perfect pick-me-up for an already tea-fuelled day. I recommend heading to one of their many cafes to sniff all the tea samples!
