Tea Wing carries a select range of Japanese teas (the owner personally goes to source in Japan each harvest), and matcha is their signature product. I visited the Tea Wing headquarters for a taste, and their offerings were easily best matcha I've tasted in US.

In the fall, I trade in iced tea for warmer lattes, more specifically matcha lattes, a longtime obsession of mine. The best ones came from Tafu, where they topped each heady concoction with whipped cream and kuromitsu or even silky housemade chocolate syrup if desired. But with Tafu closed, I set out to find the best spots for matcha lattes in NYC.
The Winter Warmth ($4.50) at Soy Cafe couples frothed matcha with a spicy shot of ginger-infused honey. It's at once invigorating and comforting, and just sweet enough.
