For afternoon tea parties paired with sweet and savory treats. Our Onyx Brick collection offers the most complex and unique selection of dark tea: Anhua Golden Flower Brick Teas. Not to be confused with black tea, dark brick tea is the historical forebearer of fermented tea. Dark brick teas undergo the most complex production process—yielding teas characterized by mellow taste and smoky pine flavor. As they age, the golden flower probiotics gradually flourish and the flavor slowly evolves.
