Numi's Aged Pu∙erh Tea Brick is a compressed bar of loose pu∙erh tea leaves. Unlike traditional teas that are oxidized for 8 hours, Pu∙erh undergoes a unique 60-day fermentation process resulting in a bold, earthy flavor with hints of malt. Pu∙erh is compressed into bricks and aged, like fine wine, for months, years or even decades. This increases its value and rich taste. Steeps 48 pots of tea.
