Estate Papaiouannou founded by Thanasis Papaioannou, is one of the first producers who understood and promoted the idea that wine must maintain its unique characteristics. Mr. Papaioannou's son, George, a chemist - oenologist, continues the tradition and is as creatively active in his own vineyards as in the modern winery of Ancient Nemea, in the Peloponese region in southern Greece. The family has private owned vineyards in various locations of Nemea and the chosen grape varieties are cultivated with the aim of achieving ultimate harmony with the ecosystem. Papaioannou winery has been organically farming since 2004 and has been certified by the state controlled DIO and more recently has received USDA NOP organic certification.
