Retsina's pine-resin flavor started as an accident — ancient Greeks sealed wine amphorae with pine resin to keep air out during transport, and the flavor it left behind became so beloved it was intentionally added ever after.
Retsina is white wine made mainly from the Savvatiano grape and infused with Aleppo pine resin during fermentation, giving it a distinctive piney, slightly resinous aroma alongside citrus and herb notes. It's served well-chilled, traditionally alongside meze.
