Tons de Duorum White 2020

Tons, which translates to mean "tones," de Duorum is inspired by the bright colors that result from the reflection of the sun on the Duoro River, which creates different tones in the vineyards.  This wine expresses the terroir of the Douro Region, the result of a unique interaction between nature and human effort. 

Wine Production

Upon arrival at the winery, the grapes are de-stemmed and gently crushed, followed by pre-fermentative maceration at low temperature for 12-24 hours. The grapes are then pressed and fermentation takes place at controlled temperature between 14ºC - 16ºC.

Tasting Notes

Tons de Duorum has a sunny lemon yellow color and an intense aroma dominated by tropical and citrus fruits. Additionally, the wine finishes with everlasting flavors of flowers, crystallized fruits, and strident minerality.

Food Pairing

Pair this wine with sushi, ceviche, shellfish, cioppino, and grilled poultry.
