Pietra is a brand of beer from the Mediterranean island of Corsica.
Pietra beer is a 6% ABV amber beer, brewed from a mix of malt and chestnut flour. Chestnuts have always been used in Corisca as a cereal, but it was necessary to carry out studies for many years to validate the qualities of chestnut flour. The high fermentability of chestnuts helps to maintain the beer's head and gives Pietra beer its golden colour.
The annual production of Pietra beer is over 25,000 hectolitres.
