Pedra de Fogo Madeiran table wine is a red DOP Madeirenses
The wine is produced by Elsa Maria da Silva Ferreira as with many of the small volume producers the wine is made at Parque Agrícola do Caniçal a shared facility for wine production.
The Pedra de Fogo wine is made from Touriga Nacional and Cabernet Sauvignon grapes.
I have not noticed this wine on restaurant wine menus and is not widely available in retailers either.
Tasting notes on Mad about Madeira web site report a light wines with Toasted oak, cherries and roses.
