OLIVEIRA (Duarte de). O DESENGACE e Suas Vantagens na Vinificação. Porto. 1911. - OLIVEIRA (Duarte de) O DESENGACE e Suas Vantagens na Vinificação . Porto: Officinas do 'Commercio do Porto', 1911. 90, [6] pp.: il.; 180 mm. The first edition, published as a pamphlet in the ”O Lavrador” collection, would be republished in 1925. This technical treatise discusses destemming, the operation of separating the stems (the rachis from the bunch) before fermentation, a practice that was then not widespread in Portuguese winemaking. It discusses its oenological advantages, namely the reduction of astringency and the improvement of must quality, fitting into the movement of technical renewal in national viticulture following the phylloxera crisis. ⚑ Auto-translated via Google Translate
