Dryness is a property of alcoholic beverages that describes the lack of a sweet taste. This may be due to a lack of sugars, the presence of some other taste that masks sweetness, or an underabundance of simple carbohydrates that can be converted to sugar by enzymes in the mouth (amylase in particular). The term "dry" may be applied to types of beer, wine, distilled spirits, or any other form of alcoholic beverage.

http://pt.wikipedia.org/wiki/Vinho_seco

Vinho seco é uma classificação de vinho aplicado às bebidas que possuem até 5 gramas de açúcar por litro. Um vinho seco pode ser tanto tinto, quanto branco.

O vinho seco é apreciado por consumir praticamente todo o açúcar da uva durante o processo da fermentação. Isso mantem as caracteriscas do vinho e da uva utilizada na produção.

Estou referindo das bebidas secas (espirituosas), conhecidas, na Cidade da Beira, vulgarmente por “tchacutchena”, são de marcas variadas, mas todas compartilham algumas características em comum: o tamanho do recipiente e o preço.

While i dont get my red wine, TASMAC sells cheap adulterated hard liquor at cheaper prices in a smelly dirty counter with a dirtier bar next door. It is indeed a deterant for the social/health wine drinker. However it opens the door for the alcoholic. When something is made so ugly it attracts and creates riff raff.
