O uso de cobre na confecção de destiladores e acessórios para a indústria de bebidas destiladas é uma necessidade para o ganho de qualidade sensorial da bebida. O presente trabalho teve por escopo correlacionar o teor de cobre com o grau alcoólico e a acidez do destilado. Constatou-se que os teores de cobre durante a destilação acompanham os teores de acidez do destilado, encontrando-se ambos em maior concentração na fração cauda. Cortando-se a destilação do produto com alto grau alcoólico os teores de acidez e de cobre são reduzidos. The copper use as a material for stills and auxiliary piping manufacturing is an important factor that affects the sensorial distilled beverage quality. The aim of this work was to study the relationships between copper content and alcoholic degree and the acidity levels in the distilled product. Copper levels during the distillation process follow the distilled product acidity levels, where greater concentration of both of them in the tail fraction was noticed. When the product destillation is stopped at a higher alcoholic degree, the acidity levels drop as well as the copper contents in sugar cane distilled beverage
