English to Portuguese Science Wine / Oenology / Viticulture Production of red wine

Já procurei o termo, e encontrei (um)a explicação do que é: Free-run juice is juice produced that flows freely from the skin of grapes before they are pressed. The natural weight of the grapes, when stacked on each other, tends to result in the release of some juice. Because it is not pressed with a presser, the juice contains much fewer tannins, and is thus less bitter. It’s sometimes called "the noble juice," and is more expensive because there is less of it, and it is considered higher in quality.

E também: After red wine is done fermenting, the solids need to be separated from the juice. In general, the “free run” wine is considered the best, highest-quality juice. “Free run” is what it sounds like—if you simply drained the juice off, or lifted out the solids like a tea bag, that’s the free-run stuff. http://www.winespectator.com/drvinny/show/id/46272

Mas não sei como se diz em Português europeu... Alguém tem uma sugestão? Obrigada!
