więc ZDECYDOWANIE nie jest to sok jabłkowy
proponuję liquor w znaczeniu podanym tu (jak widać nawet autorowi strony się to nie podoba, ale dla porządku podaje):
http://winemaking.jackkeller.net/glossary.asp
Liquor:
While I don't particularly like this term, associating it as I do with Scotch and other distilled spirits, it does, in fact, also properly refer to >>>>>the unfermented or imcompletely fermented, sugar-bearing liquid<<<< from which wine is made. It is also the liquid portion of a must. When the alcohol in the liquor reaches 8 or 9%, it can more accurately be referred to as wine.

ewentualnie 'must blend'
must to moszcz (SJP moszcz : surowy sok wytłaczany z owoców lub warzyw, używany do produkcji soków pitnych, galaretek i win)

definicja 'must' tu:
http://winemaking.jackkeller.net/glossary.asp
Must:
The combination of basic ingredients, both solid and liquid, from which wine is made. The liquid content of must is called liquor or simply juice, while the solids, when pushed to the surface by rising carbon dioxide, is called the cap. When the alcohol content reaches 8 or 9%, the liquid component is more accurately referred to as wine.
