English professional term

[Valeriy]

Hello! I am not aprofessional and searching an English professional equivalent to a Russianb term which may be roughly translated into Emglish as "materials in wine-making". In original language, however, this term mostly (but not exclusively) means non completely finished product, that is what may already be called "wine", but still requiring some finishing processing, treatment. This semi-product is frequently transported in bulk.
Is there any professional English term matching this description?
Thank you.
