'Wine fat' in the Bible

Wherefore art thou red in thine apparel, and thy garments like him that treadeth in the winefat?

From that time one hath come to a heap of twenty, And it hath been ten, He hath come unto the wine-fat to draw out fifty purahs, And it hath been twenty.

And he began to speak unto them by parables. A certain man planted a vineyard, and set an hedge about it, and digged a place for the winefat, and built a tower, and let it out to husbandmen, and went into a far country.
