The time the pomace is in contact with the extraction liquid is of less importance. Countercurrent extraction is a more satisfactory washing system than simple multiple-contact since satisfactory sugar levels in both product and washed pomace are easily attainable with countercurrent washing. %U https://www.ajevonline.org/content/ajev/16/1/14.full.pdf
