Pomace is the pulp that's left after the extra virgin and then the pure olive oil are pressed out. They use steam to extract whatever's left in the pomace and that's pomace oil. Think of the grape juice they press out of the grape pomace (and then ferment to make brandy or grappa) and you'll get the idea. If you go to an ethnic store with a serious selection of olive oil (20 or 30 types in gallons), you'll probably find a couple that are pomace oil. It's quite a bit less expensive than extra virgin or pure. I don't think they bother to package it in smaller ontainers. Rick
