ABSTRACT:
Alcoholic extracts of particulate solids for food or drink, and particularly of coffee grounds, are prepared in a squeezable plastics container which has a fabric filter disc across its outlet to trap the soaked grounds when the liquor extract is dispensed. A pull-off seal or cap is provided to close the container until needed. In use, liquid can be sucked back into the container by squeezing and releasing it, and used to wash a further extract from the solids.
