Collect only large, dense acorns, passing up those that have obvious weevil holes or that are unusually light. Immediately when you get home, dump them into a large bucket of water—discard (compost or burn in your fireplace) the ones that float, keeping the ones that sink. For maximum yield, you can put them all in the freezer—this will kill any remaining weevils.
