If you store bottles in a milk crate raising the front up about 1" will prevent the bottles from sliding off. By raising it like that will still keep the cork wet. Reason you want the cork wet is to keep it from drying out. If you use synthetic corks then store them upright.Don't understand, don't we want to keep the liguid toward the corks. So do we want to raise the front of the crate or the rear?
