When making flavored olive oil with dried herbs and spices, do I need to seal the bottles with wax or some other kind of sealing method?
Sealing the bottle is not necessary as a health precaution but might help keep the oil in the bottle. If a bottle of oil with a cork is accidentally put in the sun or heated, expansion can force the cork out, creating an oily mess. Shrink wraps and wax seals can help keep the cork in and add a decorative finish to the bottle. Screw caps are considered less likely to leak but do not look as upscale.
