Foil capsules were originally conceived to protect wines in damp cellars full of critters like boll weevils that feed on cork. However, given today’s modern storage conditions, those are likely no longer a threat. The closures we use to seal our wines are also not an attractive food source for critters. The truth is, capsules today are merely decorative and nothing more than an added expense. In the interests of keeping your costs low (and the fact that 99% of capsules are non-recyclable) we've decided to leave them off.
