Is it alright to age a mead with a solid rubber stopper? I was thinking that if I was certain that the ferment was complete, I could perhaps just plug it with a solid stopper so that I do not have to worry about any contaminants getting in, or about keeping the airlock filled with water to the appropriate level.
Any concerns with this? Is there a reason an airlock is a better choice?
