Seeing that mead is photo-sensitive the darker bottles are better, Just in case some light gets in. So my next problem will be oxidation. I am going to assume that a cork is more air tight than a screw on. I
Right now I am thinking amber bottles 12oz to 16oz possibly with a flip top to save time on the capping.
Choice of bottle and closure is a very individual choice and as you can see there are many options, so I recognize it is a bit challenging to get your arms around.
First of all, start with color of bottle. I mostly use clear bottles because I like to be able to see the beautiful clear mead. I don't keep the bottles sitting out in the light. If I did, I would use colored bottles, but I'd be partial to the Cobalt blue ones - they are really pretty to me. You may have other preferences.
Then for the closure. I think wine bottles and corks make the most elegant presentation. I like to put a nice label on as well. When serving it, presentation is half the battle. I have served the same mead, one in a pretty-label wine bottle and the other in unlabeled bottles - guess what? I keep getting compliments on how nice the mead in the wine bottle was, even though they tasted the same (to me). If you aim to impress anyone, wine bottles and corks fit the bill. Of course the choice between styles of wine bottle (Bordeaux, Burgundy, Hoch, or other) comes up - take your pick.
With that said, from a strict point of view of preserving mead and preventing oxidation, the two closures that provide the highest protection against oxygen are screw caps and crown caps. For long aging (4+ years), some recommend waxing the crown caps - I'm not yet certain if that is really needed, but it couldn't hurt.
High quality natural cork comes next, followed by Zorks, and then synthetic corks. Flip top bottles work well, but for long aging the rubber seals may dry and crack allowing air in.
So the next step is to decide you long do you plan on aging it. If the answer is "I plan to drink it so fast I won't be able to keep up with production" then you can use any alternative and the cheaper the better; so flip tops and crown caps become really good choices.
If the answer is "I want to save it for my daughter's wedding and she's a baby" then natural cork may be the best choice, or possibly screw caps (crown caps).
The fact of the matter is, that in the wine world, they still haven't determined if any choice other than cork is reliable for long aging of fine wines. There are studies being conducted and trials being run (both public and private) but the jury is still out. With mead it hasn't really been tested at all.
So there you have it. Clear as mud. ;D
