I use wine bottles, but not for the green glass. I use Vacuvin stoppers and the pump they come with to pump out some of the air. The resulting partial vacuum makes a good seal. Developer is a reducing agent, and as PE has already said, you want to keep it away from oxygen in the air. This might be overkill, but the stoppers were cheap and have lasted for years.
Yep, and it is harder to make sure that it is clean of grunge next time you want to use the amber bottle.
Exactly...I keep my dektol in a clear glass jar and I can easily see if it's getting a bit too dark brown even for proof prints. If the bottle was brown, I wouldn't be able to tell.
I like the wire-bail beer bottles because one can't lose the lids, but it's difficult to pour back into them without a funnel, so I've been transitioning to wide-mouth salsa bottles for print chemistry.
Also I have never found a good 2L glass container, so I'm storing my D23 in PET cranberry juice bottles. No problem so far, but the inside of the plastic gets a strange dirt-like coating on it after a couple months. I never noticed this forming on glass bottles. You can wipe it off; it really looks like dirt and forms an even coating on the inside of the bottle. I threw out my last batch out of caution, but it happened with my current 3 month old batch too. The developer seems to work fine still but it's a bit puzzling.
