In many of the NB videos, they state that brown glass is best. Is this due to UV influence?
I have a number of swing cap bottles, but they are clear. They are also much larger than your standard 12 oz. bottle. I have been thinking it would be nice to make use of them, but I don't want to somehow ruin the beer. If it's just a UV thing, which I suspect it is, it's not being shipped and moved about, therefore not as much exposure to the elements. If it goes from fermenter, to closet, to fridge, to belly... not much exposure.
I would think that once it's been opened, I would be racing the clock for how long it would stay good.
Also with the swing tops, if the rubber is soft and squishy, it is safe. Originally it had a carbonated drink in it, so I am assuming that it would hold the carbonation of the beer. I guess I am asking, how reusable are the swing tops?
