Gosh, I don't know anything about the gasket-ed beer bottles. Did you find an answer or solution? We had two extra large bags of citrus - mostly oranges, grapefruit and lemons - given to us over the holidays. We shared with 4 friends and family. Yesterday I made 8 jars of Orange Marmalade with some, and froze enough prepared fruit and peels to make another batch later. There are still quite a few navel oranges and some blood oranges in the fridge. I think we can finish those just eating them.
