I was wondering how long the mixture will stay fresh. Will it spoil. I am planing on haveing a hive top feeder which will hold about a gallon. I was wondering if I couuld just make 5 gallons and be set for a while or will it spoil? Also I have seen several post/Youtube Vid on Bee Tea. Is that just kicked up 1:1 with some Tea bags and lemon juice added? will it make a difference?
