Storage of tea

[Guest guest]

Another question!

I keep seeing how you should never let kombucha come in contact with

metal. Is this really true? I also see things that indicate it's OK.

For example, Kombucha Wonder Drink comes in a glass bottle with a metal

cap. Also people sometimes cut their cultures with a stainless steel

knife.

I was planning to use ball jars with metal lids to store the tea. Is

this a bad idea? (Up til now, I have been re-using glass bottles and

corks, but I don't have many corks, plus this arrangement doesn't seem

very portable, if I want to bring the tea to work, for example.)

Thanks!
