hi this is the first time that i have been on this site. i have a chance to get my hands on a starter that was origanily started in irland in the mid 1800's. my grand mother got a hold of it oh forty years ago or so and she just adds to it. my problem is that i don't want to take it until i can keep a starter. every time i make a starter and and i put some back to rebuild by the time i go to use it again it has gone bad. how do i keep this from happening? if anyone has an answer please help before i kill another starter.
