Store it like you would any living mix. like I like to do personally? i like to break it all up,put it all in a bin with a lid on it.NOT air tight.tight but take it off every few days to breath and mix it if it smells rancid,but once it starts to breath,it'll mellow some. but thats what I do. I did keep one in the bag for a little while now and it smelled mild actually. soo I think it was a mild batch potentially. kinda interesting actually since most smell really rich. but thats my guess man, and what I would do if your going to be storing it for a little bit. more than a cpl weeks imo.
