What do the biology/lab gurus think of this?
If I sterilize bottles in my oven and allow them to cool in the oven (oven closed), then cap them with caps that have been soaked in 1 step, would they maintain their sterility until I opened them again?
Alternatively, if I loosely covered the tops with foil and crimped it on removal from the oven to keep the bottle caps out of the mix would I get a more acceptable sterility percentage?
It seems a waste to fire up the oven for two bottles when I could do six and pull them off of the shelf as needed for starters.
This assumes that all of the equipment I use is sanitized and I work in a clean, but not sterile environment.
Up until now I have "Baked" the bottles needed and poured boiling wort into them when they cool to about 200 degrees f, then put foil over the tops.
Thanks for the info,
Barry
