I plan on using real wort starters for my next few brews. The wort will be 'harvested' from my FV just before I pitch. To store it I had this idea; I will reboil the wort for a couple of minutes and put it in a jar almost to the top. Then leave overnight to cool. The boiling wort will sanize the inside of the jar of course. As it cools the contracting wort will help seal the lid tightly. Once cool I will store the jar of starter in the fridge (putting it in the fridge further helps seal the lid tighter) -perhaps for weeks What do you guys think? Any flaws?
