Here is another test update. Water temp in the kettle 170 deg. Removed kettle from stove dropped in 5 32 oz bottles full of water with flip tops . After 5 min 138 deg . After 8 min 145 deg. After 10 min 149 deg. (Water temps in bottle). Conclusion: if 140 deg. For 1 min kills all yeast, your water bath need not be at 190. 170 deg water bath is safer, and could possibly be lowered another 5 deg. I just might try that tonight
