I have brewed for a little over 2 years now. I have brewed a BUNCH of beer and have never gotten " nervous" about anything. I am getting ready to make a starter and have done it a dozen times in the past. HOWEVER this time I am going to boil the starter IN MY FLASK ON MY STOVE. I don't know why but that is giving me the heebie jeebies for some reason. It may be that we had a glass corning ware pan explode on the stove once, but I am leery as heck about this.
