I have not brewed in the pot yet, but have been looking for where to do the brew. My big scheme (which didn't work) was to brew on the stove top. We have a big gas range and it has enough power to boil 5 gal, but there is a warning shelf on that stick out far enough and the pot is tall enough that they collide if I try to put the pot on the stove. Besides, my first receipt has about 12 lb of grain which I'm guessing will double in weight when it gets wet and I would like to have something above the rig to rig a pulley to to help with lifting the bag out of the liquid.
Oh, you asked what fittings I added. I have only added a 3 piece ball valve in one of the couplings and a plug in the other. I figure that I can use either my tea thermometer or the floating dairy thermometer to get the water to strike temperature and that way, when I get either my electronic thermometer or a bimetal one where the plug is now that I will really appreciate it.
One thing that is holding me up is that I only own one better bottle and it has an extract beer in it right now that isn't ready to bottle.
