I am getting back into brewing after a several year lay off. I created a Jamil-type whirlpool mod to my pump/CFC setup and, to further tweak that, I sweated a small copper "T" shaped pipe that threads inside my brew kettle valve and hugs the inside lower walls in order to maximize post-boil run off and leave trub behind. After I sweated this small copper contraption with flux and silver lead-free solder, I heated all the piping, rinsed and cleaned off any remaining flux/carbon, and immersed it in StarSan for a while. By that point it looked completely oxidized (not shiny anymore). So, I went ahead and used it in brew session this past weekend. All went very well (seems like I haven't lost the touch :rockin
with only one concern: the exposed solder on the copper pipe (I am not an expert at this so not all of the solder I laid sucked into the joint - some of it is exposed) turned color from shiny silver to to a somewhat shiny goldish-greenish color. Is this something I need to be concerned about in terms of chemicals/metals in the beer? I know beer has a low PH so leaching somethng bad is a concern. The yeast are unaffected, happily fermenting away as I type - my main concern is will I be drinking something I should not be...
