\"\"<\/a>On Sunday, December 24, 2017, I brewed a Kolsch-style ale. After reading about the style, I put together a recipe. I made an attempt to reduce oxygen pick up in the mash tun by running the mash water into the mash tun through a silicone tube to bottom fill instead of running it in from the HLT spout. I also used the tube with a SS float ball on the end to run the sparge water into the MT versus my normal copper drip ring. Not sure how effective these oxygen-limiting practices will help since there are so many other opportunities for oxygen to enter the hot side system.<\/p>\n
