Kölsch

For this batch I went with a nice and easy Kölsch.  It’s been almost two years since I brewed one and it’s the perfect timing with the summer approaching fast.  I will let it ferment for a month and then condition it in keg for another month before tapping it.  The odd hops bill is because I had some remaining Tradition and Tettnanger bags that I wanted to use up.
