This is a 1 person homebrew site. I started in 2016 with a small batch 25 l equipment. For the Challenge, I will put my stuff to the newarby Danube river and brew outside in the green. I informed some interested people about the challenge, maybe I will have some helping hands over there. Position is 48°13'53.4"N 14°33'49.3"E ! Looking forward to hearing of your challenge results. Cheers, Lutz
