We have our own little summer project, Coolship Brewing Company.
We are brewing in a hollow oak tree where the water is heated with hot stones. We only brew Raw Ales which is not boiled but mashed in, lautered and cooled down natural and then fermented.
We brew at the Viking museum at Ladby, Kerteminde, DK and it free to come and join us.
