Social/technical networking field trip 14:00 – approx. 19:00

Field trip: “From groundwater to beer” A bus will take us to Truelsbjerg Waterworks for a tour and we will after that go to a local micro-brewery for sampling and tasting. There will be a drop off in Aarhus Central station at approx. 18.00 and we will be back in Horsens at 19:00. The trip is included in the delegate fee. Students can attend if seats permit, as we have limited seats for the trip.
