I remember the old flame war about that one. Many people insisted it was impossible but I seem to remember Ross getting an award for a Bohemian Pilsener fermented at 19 degrees.
Excellent condition, concealed element, bought from Craftbrewer and only done 3 or so brews with it.
Priced to sell at $200 (plus a couple bottles of your brew).
Recently bought a Braumeister so the urn needs to go to free up some space.
Located Brisbane Northside.
