What the the precise strain and maker of this "premium" yeast?
Anyways, many lager yeasts are to be fermented around 50* F, and 18* C = 64.4F, so you are 10+* too hot.
Lagers really really need to be fermented in a temp controlled fridge/freezer chamber for the best results.
Most ale yeasts thrive at 18*C so keep it in mind for next time!
