halfinch - 14 degrees should be OK although a little on the cool side. prolly better to have it sitting at around 18 for ales. make sure you take a hydro reading b4 bottling to ensure it is fermented out.
i wish i could have my fermenter at 14. just brewed a lawnmower ale with 85%pils. 10% flaked maize and 5% munich, using US-56 yeast. and saaz hops for a pseudo lager. Trying to crash cool atm in laundry trough with ice.
