Mikey, Be certain to calibrate your thermometer. It is quite simple. Use a large glass such as a pint and fill with ice. Pour water on top of ice and then add more ice. Place the thermometer stem in the ice water and it should read 32 degrees F. If you can not move the pointer on the analog thermometer (normally located on the back of the face and is in the shape of a nut), fudge whatever degree(s) is necessary when taking a beer temperature based on what the thermometer was reading in the ice water. Easiest method for taking the temperature is to pour a beer and chug it and then pour another in the same glass and take your temperature. If your thermometer has not been used for other temp. issues such with body parts[xx(], drink the second beer!
