This wort chiller is designed for fast chilling of 5 to 20 gallons of wort. Constructed of 50' of 1/2" od copper tubing and brass garden hose fittings. Designed so that most of the coils rest near the top of the wort, the hottest area, to increase efficiency. Recommended for 10 to 15 gallon batches, but this chiller is really too big for a 5 gallon batch. PLEASE NOTE: This is a black and white photo. The wort chiller is made of copper, not stainless steel!
