When wort is too cold, you get long lag times and increase opportunities for bacterial infection. When it’s too hot, off-flavors can form. Blichmann Engineering’s patented ThruMometer™ helps you get it right every time—letting you adjust wort and water flow rates in your counterflow heat exchanger to dial in an exact temperature with no more guesswork. Plus, you’ll use only the water you need, making this product good for the environment and your wallet. Available to fit 3/8” and 1/2” ID hoses.
