Thermometers

What it does :

Measuring temperature is critical for proper starch conversion during mashing and steeping of grains on the hot side of brewing. In addition, knowing the temperature of your fermenting beer is critical for desired yeast activity on the cold side of brewing.

What it is:

A thermometer is an instrument used to measure the temperature of a substance.

How it works:

The two most common temperature scales for thermometers are Fahrenheit and Celsius. Kelvin is frequently used in scientific pursuits, but we know of no brewers who use it. Brewer-friendly thermometers have a clip to attach to the rim of a brew pot, and have sufficient precision to measure whether desired mashing temperatures have been achieved.

Preparation:

Thermometers may be used during both the hot side (e.g. wort preparation) and cold side (e.g. fermentation, bottling, and packaging). For hot side use, they should be cleaned as you would anything else for food preparation. For cold side use, they should be sanitized if checking the beer’s temperature directly. Better yet, fit your carboy or fermentation bucket with a temperature sensitive indicator strip so that direct contact with the fermenting beer is not required.
