Brewing is an art form that requires precision and attention to detail. One crucial aspect of the brewing process is measuring the specific gravity of the wort, which is the density of the liquid compared to water.
This can be measured using a floating device, but that requires a fair amount of liquid and is not easy to bring out in the field.
A refractometer is a tool that allows brewers to measure specific gravity accurately and quickly without the need for a hydrometer and the whole liquid column setup required. A simple drop from a sample taken in the field is enough to get a precise reading.
The refractometer works by measuring the amount of light that is refracted or bent as it passes through the liquid. The more sugar present in the liquid, the more the light will bend. By measuring the angle of refraction, the refractometer can calculate the specific gravity of the wort.

What to look for in a refractometer?
When looking for the best refractometer for brewing, there are a few critical things to consider. Firstly, the accuracy of the refractometer is essential.
A refractometer that provides inaccurate readings can lead to mistakes in the brewing process, resulting in subpar beer. Secondly, the build quality of the refractometer is crucial.
A sturdy and durable refractometer is essential, as it will be used frequently and needs to withstand the rigors of the entire brewing process, wether you bring it to the field to sample apple or grape juice or testing your fermentations daily.
Finally, the ease of use is another important factor. A refractometer that is straightforward to use will save time and reduce the risk of errors.
When choosing a refractometer for brewing, there are several features that should be considered to ensure that you get the best product for your needs. Here are some factors to keep in mind:
Accuracy is one of the most important factors to consider when choosing a refractometer. Look for a product that has a high level of accuracy, as this will ensure that your readings are as precise as possible. A good refractometer should have an accuracy of at least +/-0.2% Brix.
The range of the refractometer is also an important factor to consider. Look for a product that has a wide range, as this will allow you to measure a variety of different liquids. A good refractometer should have a range of at least 0-32% Brix.
The construction of the refractometer is also important. Look for a product that is made from high-quality materials, as this will ensure that it is durable and long-lasting. A good refractometer should be made from metal or high-quality plastic.
Most analog refractometers assume a certain temperature e.g. 20C as a starting point, but many come with a calibration screw to offset that set point.
Automatic temperature compensation is another important feature to look for in a refractometer. This feature will ensure that your readings are accurate, even if the temperature of the liquid changes. Look for a product that has automatic temperature compensation.
Easy to Use
Finally, look for a refractometer that is easy to use. The product should be easy to read and should come with clear instructions. Look for a product that is easy to calibrate and that requires minimal maintenance.
|Automatic Temperature Compensation||Medium|
|Easy to Use||Medium|
After researching and testing various refractometers, we have identified the top options that will provide brewers with accurate and reliable readings, withstand frequent use, and are easy to use.
Digital vs. Analog Refractometers
As you have seen, there are two main types of refractometers available: digital and analog. Let’s explore the differences between these two options to help you choose!
Analog refractometers, also known as optical refractometers, have been used in the brewing industry for a long time. These devices utilize the principle of light refraction to measure the density of a liquid sample. They feature a prism or a glass plate that the liquid is placed upon, and the user reads the scale through an eyepiece to determine the specific gravity or sugar concentration.
Analog refractometers have been trusted by brewers due to their simplicity and reliability. They are relatively affordable and do not require batteries or power sources. However, they require manual interpretation of the measurement scale, which can introduce human error, especially when dealing with precise readings. Analog refractometers also tend to be less accurate and may have limitations in terms of temperature compensation.
Digital refractometers are newer innovations that have gained popularity among brewers. These devices utilize advanced optics and electronic sensors to measure the refractive index of a liquid. They often feature an LCD screen that displays the measurement in a digital format, making it easier to read and interpret.
Digital refractometers offer several advantages over analog models. They provide accurate and precise measurements, eliminating the need for manual scale interpretation. Many digital refractometers also come with built-in temperature compensation, which ensures accurate readings even when the sample temperature varies. Some models even allow for automatic temperature correction.
Additionally, digital refractometers often offer features such as data storage, automatic calibration, and the ability to switch between different measurement units. These added functionalities enhance convenience and efficiency in the brewing process. However, digital refractometers tend to be more expensive than their analog counterparts.
In summary, both digital and analog refractometers have their pros and cons in the context of brewing. Analog refractometers are reliable and affordable but may require more skill and attention during readings. Digital refractometers provide accurate measurements, advanced features, and easier readability but come at a higher cost. Ultimately, the choice between the two depends on the brewer’s preferences, budget, and desired level of precision.
