Top 10 Best Hydrometers for Brewing in 2024

Should you be interested in making your own beer, wine, or hard cider, having a trustworthy hydrometer is indispensable. It isn’t just a necessary tool for professional brewers, but for home brewers as well. While most people might think its only function is to test alcohol content, a hydrometer actually presents a wider range of applications. It helps you assess yeast fermentation, gauge the amount of sugar in the must (the pulp or skin) in the process of making wine, and establish the end of the brewing process. To ensure a uniform quality, a hydrometer is absolutely essential.

Beer brewers often forget to calculate the ABV when they first brew beer. Experts agree that this is a mistake. Although it is easy to use a hydrometer, it can help make your life simpler. There are many brands and types of hydrometers on the market, so you might be confused when choosing one. We have created this review article to help homeowners find the best hydrometers for home brewing.

What is a Hydrometer?

Hydrometers are tools that allow you to determine how much fermentation has occurred in liquids like beer and wine. This is done by measuring the density against pure water to determine how much sugar has dissolved in the beer. A hydrometer will often come with a graduated cylindrical that allows you to pour liquid into the cylinder to measure liquid density.

The hydrometer is usually designed with a narrow stem for density measurement. Below that sits a hollowed, air-tight tube for buoyancy and weight to stabilize the device. This allows you to float the hydrometer in the beer you’ve poured into a test container. The long, thin stem will allow you to measure the amount of water that has settled. It will also have a scale. To calculate the alcohol content, you can take readings before and after fermentation.

Let’s take a look at the available hydrometers. These three types are compatible with beer, cider, wine, and mead up to 22 percent ABV.

i) Triple Scale Hydrometer

This hydrometer is the most common and the cheapest at $5-15. This hydrometer is multifunctional, measuring specific gravity, Brix/Balling, and potential alcohol. This hydrometer can measure a greater range of specific gravity (0.00-1.1770), so it is suitable for most batches. This also means that readings may be slightly off due to the fact that the device can measure a wider range of numbers.

ii) Thermohydrometer

The thermohydrometer measures temperature and specific gravity. You can have inaccurate readings due to the variability in thermometer calibrations. If you don’t use the same thermometer each time, you run the risk of getting an incorrect reading. The thermometer is built-in will ensure that your temperature remains consistent. Because you get two instruments in one, the price range of $10-15 is very reasonable.

iii) Precision Hydrometer

Precision hydrometers measure specific gravity. Numbers are placed on a smaller scale which allows for more precise readings. You may need to purchase two hydrometers depending on the type of brewing you are doing. Some hydrometers are 1.000-1.70 in size, while others are 1.060-1.130 in size. Most other hydrometers range from 0.00 to 1.70. This particular hydrometer can be purchased for $30. However, if accuracy is important to your business, it is well worth the additional investment.

Buying Guide for the Best Hydrometer For Brewing

People brew beer at home in modern times. It is possible to create delicious flavors with the help of many useful and modern equipment. You can make a drink at home that is delicious and enjoyable. This trend is well-known by many brands, which focus on high-quality tools. The best drinkable will be as delicious as the experience. We have some tips to help you make the best product.

1. Components

A hydrometer is a thin tube of glass with one or more scales on a paper or plastic insert. A larger bulb is below that for buoyancy. To calibrate and balance the instrument, a weighted plug is located at the bottom. It usually contains steel balls. The plug used to be filled with mercury or lead in the past. However, these metals can cause severe health problems and could result in the loss of your drink. Hydrometers that contain mercury or lead have not been found. However, make sure your instrument is safe.

A hydrometer is not complete without a test tube, jar, or another vessel. Most hydrometers require 250 ml (minimum) of liquid. However, some models come with a tube that requires the only 125ml. The latter will reduce the amount of waste you produce by preventing you from returning the sample to your brew.

Because of its clarity, glass is preferable. Plastic can fog up or distort. Some manufacturers offer graduated jars. However, it is easier to read the readings of the hydrometer if the jar is not marked. Tubes can be easily knocked over because they are usually very thin. To protect them from being damaged, some tubes come with a “bumper” ring.

2. Case and care

Hydrometers that are cheap can be fragile so they don’t come with a case. A hard case, or padded box, is a great addition. You can also add a brush and a cleaning cloth.

3. Certification

The National Institute of Standards and Technology (NIST) traceability/certification is a guarantee that the hydrometer was made to the same standard as a reference product that’s known to be accurate, so the certified instrument has the same level of accuracy.

4. Digital hydrometers

There are a few digital WiFi hydrometers available now. Many are intended to be part of the brewing equipment and remain in place throughout the entire process. They transmit information wirelessly to a smartphone or tablet, as well as a website. These devices provide detailed information wherever and whenever you want it. These are however expensive so they will not appeal to casual enthusiasts or professionals.

5. Prepare for the necessary equipment

To ensure a perfect brewing experience, and a delicious finished product, you need to be careful. You will need a stirring spoon, tongs, and a pump. A strainer and funnel are also necessary for fermentation. A consistent temperature hydrometer is also necessary to calculate.

The bottling equipment is crucial in the final step. You can use it with your home-brewing beer kit. For fermentation, keep the product in a dark and dry place. It could take up to 2-4 weeks.

6. Clean the equipment

Brewing beer at home requires many steps. All of them are crucial. You must ensure that the tools and ingredients are fresh and clean from the beginning. This will ensure that you get the best beer taste and a healthy environment. Before and after each use, clean the product. Next, rinse out all sanitizers.

To prevent bacteria from growing during fermentation, you will need to prepare a sealed container. The kettle must be large and clean.

7. Pay attention to temperature and time

Brewing beer is a time-consuming process. A thermometer and a timer are two things you may need when making beer. It is important to pay attention from the beginning to temperature and time. 170°F is too high. You need to keep it below 170°F. Beer will go sour if it does.

Frequently Asked Questions

1. What is specific gravity?

It is the ratio of a substance’s density to that of a standard. It can be used to describe liquids, gases, and solids. It is the ratio of alcohol to water for winemakers and brewers. To calculate the alcohol content (ABV), you can use specific gravity. This is done by measuring before fermentation (original gravity) and after fermentation. ABV = OG-FG /.00753. Although it isn’t scientifically exact, it’s good enough for home brewers.

2. Do I need another hydrometer to distill spirits?

While a beer/wine hydrometer can be used for the initial mash you will need a Proof and Tralles hydrometer to assess alcohol content after distillation. The standard triple-scale hydrometers typically read at 35% alcohol. This is often not enough to handle spirits or liquors. The larger scales are less accurate than those required for winemaking or brewing, so they cannot be interchanged.


When choosing the best hydrometer to use for brewing, the most important thing is its accuracy. We chose the most popular hydrometers because they have great performance.

A hydrometer is a great tool for home brewing. It can accurately calculate ABV, measure sugar content, complete fermentation, and create your favorite brews with greater consistency. A hydrometer allows you to have greater control over the entire process of brewing, which will give you more control over the final product.

These criteria make the Chefast Hydrometer the best wine-hydrometer on the market. This instrument comes in a set that includes a plastic test container, a cleaning brush, and a storage bag. The hydrometer has a triple scale and can be used to grade wine and beer.
