Best Hydrometers for Homebrewing(Review 2023) – 3 types of hydrometer will help you determine the alcohol content in beer
Using a hydrometer is often overlooked by newcomers to the world of homebrewing. However, this step is painless to build in, easy once you know how and can save a batch from getting ruined. It also helps you know how much fermentation has taken place and can be used to help you determine the alcohol content of your beer by taking readings before and after fermentation. But what exactly is a hydrometer and how do you use one?
In this post, we will outline the answers to these questions, look into what considerations you need to make when buying a hydrometer by looking at the benefits or otherwise of the different types, and introduce you to some of our favorite hydrometers for different brewing processes and budgets. By the end, we hope we will have convinced you that using a hydrometer is an essential part of the brewing process for any homebrewer.
What is a hydrometer?
A hydrometer is a tool that can be used to measure how much fermentation has taken place in liquids such as beer and wine. When brewing beer this involves measuring how much sugars have dissolved in the wort by measuring the density of the wort against the density of pure water. Hydrometers will usually come with a graduated cylinder where a test liquid is poured to take a measurement for liquid density.
Hydrometers are usually shaped with a narrow stem to measure density underneath which sits a hollowed air-tight glass tube for buoyancy and a weight for stabilization. You then essentially float this in your beer that you have poured into a test jar and wherever the hydrometer settles you will be able to take a measurement from the long thin stem part which will have a scale printed on it. You can use readings taken before and after fermentation to calculate the alcohol content.
How do you use a hydrometer?
The good news is that using a hydrometer is actually a simple task once you’ve learned how. This means building this step into your brewing process is easy so long as you follow the golden rule of brewing beer – always sanitize your equipment! Once your hydrometer is sanitized all you need is a tube half full of the liquid you wish to measure. If this liquid is wort, then this can be extracted from your fermenter using a sanitized tool or, ideally, through your fermenter’s in-built spigot.
Now you are ready to take your measurement. Gently place your hydrometer into your tube of wort (which should be cooled) and allow it to float on its own. Once it has settled in place take a reading of where the liquid in your tube covers the scale on the stem of your hydrometer. Given you want to measure changes over time it is handy to have a diary or a pad of paper wherever you tend to take your measurements so you don’t have to keep these numbers in your head.
It is also a good idea to take only the readings you need to at set times to reduce the amount of waste drawn-out form your brew, ultimately you want to taste your beer not measure it. The key times to take readings are:
#Step 1 Before fermentation begins
#Step 2 When you think your beer may have finished the fermentation stage (or be nearing it)
#Step 3 2-3 days later take a further reading
#Step 4. If the reading had changed at step 3 take a further reading daily until you notice no change
How to calibrate a hydrometer
As with any measuring device, it is important to calibrate it regularly. Fortunately, it is easy to test whether your hydrometer’s accuracy is on the wane by placing it in purified water at room temperature. If you get a reading of 1.000, then you are fine to take the readings of your hydrometer at face value. Otherwise, for every point difference you will need to adjust your readings accordingly (eg. if it reads 1.001 you will need to add 0.001 to other readings). If you cannot wait for your wort to cool to room temperature, you will need to adjust your readings for this either by using a hydrometer temperature correction calculator or following the instructions that came with your hydrometer.
How to choose a hydrometer for brewing beer: understanding the different types of hydrometers
There are different types of hydrometers available that range in sophisticated and price range. In this section, we go through the three different types of hydrometers that you will come across.
A thermohydrometer contains a thermometer and measures temperature as well as specific gravity. With an inbuilt thermometer, this makes it easy to correct the temperature of the sample when you read the specific gravity and ensure that a consistent temperature is maintained. You can expect to pay between $10 and $15 for this type of hydrometer.
#2 Triple Scale Hydrometer
Triple scale hydrometers are the most commonly used hydrometers in the world of homebrewing and they are also the most affordable (starting from around $5). It has multiple functions and can measure Brix/Balling scale, specific gravity, and alcohol content. With a triple scale hydrometer, you will be able to measures a large range of specific gravity so you will be able to use it for most batches you brew.
#3 Precision Hydrometer
As the name suggests a precision hydrometer gives a more precise reading when measuring specific gravity. It can do this because the numbers are spaced out on a smaller scale on the hydrometer so a more accurate reading can be taken. For this reason, precision hydrometers measure a smaller range of gravity levels so you may need to purchase two hydrometers for certain batches of beer. Precision hydrometers are the most expensive type of hydrometer, costing around $30 apiece. They are a good investment if you want to ensure the readings taking are as accurate as possible.
