High gravity beer is beer with a high alcohol content by volume (ABV). Generally, large breweries make beer with ABV of 4.0 to 6.0 percent, while high gravity beers can exceed that range. This type of beer is sometimes called “imperial,” “double,” or “extreme” beer by individual brewers.
Some of the most well-known high gravity beers have an ABV of up to 18.0 percent, or even higher. While there are some national commercial brands of high gravity beer, most of it is brewed in small batches by craft brewers.
High gravity beers come in all sorts of styles, including pale ales, stouts, IPAs, sours, and Belgians. When consumed responsibly, they can be a great way to enjoy complex flavors and aromas from bold ingredients that you can’t find in any other type of beer.

What makes a beer high gravity?
A beer’s gravity is determined by its original wort, which is the unfermented beer that comes out of the mash tun. This original wort’s gravity is measured as the ratio of the density of the liquid to that of pure water, usually expressed in the Plato or Balling, or the more usual Brix measurements.
When the wort is boiled and the hops are added, the gravity becomes higher. This is because the boiling causes some of the sugars to evaporate, leaving a higher concentration of sugars (aka dissolved solids) behind.
So, a beer’s final gravity is always higher than the original gravity.
A high gravity beer is one that has an original gravity of 1.050 or higher. This means that it has a higher concentration of sugars and is heavier than other beers with a lower original gravity. A high gravity beer may be either fermented or unfermented and the resulting beer will have a thicker body and a higher alcohol content than lighter beers.
So, by definition, a beer with a high gravity will be higher in alcohol and heavier than a beer with a lower gravity.
What if my original gravity is too high?
If your original gravity is too high, there are several things you can do to modify it. The most common remedy is to lower the amount of malt in your recipe, either by reducing the amount of grains or substituting them with lower gravity malts.
If you reduce the amount of grain significantly, you may need to adjust the amount of water accordingly since a larger grain bill requires more water. You can also add unfermentable sugar or sugar syrup to your wort to lower the gravity without changing the overall character of the beer.
Lastly, if your fermentation temperature is too high, it can cause an over-attenuation resulting in a higher-than-expected gravity reading. In this case, you can try lowering the temperature (within proper parameters) or adding a healthy yeast starter to get the fermentation back on track and achieve the desired gravity reading.
What is a good specific gravity for beer?
The typical range of specific gravities for beer lies between 1.035 and 1.070. Generally speaking, the higher the specific gravity, the higher the alcohol content of the beer. The specific gravity for a beer also affects taste, so when aiming for a specific alcohol content and flavor, a brewer will have to work to find the right balance of water to grain.
Furthermore, some beers such as lagers or light beers will have a lower specific gravity, while ales and stouts are typically higher. When the specific gravity is appropriate for a particular style, brewers will use it as one of the criteria to determine if the beer is ready to be bottled or kegged.
Does high-gravity mean high alcohol?
No, high-gravity does not necessarily mean high alcohol. Gravity is a measure of the density of a liquid, with higher gravity reflecting a denser liquid. Alcohol is denser than water, but other substances like sugars and syrups can also contribute to higher gravity.
Commercial beer and liquor are typically associated with a higher gravity, but the overall alcohol content can still vary depending on the recipe and brewing process. For example, a beer with a high gravity could still have an ABV (alcohol by volume) of only 5%, or even as low as 2.5%.
Similarly, beverages with a lower gravity can still have a high ABV of 10-12%. So, high gravity does not necessarily mean high alcohol.
Do higher ABV beers take longer to ferment?
Generally, yes, higher ABV beers take longer to ferment than lower ABV beers, but there are a few factors that need to be taken into consideration before giving a definitive answer. The time it takes for a beer to ferment can depend on the style of beer, the type of yeast used, and the temperature of the fermentation environment.
For example, some yeast strains are more efficient at converting sugar into alcohol and will ferment a beer faster than other strains, giving the same results while taking less time.
A beer with a higher ABV will require more sugar to be added to the brewing recipe, which will take more time for the yeast to convert into alcohol. In addition, the temperature of the fermentation environment is an important factor.
High temperatures can significantly reduce fermentation times, whereas low temperatures can lead to slower fermentations, as well as off-flavors and aromas.
Ultimately, it is important to know the type of yeast used, the temperature of the fermentation environment, and other factors related to the beer recipe, in order to determine how long it will take for a higher ABV beer to ferment.
How do you increase the final gravity of beer?
The gravity of beer, or the density of the liquid, can be affected by many factors during the brewing process. The density of the beer is measured by the Specific Gravity (SG), which provides the ratio between the density of a liquid, in this case wort, and the density of water.
The higher the SG, the higher the gravity of the beer. The Original Gravity (OG) is determined when the wort is first created, and the Final Gravity (FG) is determined when the yeast has finished fermenting the beer.
Add more malt: Adding more malt to your beer can increase the final gravity, as malt gives your beer the sugars needed for fermentation. Be sure not to add too much, as it could make your beer too sweet.
2. Utilize a yeast strain that is known to produce high FG beers: Certain yeast strains, such as lagers, will naturally have a higher FG.
3. Reduce the attenuation of the yeast: Attenuation is the process of yeast converting the sugars in wort into alcohol and carbon dioxide. Reducing this process can help increase the FG of your beer.
4. Be patient: Allowing your beer to ferment for a longer period of time can increase the final gravity.
5. Reduce the temperature of the fermentation: Colder temperatures tend to slow down the process of fermentation, allowing the yeast more time to convert the sugars into alcohol and carbon dioxide. This will leave more sugar in the beer, increasing the gravity.
Following these steps can help increase the Final Gravity of beer, resulting in a smoother, fuller-bodied beer.
How long does a high gravity beer take to ferment?
The length of time it takes for a high gravity beer to ferment can vary greatly depending on the strain of yeast used, the temperature of the fermentation, and the complexity of the recipe. Generally speaking, high gravity beers such as Imperial Stouts, Barleywines and Doppelbocks can take up to four weeks or longer to complete fermentation.
During the fermentation process however, the beer can be transferred or ‘racked’, or have additional ingredients or adjuncts added to the wort, which can also extend fermentation time.
If the yeast is a primary factor in the length of the fermentation process, the strain of yeast used can also play a key role. Generally, the strain of yeast used will determine the amount of time it takes for fermentation to complete.
For instance, a lager yeast will take significantly longer (often weeks) than an ale yeast strain.
Finally, the complexity of the recipe and the temperature of the fermentation will also influence the length of time it takes for the high gravity beer to ferment. The higher the gravity of the beer, or the more complex the recipe, the longer it can take for fermentation to complete.
Similarly, lower temperatures and cooler fermenting temperatures tend to result in a longer fermentation time.
In summary, the length of time it takes for a high gravity beer to ferment depends largely on the yeast strain used, the complexity of the recipe, and the temperature of the fermentation. On average, a high gravity beer can take up to four weeks or longer to finish fermentation.
What does gravity mean in beer?
If you’ve ever seen a beer tap, you know that beer is stored in a keg under pressure. The pressure inside the keg is greater than the atmospheric pressure outside the keg. This difference in pressure creates a force on the beer inside the keg that wants to push the beer out of the keg.
In order for the beer to stay in the keg, the keg must be placed on a surface that is able to provide an opposing force that is greater than the force created by the pressure difference. This opposing force is gravity.
The force created by the pressure difference is typically referred to as “carbonation pressure. ” The amount of pressure created by the carbonation in the beer is dependent on the amount of carbon dioxide that has been dissolved into the beer.
The more carbon dioxide that is dissolved into the beer, the higher the carbonation pressure.
Gravity is the force that is created by the mass of an object. The more mass an object has, the more gravity it has. The gravity of an object can be measured by its weight. The weight of an object is the force of gravity on that object.
The force of gravity on a beer keg is the weight of the keg. The weight of the keg is the force of gravity on the beer inside the keg. The gravity of the beer inside the keg is what keeps the beer in the keg.
If you were to take a keg of beer and place it on the Moon, the beer would not be under the same level of gravity as it is on Earth. The gravity on the Moon is only about 1/6th of the gravity on Earth.
This means that the force of gravity on the beer inside the keg would be only 1/6th of the force of gravity on the beer on Earth. The beer would easily be able to push itself out of the keg and float around in the zero gravity environment of the Moon.
How do you read alcohol gravity?
Reading and understanding alcohol gravity is an essential step for any homebrewer or commercial brewer. Alcohol gravity is essentially a measure of the density of the beer and is expressed in terms of the specific gravity (or the ratio of the density of the liquid to that of water).
To read alcohol gravity, you will need either a hydrometer or a refractometer. Both of these devices are relatively easy to use – a hydrometer is simply a tube filled with liquid that is then placed into your beer sample, while a refractometer needs a small sample of wort or beer and a few drops of water.
In a basic hydrometer, a numerical value known as “sugar gravity” is given at the bottom of the scale. This reflects the amount of sugar present in the beer and the numerical value is the ratio between the density of the beer and the density of water.
A refractometer reads your beer sample in the same way, but instead of a number it gives you a chart of results that print out.
Once you have the numerical value for your beer sample, you can then use this to calculate the alcohol content. To do so, simply subtract the starting gravity from the ending gravity. The result is the amount of alcohol present in the brew.
Knowing your gravity readings is key to brewing quality beer. With this knowledge, you can adjust the recipe accordingly and help ensure the finished product is exactly what you intended it to be.
When should I start reading gravity?
It’s never too early to start reading Gravity! Reading Gravity is beneficial for children of any age, as it helps to reinforce their understanding of the world around them and develop their reading comprehension.
However, for younger children, it is best to start reading Gravity when they are ready to understand and engage in the content. Reading Gravity may be appropriate for children aged 4-5 if they are strong readers, or 5-6 if they are emerging or beginning readers.
When preparing to read Gravity with your child, select a level appropriate for their reading skills and check that they understand the basic concepts behind the story.
What is a good hydrometer reading?
A good hydrometer reading for beer would generally mean that the beer is fermented and ready to be enjoyed. Depending on the beer style, the reading should typically range from 1.010 to 1.020, with the ideal range being 1.010-1.
014 for most lagers, 1.015-1.017 for most ales, and 1.015-1.018 for Belgian and other specialty beers. These numbers indicate the gravity of the beer and essentially represent the amount of dissolved sugars in the beer after the fermenting process is complete.
Higher hydrometer readings usually indicate higher alcohol content and more residual sugar, while lower readings indicate that the fermenting process has left less sugar behind and there may be less alcohol content.
To get a precise reading, a hydrometer sample should be taken between 76-79 degrees Fahrenheit and should be marked as “finished beer” on the hydrometer.
How is beer gravity measured?
Gravity is a measure of the amount of fermentable sugar in a beer, and it is typically measured in gravity points or °Plato. This is important to measure because in order to convert the sugars into alcohol, the yeast needs the fermentable sugar; the higher the gravity of a beer, the higher the potential alcohol content.
Gravity is determined by taking a pre-boil wort sample and measuring it with a hydrometer, which is a device that measures the specific gravity of the liquid. A hydrometer measures the relative density of a liquid compared to water and is calibrated to read 1.
000 in pure water. To calculate the gravity of the wort, the difference between the final gravity (FG) and the original gravity (OG) is measured in points. OG is measured before fermentation, and FG is measured after fermentation is complete.
The formula for calculating the gravity of beer is:
Original Gravity (OG) minus Final Gravity (FG) times 1000 = Gravity Points.
For example: if your OG was 1.090 and your FG was 1.030, then 1.090 – 1.030 = 0.060 multiplied by 1000 = 60 gravity points. So, the gravity of the beer in this example is 1.060.
How do you calculate hydrometer readings?
To calculate hydrometer readings, you will need a few items: a hydrometer, a temperature-compensating tool, a graduated cylinder and a sample of the sample liquid.
Begin by using the temperature-compensating tool to adjust the hydrometer according to the temperature of the sample fluid. When making the adjustment, it is important to make sure that the hydrometer is floating freely and is not touching the sides of the cylinder.
Once the temperature has been accounted for, fill the graduated cylinder with the sample liquid and make sure that the hydrometer is submerged in the liquid. After it has settled, look for the closest value for the surface of the liquid on the hydrometer.
This is the initial hydrometer reading. Also, make sure to note the temperature that was used for the temperature compensating tool to ensure accuracy.
When the hydrometer is removed from the fluid, take the additional reading that appears on the stem of the hydrometer. This is the second and final hydrometer reading. To get the true hydrometer reading, subtract the second reading from the initial hydrometer reading, and then use the temperature-compensating tool to make any additional adjustments needed due to temperature changes.
Once you have made all of the correct calculations, the hydrometer reading should provide the most accurate representation of the weight and specific gravity of the sample liquid.
What is the alcohol content of beer in Tennessee?
The alcohol content of beer in Tennessee is determined by the Tennessee Alcoholic Beverage Commission. Generally, beer in Tennessee must contain not greater than 6.15% alcohol by volume, making it slightly lower than the national average of 6.2%.
The Tennessee Alcoholic Beverage Commission enforces alcohol and public safety laws in the state and has the authority to issue alcohol licenses, as well as regulate and enforce the amount of alcohol contained in beer, wine and spirits.
What beer is Tennessee known for?
Tennessee is best known for its abundance of craft breweries producing a wide variety of beer styles. From Nashville to Memphis to Gatlinburg, there are countless breweries crafting local lagers, pale ales, IPAs and sours.
Craft beer has become particularly popular in recent years, so much so that the state has established an official Tennessee Beer Trail. The breweries on the trail vary in size and offer different house-made beers and unique flavors.
Many of these beers are made with local ingredients, including honey, apples, and cherries. Some of the state’s most popular breweries include Boscos, Yazoo, and Blacksmith Brewing Company. Tennessee is also home to some classic larger-scale brewers, such as Anheuser-Busch InBev.
All of these beers are made right here in Tennessee, consolidating the state’s standing as a great place to find a variety of beers.
Is high gravity beer malt liquor?
No, high gravity beer is typically not malt liquor. The terms are often confused because both refer to beers with a higher alcohol content than regular strength beer. However, the difference lies in the categories of malts and grains used to brew each.
High gravity beer is brewed with malts and grains that are higher in fermentable sugars than regular strength beer, resulting in a higher alcohol content. Malt liquor, on the other hand, is brewed with malts and grains that are lower in fermentable sugars.
As a result, the malts and grains do not contribute to the alcohol content, so the alcohol content of the malt liquor is derived from the added additional alcohol by the brewer, typically from the addition of corn syrup.
How do you get high OG beer?
To get high-OG beer, you’ll need to brew a beer with lots of malt, since mashing more grains together will produce a higher original gravity reading. One trick is to use relatively plain but high-gravity ingredients such as Munich and Vienna malts, as these contain a lot of fermentable sugars that will result in a higher OG.
You can also try adding specialty grains like crystal or chocolate for extra flavor. Most importantly, though, you should make sure to use a good quality yeast suited for high-gravity beers that can process all the extra sugars and ferment out all the alcohol.
Finally, use a yeast nutrient supplement and make sure to keep the fermenting temperature at the lower range of the yeast’s acceptable range. Following these steps should help you brew a high OG beer.
