The International Bitterness Units scale, or IBU, is used to approximately quantify the bitterness of beer. This scale is not measured on the perceived bitterness of the beer, but rather the amount of iso-alpha acids.
How do you measure bitterness in beer?
The overall bitterness of beer can be determined by extracting an acidified beer solution into isooctane followed by measuring the absorbance at 275 nm. The absorbance is then multiplied by 50 to obtain the bitterness in BU.
What is the IBU of an IPA?
American mass market lagers have typical IBU ranges of 5 to 10 IBUs, Bavarian hefeweizens 8 to 12 IBUs, amber lagers 20 to 25 IBUs, American pale ales 35 to 40 IBUs, American India pale ales (IPAs) 55 to 70 IBUs, and “double IPAs” and American barley wines 65 to 100 IBUs.
What does IBU mean in craft beer?
“International Bitterness Units are a chemical/instrumental measurement of the number of bittering compounds, specifically isomerized and oxidized alpha acids, polyphenols, and a few other select bittering chemicals, that make your beer taste bitter.
Can an IPA have low IBU?
USUALLY (there are exceptions) the lower the IBU’s the less “hoppy” its going to be. One of the notable exceptions is Hop Stupid, 102 IBU’s but not really bitter or strong, as it has a nice malty balance.
How do you measure IBU in beer?
Here is a quick formula for determining International Bitterness Units (IBUs) from Fred Eckhardt: For a 5 gallon batch of homebrew, you take Ounces x Alpha Acid x Percentage Utilization(boil time) divided by 7.25.
Is 70 IBU bitter?
Try again: A beer’s bitterness is gauged by its International Bittering Units (IBU). Your standard Budweiser has 7 IBU, while Avery’s IPA has 70 and the Maharaja, an imperial IPA, has right around 100. Bittering hops get added early on in the boil.
What is considered high IBU?
There are documented beers that have rated to over a 1000 IBU’s, but it’s rare to see anything nearly that high. Almost all the beer you’re ever going to drink will have an IBU rating between 5 and 120. 5 having a very low measured bitterness and 120 having a very high measured bitterness.
What IBU is considered bitter?
Generally speaking, beers with IBU of less than 20 display little to no hops presence. Beers with IBU from 20 to 45, the most common range, reveal a mild to pronounced hops presence. Heavily hopped beers with IBU greater than 45 can taste quite bitter.
How many IBUs does a Guinness have?
For the sake of comparison, Budweiser has 4.8 percent alcohol by volume (ABV) and 9 IBU; Guinness Draught has 4.2 percent ABV and 45 IBU. Sweet or cream stouts: Sweet stouts, like Samuel Adams Cream Stout, have a full-bodied mouthfeel and less of the bitter flavor associated with stout.
What is the IBU of Stella Artois?
Euro Pale Lager | ABV: 5.2 % | IBU: 30.
What beer has the most IBUs?
Dogfish Head claims that Hoo Lawd is the highest IBU beer ever made that has been independently lab tested—most of the other IBU numbers below are based on in-house calculations. Like with Scoville Units, most brewers just estimate a number, usually well above what is technically thought to be even possible.
How many IBU are in a Bud Light?
14 IBU. Bud Light ♦ 4.2% ABV.
Are Hazy IPAs less bitter?
But a Hazy IPA is far more than looks. The careful planning of malt and hops, along with less filtering before packaging, yields a beer with lower perceived bitterness than other IPAs and hop character that’s decidedly fruity—you’ll often hear “juicy” as a flavor descriptor, like a tasty bite of ripe citrus.
What makes IPA bitter?
Bitter is certainly a major factor when tasting an IPA, as the style employs an increased amount of hops which can add what is often described as evident, bracing and even aggressive bitterness.
Are double IPAs less bitter?
It’s not an easy balance to find, but if you get it right, a double IPA gives you more of everything. They take longer to brew, they offer more hoppy bitterness, they have deeper malty undertones…and they contain more alcohol – double IPAs usually come in at around the 7.5-10% ABV mark.
How do you calculate Bitterness Units?
The Bitterness Units are just the calculated IBUs of the beer. The Gravity Units are what you get when you subtract one from the Original Gravity and then multiply by 1000.An example: RAA = (OG-FG)/(OG-1) RAA = (1.050-1.010)/(1.052-1) RAA = . 040/. 050 = . 80 or 80%.
How is beer strength measured?
Formula for Calculating Alcohol in Beer Subtract the Original Gravity from the Final Gravity. Multiply this number by 131.25. The resulting number is your alcohol percent, or ABV%.
What does lovibond mean?
Lovibond also known as degrees lovibond or abbreviated as L is a scale for measuring color originally introduced by Joseph Lovibond in the 1860’s. The original Lovibond scale was used to measure gas colors, but has since expanded to measure the colors of oils, chemicals, foods and beverages.
Is 30 IBU a Hoppy?
An IBU, for the uninitiated, is a unit of measure of the bitterness of beer, which comes from hops. The more hoppy the beer, the higher the IBU. A beer’s IBU is derived from a complicated formula and is typically way below 100, with blonde ales rating around 15 to 30 IBUs and stouts, like Guinness, going up to 60 IBUs.
What is IBV in beer?
Alcohol by Volume (ABV) ABV is the most common measurement of alcohol content in beer; it simply indicates how much of the total volume of liquid in a beer is made up of alcohol. During beer’s fermentation process, yeast eats the sugar made from malted grain and then converts it into alcohol and CO2.
What beer is bitter?
Bitter belongs to the pale ale beer style and can have a great variety of strength, flavour and appearance, from dark amber to a golden summer ale. It can be under 3% abv and as high as 7% with premium or strong bitters.

Lager | ABV: 4.6% | IBU: 22 | SRM: 2.5.
What is the IBU of Blue Moon?
Wheat Ale | ABV: 4.6% | IBU: 11 One of our occasional brewpub exclusives.
What is the IBU of Sierra Nevada Pale Ale?
Sierra Pale clocks in at 38 IBUs, a number that might seem impossibly low to some of today’s drinkers.
