EBC Colors of Beer

EBC Color speaks about the beer color intended by the artisan brewer. In broad strokes, the artisan is expressing to you the character of the beer through a color name. But EBC color makes a distinction and creates nuance to the message.

How red is your “Red” beer against a whole bunch of reds? This is a question an EBC Color value answers for you. You will go through an elaborate flow of measurements and number crunching. For those who scowl at math, charts are available to build your intuition.

What Does EBC Measure?

In the context of beers, EBC is a standard of color measurement. You can think of it as how good your brewed beer or the beer you are buying looks.

EBC measures the change in a specific light’s properties before and after it goes through a test liquid. In your case, your favorite beer or homebrew.

How Is EBC Calculated?

If you want to calculate how impressive your brew looks, below is some math.

If you happen to own a spectrophotometer, and you understand the scientific method:

  • EBC = 25 times the Dilution Factor of the sample, multiplied by the Absorbance of light in the 430-nanometer spectrum, in a 1 cm vial.

  • EBC = 25 × D × A430

  • There are also other calculation adjustments for hazy beers and very dark beers but it might be too much.

If you have no clue what a spectrophotometer is, here is a little cheat code:

  • You can first do the Standard Reference Method (SRM) estimate based on Malt Color Units.

  • Convert the SRM to EBC color using the EBC to SRM Formula below.

EBC to SRM Formula

The conversion of EBC to SRM is as easy as doubling your SRM value. The act of doubling is just a rule of thumb though.

If you want to spend some extra brainpower, it is 1.97 times the SRM. The equation is below:

  • EBC = 1.97 × SRM

How to Increase EBC in Beer

You can increase the visual appeal of your beers by following some of the following tweaks:

  • Selecting Malts: There exists a wealth of information on grains that result in specific wort colors. Once you have decided on your base pick, you can add a few specialty grains to push the EBC in a certain direction.

  • Roasting: Roast the malts to your exact preference shade. There is no exact science to predict the outcome, so experiment with your batches.

  • Regulating pH levels: Regulate your water’s pH levels to avoid dissipating the color at low pH levels. You can add calcium carbonate to maintain your target.

  • Brewing: Longer brewing times facilitates the Maillard browning effect. It is that characteristic flavor you get with golden bread crusts, seared steaks, etc.

  • Fermenting: Yeasts during the fermentation stage can change color. Choose your yeast strain specific to your end goals.

  • Aging: The make of your beer-aging vessels will affect your beer color. You can try charred wood barrels, for instance.

EBC Beer Chart

You can check out the Beer Chart below with EBC values and sample beers. Take note that the beers have their individual color ranges and can vary wildly.

3.9 to 6.0 Straw Pilseners, Weissbier or Weizen
6.0 to 8.0 Yellow Czech Pilseners, English Blonde Ales
10.0 to 12.0 Gold White IPAs, Belgian IPAs
12.0 TO 18.0 Amber English Barleywine, Irish Red Ale.
20.0 to 28.0 Deep Amber California Common, Vienna Lager
28.0 to 34.0 Copper Roggenbier, Dunkelweizen
34.0 to 36.0 Deep Copper Baltic Porters, Schwarzbier
37-43 Brown Southern English Brown Ales, Brown Porters
43-59 Dark Brown Robust Porters, Dry Stouts
59-69 Very Dark Brown American Stouts, Russian Imperial Stouts
79++ Black Darker shades of Stouts above.

What Can Go Wrong with Using Instruments?

There are so many ways your readings can go wrong as the process can be very sensitive. Dark beers and cloudy beers require you to make calculation adjustments. If you happen to add some fruit juice to your drink, the color subtleties can get lost in the mix. Also, do not forget to clean your containers since dirt can skew your readings.

On a personal note, buying color measuring instruments will hurt your pocket. You will also need to have some level of expertise in handling said tools. It is therefore recommended that you stick to visual comparison of well-documented beers. Once you have developed the intuition and experience necessary, you can take it to the next level.
