Study Guide

Read the full study guide: Understanding SRM

Exam Focus

  • Define ABV, IBU, SRM, original gravity, final gravity, and attenuation.
  • Use numbers to frame expectations without replacing sensory judgment.
  • Compare styles using parameter ranges and balance.

What to know

ABV describes alcohol strength, IBU estimates bitterness, and SRM describes beer color.

How it applies

Numbers support expectations but do not replace tasting because sweetness, body, carbonation, and finish affect how strength, bitterness, and color are perceived.

  • ABV and ABW describe alcohol content.
  • IBUs are associated with measured bitterness compounds.
  • SRM describes beer color.

Certified Cicerone® Notes

Style as an evaluation tool

Beer styles describe recurring combinations of aroma, flavor, appearance, mouthfeel, strength, bitterness, color, ingredients, fermentation profile, and historical context. They are not quality scores. A flawless beer can be out of style, and a beer can fit a style while still having a service or freshness problem.

Comparison framework

| Evidence type | What it tells you | Example use | | --- | --- | --- | | Quantitative parameter | Strength, color, bitterness, gravity, attenuation | Separate ordinary bitter from strong bitter | | Sensory descriptor | Malt, hop, fermentation, roast, acidity, mouthfeel | Separate porter from dry stout | | Process and ingredient clue | Yeast, malt, hopping, water, fermentation temperature | Separate German wheat beer from American wheat beer | | Historical or regional context | Traditional family and classic examples | Explain why Czech lager differs from German pils |

Professional judgment

The strongest Cicerone® answers avoid one-clue identification. Color alone does not define stout, bitterness alone does not define IPA, and fruitiness alone does not define Belgian ale. Use multiple pieces of evidence, then state the most likely style and the traits that would confirm or weaken that conclusion.

Worked style comparison

Use measured style parameters in comparison rather than as trivia. For example, when deciding between two pale lagers, combine color, malt profile, hop bitterness, fermentation cleanliness, strength, finish, and regional tradition. If the evidence conflicts, state which traits are decisive and which are weak. This habit keeps style work aligned with BJCP 2021: guidelines describe expected ranges and sensory profiles, while the taster still judges the actual beer in the glass.

Exam Focus

  • ABV and ABW describe alcohol content.
  • IBUs are associated with measured bitterness compounds.
  • SRM describes beer color.

Why It Matters

  • Style knowledge supports tasting, written explanations, purchasing, and guest recommendations.
  • Comparison by evidence prevents shallow label memorization.
  • BJCP 2021 gives a common framework for project style study.

Practical Sensory Exercises

Quantitative Parameters of Beer Character observation drill

Taste two commercial beers with different expressions of quantitative parameters of beer character. Record appearance, aroma, flavor, mouthfeel, likely source, and whether the character is appropriate for the stated style.

Key Terms

ABV
Alcohol by volume; the percentage of alcohol in beer.
IBU
International Bitterness Units; a measurement related to hop bitterness.
SRM
Standard Reference Method; a scale used to describe beer color.
Style guideline
A structured description of expected sensory profile, parameters, ingredients, and context for a beer style.
Attenuation
The degree to which fermentation reduces wort sugars, affecting body, sweetness, and alcohol.
Classic example
A commercial beer widely used to illustrate a style's expected profile.
