Literature-based concentration estimates.

Further right means higher concentration. The dotted line is a published detection guide.

Original · hollowLatest · filledColor shows concentration level.

How to read the concentration scale

Each detection guide is an example of a sensory threshold reported in beer. It is a reference for noticing an aroma difference under the study conditions, not a universal boundary. Beer composition, the form of a compound and individual sensitivity can change it. A value below the guide does not mean the compound makes no contribution to the beer's aroma.

The shaded section covers concentrations below the guide. The scale uses logarithmic spacing within each section, with more room above the guide. Colors and marker sizes distinguish concentration positions, not sensory strength, beer quality or estimate accuracy. Original and Latest share the same fixed scale.

The right end is a display limit, not a sensory maximum. An arrow replaces the marker for a value outside the displayed range; the rounded amount remains visible. Increasing a concentration beyond the display limit may still change aroma intensity or character.

These published sensory references help read the concentrations. They do not validate this recipe or measure the model's accuracy. Rounding can affect which side of the guide a marker appears on.

“~” marks a rounded model estimate, not a known margin of error. “<” means below the numeric reporting floor, not a laboratory or sensory detection limit. Missing values were not recorded in older saves. Concentration bands and values below the reporting floor have no point on the scale.

Model estimates

Rounded estimates, not measurements or a guarantee of finished aroma.

Grounded in brewing research

Your ingredients and process conditions inform the estimates. Use them to explore and compare recipes.

About these estimates

Literature-based estimates, not measurements or a guarantee of finished aroma. Ingredients, fermentation and storage can change actual concentrations.

Aroma uses five bands, from subtle to very high. Equal bands can still contain differences. Original and latest show saved results, not live changes to the recipe.

Tinseth, boil additions only. Whirlpool and dry-hop bitterness are not included; the app shows the full model.
