Flavor Compass

Perception before diagnosis

Accessible data / interpretation
  • Aroma
  • Taste
  • Mouthfeel
  • Appearance
  • Trigeminal
  • Integrated

A sensory descriptor is an observation, not proof of chemistry, process fault, contamination, or quality.

Generation B · Flavor Compass

Start with what you perceive, then trace what might connect

A sensory vocabulary and evidence graph spanning aroma, flavor, mouthfeel, appearance, trigeminal sensation, and integrated impressions. The compass separates perception from chemistry, cause, quality judgment, and preference.

  • 20 foundation descriptors
  • 6 perceptual sectors
  • Possible causes ≠ diagnosis

Causal clarity

Perception → possible causes → style context

BEU008 keeps sensory identity separate from the things that may create it.

Sensory word

“Buttery” is a perceptual descriptor.

Possible chemistry

Diacetyl can contribute buttery character, but perception is not a compound assay.

Process context

Maturation can change diacetyl-related expression; that does not make one schedule universally correct.

Style context

A descriptor may be expected, tolerated, neutral, or unwanted depending on style and threshold.

Compass sector 10

Taste & Flavor

Taste-led and flavor descriptors used to navigate balance and recognizable character. Sensory identity is not an analytical measurement, IBU value, pH value, or recipe target.

taste

Bitterness

A taste-related bitter sensory descriptor whose perceived intensity and balance depend on composition and context.

flavornot a fault by identity

taste

Sourness / Acidity

A sour or acidic taste impression; perceived sourness is related to but not identical with analytical acidity or pH.

flavorcontextual only

taste

Sweetness

A sweet taste impression arising from the beer matrix; not interchangeable with measured residual extract.

flavornot a fault by identity

Compass sector 20

Aroma

Orthonasal and aroma-led character families, with secondary flavor modalities retained where relevant. An aroma word does not identify a molecule, organism, ingredient, or fault by itself.

aroma character

Banana-like

A banana-associated aroma/flavor descriptor often linked in brewing literature with ester chemistry, while remaining a sensory identity rather than a compound identity.

aromacontextual only

aroma character

Buttery

A butter-like aroma/flavor descriptor often discussed in relation to diacetyl, while remaining perceptually and contextually distinct from the compound itself.

aromathreshold dependent

aroma character

Citrus-like

A citrus-associated aroma/flavor descriptor that can arise from hop and fermentation contexts among other sources.

aromanot a fault by identity

aroma character

Clove-like

A clove-associated spicy phenolic aroma/flavor descriptor. The descriptor is perceptual; chemical or microbial links are modeled separately.

aromacontextual only

aroma character

Floral

A flower-associated aroma descriptor with ingredient- and fermentation-dependent expression.

aromanot a fault by identity

aroma character

Fruity

A broad fruit-associated aroma/flavor family used as a perceptual parent for more specific fruit-like descriptors.

aromacontextual only

aroma character

Papery / Cardboard-like

A paper- or cardboard-associated aroma/flavor descriptor commonly used in beer staling and oxidation discussions.

aromacommonly fault language

aroma character

Resinous / Piney

A resin- or pine-associated aroma/flavor descriptor frequently used in hop-forward contexts.

aromanot a fault by identity

aroma character

Roast-like

A roasted, dark-grain-associated aroma/flavor descriptor; intensity and desirability depend strongly on style and recipe context.

aromacontextual only

aroma character

Sulfurous

A broad sulfur-associated aroma family whose source and acceptability depend on compound, concentration, process, and style context.

aromathreshold dependent

Compass sector 30

Mouthfeel

Texture, fullness, drying, and other physical impressions perceived in the mouth. Mouthfeel descriptors are perceptual and must not be substituted for laboratory values.

mouthfeel texture

Astringency

A drying, puckering mouthfeel sensation; source and quality meaning depend on concentration and brewing context.

mouthfeelthreshold dependent

mouthfeel texture

Body / Fullness

A mouthfeel impression describing perceived fullness or weight in the mouth, separate from analytical gravity.

mouthfeelnot a fault by identity

Compass sector 40

Appearance

Visible attributes such as clarity and haze without ranking one presentation as universally superior. Appearance can be intentional, traditional, neutral, or quality-relevant depending on context.

appearance attribute

Clarity

An appearance descriptor for visual transparency or brilliance; it is not a universal quality requirement.

appearancecontextual only

appearance attribute

Haze / Cloudiness

A visible appearance descriptor describing suspended or diffuse material that reduces clarity.

appearancecontextual only

Compass sector 50

Trigeminal

Warming, prickling, and other chemically or physically mediated sensations beyond basic taste and aroma. Trigeminal sensation is not a proxy for intoxication, ABV, or safety.

trigeminal sensation

Carbonation Prickle

A tactile/trigeminal prickling sensation associated with dissolved carbon dioxide and carbonation presentation.

trigeminalnot a fault by identity

trigeminal sensation

Warming

A trigeminal warming sensation that can be associated with ethanol and other contextual factors.

trigeminalthreshold dependent

Compass sector 60

Integrated Impressions

Editorial/sensory impressions that combine multiple perceptual cues into a useful exploration term. Integrated terms such as crisp are not single measurable variables or universal quality scores.

integrated impression

Crisp

An integrated impression often combining restrained sweetness, firm structure, and a clean or refreshing finish; not a single measurable sensory variable.

overallcontextual only

Fault language

Context before verdict

13 foundation descriptors explicitly carry contextual or threshold-dependent fault-use metadata. “Off-flavor” language never converts automatically into a universal defect label.

Sourness / Acidity

Sourness can be defining in some beer styles and undesirable in others. The descriptor does not establish acid identity, pH, contamination, or defect status.

Banana-like

A perceptual descriptor only. Presence, intensity, desirability, and quality meaning depend on beer, threshold, process, and style context.

Buttery

Buttery character is often fault language when prominent, but threshold, style, maturation, and sensory context matter. Detecting it does not by itself prove a specific cause.

Clove-like

Clove-like character can be expected in some fermentation traditions and unwanted in others. The descriptor itself is neither praise nor defect.

Fruity

A perceptual descriptor only. Presence, intensity, desirability, and quality meaning depend on beer, threshold, process, and style context.

Papery / Cardboard-like

Papery/cardboard-like character is commonly used as staling/off-flavor language, but perception alone is not sufficient to identify a single chemical or process cause.

Roast-like

A perceptual descriptor only. Presence, intensity, desirability, and quality meaning depend on beer, threshold, process, and style context.

Sulfurous

“Sulfurous” is a broad sensory family, not a diagnosis. Different sulfur compounds can smell different, and some low-level sulfur expression can be process- or style-contextual.
