  • To define styles
  • To detect problems and improve your own or someone else’s beer
how to evaluate beer
“How to” evaluate beer
  • Beer can be evaluated using the flavor profile as a guide to step through the process
  • The most obvious (and the real bottom line) is the taste.
  • Before that, however, you must train all your senses to notice additional aspects that may help identify certain characteristics
flavor profile
Flavor Profile
  • Appearance (Visual examination)
  • Aroma/Bouquet (Olfactory examination)
  • Taste (In the mouth examination)
  • Overall impression (General quality)
use all six senses
Use all six senses
  • Sight
  • Hearing
  • Smell
  • Taste
  • Touch and feel
  • “Pleasure”
overview
Overview
  • Sophisticated equipment can be used to measure, down to the last molecule, the chemical breakdown of your beer
  • Technology may augment, but cannot replace, the objective and subjective findings of a trained evaluator
  • The human senses of taste, smell, sight, hearing, and touch can be trained as effective tools to evaluate beer
  • It all starts with an understanding of what each sense can give you and how they relate to the flavor profile
sight
Sight
  • Head space in the bottle
  • Surface deposit inside the bottle neck
  • Gushing
  • Haze
  • ‘Legs’
  • Foam stability/Head retention
  • Clarity
hearing
Hearing
  • Level of carbonation
  • Specific tones for specific levels of CO2
smell aroma bouquet
Smell - (Aroma/Bouquet)
  • Volatiles/Aromatics
    • Diacetyls
    • Phenolic character
    • Esters
  • Aroma from malt, grain, and fermentation
  • Bouquet directly attributable to hops
  • Odor - (Sulfur based compounds/oxidation)
taste perception
Taste Perception

Where we perceive it...

  • Bitterness* - on the back of the tongue
  • Sweetness - on the tip
  • Sourness* - on the sides of the tongue
  • Saltiness - just to rear and sides of tip

*15-20% of Americans confuse sour and bitter

taste
Taste

How beer affects the sensation of taste

  • Bitterness - Hops, Tannins, Malt, Minerals
  • Sweetness- Malt, Hops, Esters, Diacetyl
  • Sourness- Carbonation, Contamination
  • Saltiness - Minerals
touch and feel
Touch and Feel
  • Texture - creamy, over/under carbonated
  • Body - full bodied or thin...
  • Astringency - Dry, puckery feeling (Not really a flavor)
  • Others - Oily, menthol-like, burning, etc
pleasure
Pleasure
  • Overall impression
  • Close your eyes- Is it memorable?
  • Would you want another one?
maximizing flavor perception
Maximizing Flavor Perception
  • Begin with lighter styles and progress to darker, more full bodied beer
  • Don’t smoke or be in a smoky room
  • Do not eat salty or greasy food while tasting
  • Do not wear lipstick or Chapstick
  • Eat french bread or saltless crackers to cleanse palate
  • Use clean glassware

evaluating beer cont d
Evaluating Beer - cont’d
  • Taste in the mouth
    • Take a good sip
    • Swirl and slosh around your whole mouth
    • “Swizzle” (suck in air through beer in your mouth)
    • Small sip to check 4 tastes
    • Check Astringency
    • Check after-taste or tail
  • General Quality
    • Memorableness or “come hither appeal”
the taste of beer
The ‘taste’ of beer
  • Hop quality
  • Hop intensity
  • Sweet/dry balance
  • Beer character
  • Aftertaste or tail
  • Body and Palatefullness
  • Flavor balance
summary
Summary
  • Becoming a knowledgeable beer drinker takes practice
  • Taste, smell, feel, and look at your product during every step
  • Evaluate the beer as it ages
    • What sulfur characters come and go?
    • Which phenolic characters get worse with age?
    • How does bitterness and diacetyl rise and fall?
