What “unfiltered” means

A deeper guide to what “unfiltered” means, trade-offs, return to krug, evidence ladder, after-class fieldwork, synthesis, transfer.

The argument

What this chapter will give you

This chapter supports the lesson’s central job: follow Krug’s component library into blending decisions, then distinguish settling, racking, fining and filtration from stability and quality.

This is a reading chapter, not a definition enlarged to fill a screen. Its sections build the idea from mechanism and method to the language you can use in front of an actual glass.

01

What “unfiltered” means

Unfiltered says one technique was omitted or limited. It does not prove the wine was untouched, cloudy, unstable, superior, or alive in a mystical sense. Settling, racking, fining, sulfur, and careful bottling may still be involved.

02

Trade-offs

Every finishing action has a target, a dose, a benefit, and a possible cost. The correct question is not “Was anything done?” It is “What risk was addressed, and what evidence justified the action?”

03

Return to Krug

Julie Cavil’s committee shows why blending deserves respect as authorship. Hundreds of preserved choices become one coherent wine through memory, measurement, disagreement, and judgment.

04

Evidence ladder

Producer facts establish scale and methods. Enology explains stability targets. Sensory tasting evaluates the result. A clear bottle cannot tell you which operations occurred unless the winery documents them.

05

After-class fieldwork

After class, create three measured blends from two beverages at ninety-ten, seventy-thirty, and fifty-fifty. Compare balance and finish. Keep the liquids food-safe and treat the exercise as proportion training only.

06

Synthesis

Ask what components existed, why they stayed distinct, who judged them, what the target composition was, which instability risks remained, and how each finishing action addressed a named risk.

07

Transfer

The wine is composed and stable enough to travel. Next the closure becomes part of its future, controlling an imperfect exchange among oxygen, consistency, ageing, and the person who eventually opens the bottle.

Bring it back to the glass

Three checks before the conclusion

  1. Record the sensory observation before proposing a grape, place, climate, or production cause.
  2. Compare intensity, timing, location, and persistence instead of relying on a single descriptor.
  3. State a plausible alternative and lower confidence when one clue is doing all the work.

The language bench

Solid things you can actually say

Use these as sentence shapes, not answers to copy. Replace the details with what your glass can defend.

Smell

What is actually aromatic?

  • “The aroma is moderately intense and led by a broad fruit family.”
  • “A second savoury note becomes clearer as the sample warms.”
  • “I am confident about the family, but not a precise descriptor.”
Taste

Which basic qualities are present?

  • “The wine is dry, with noticeable sourness and little obvious bitterness.”
  • “Fruit flavour fades before the structural sensations.”
  • “Sweetness is present but balanced by acidity.”
Feel

What happens through time?

  • “The palate feels medium-bodied and gently coating.”
  • “A fine drying texture develops along the gums.”
  • “Warmth appears late and persists in the throat.”
Overall

What does the pattern support?

  • “Several observations support this interpretation, but the glass does not prove it.”
  • “The strongest evidence is structural; the origin remains uncertain.”
  • “The line worth keeping is: Clear, stable and good are three different claims.”

Make the sentence earn its keep

Too loose

“It is fruity and smooth.”

More useful

“It has moderate fresh-fruit aroma, medium acidity, and a soft, low-grip texture.”

The stronger sentence identifies sensory channels and observable relationships.

A five-minute field exercise

  1. Write one smell, taste, and texture sentence.
  2. Add the likely explanation on a separate line.
  3. Give the explanation a confidence level and name one alternative.
The line worth keeping

Clear, stable and good are three different claims.
