01 / Progress

The wine,
step by step.

  1. Source

    Oak Knoll fruit defines the style

    The Sauvignon Blanc came from the Oak Knoll District and developed the fruit-forward flavor, color, and aroma that became the cellar’s preferred white-wine direction.

  2. Cold test

    The refrigerator becomes the stabilization tank

    When bottles were held below 40°F, potassium bitartrate deposits became visible and the wine looked less brilliant than a commercial white.

    <40°F
  3. Diagnosis

    A finishing issue, not a flavor failure

    The wine continued to taste very good. The visual difference pointed to suspended material and cold instability rather than a loss of fruit or aroma.

  4. Bottle selection

    A flawed bottle obscures the wine

    The submitted bottle drew corked, oxidized, and sediment comments, so the result was not treated as representative of the vintage.

  5. Method

    Clarity becomes part of the plan

    Future whites now include bench-tested fining, tartrate control, adequate settling, careful degassing, and a final polishing filtration.

02 / Tasting record · Cellar evaluation

“The wine tasted better than it looked.”

Fruit, color, and aroma were the strengths. The opportunity was visual brilliance and cold stability—a distinction that led to a more complete white-wine finishing method.

Stability and polish
Keep in the record

Use representative bottle checks before competitions and carry the full clarity, tartrate, degassing, and filtration sequence into future whites.

03 / Notes

What stays
in the record.

The honest lesson

Cold stabilization and clarity are related, but they are not the same job. Chilling can drop tartrate crystals; it does not automatically remove protein haze, colloids, fine lees, or retained CO₂.

The method that came from it

  • Bench trial bentonite and use the lowest effective rate.
  • Allow every treatment enough time to settle.
  • Rack cleanly before final filtration.
  • Use tartrate control when the cellar cannot reach true cold-stabilization temperatures.
  • Polish at approximately 0.65 micron—or 0.45 micron when the wine and equipment allow.
  • Hand-select and test representative competition bottles.
