Bottle spread: a distribution, not one case

The standard

A recorded spread rests on several opened bottles of the same wine and states how far apart they lie. A single deviating bottle does not establish it.

Criteria

  • It rests on several bottles, not on a single case
  • It separates random deviation from a systematic flaw
  • It states the conditions under which comparison was made
  • It refers to one wine and one bottling

Distinction

Bottle spread ≠ Bottle variation: one is the distribution across many, the other the difference between two bottles. Bottle spread ≠ Bottle shock: one is a temporary state, the other a lasting distribution. A recorded spread thus separates chance from the rule.
