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.
