# Entry Instructions

* Carbonation and sweetness levels are constrained in some styles; other levels are considered out-of-style. If a style lists no restrictions, then all levels are allowable.
* Perceived carbonation is dependent on judging conditions, so specifying or requiring absolute volumes of CO2 is not necessary.
* Declaring fruit varieties is allowable in any style.
* Potential allergens must always be declared.
* Vital Statistics are general guidelines, not absolutes. Commercial outliers certainly exist.
