How should RTD volume be calculated and reported as case equivalents when the ABV differs significantly from standard spirits?

RTD reporting requires a conversion methodology to compare volumes against standard spirit case equivalents. Members use two practical approaches: - **Diageo's 10x volume method** — treats RTD volume as 1/10th of a standard case equivalent by ABV ratio (90L of RTD ≈ 1 × 9L case equivalent), based on the logic that spirits are ~40% ABV and RTDs are approximately 1/10th of that. - **Spirit content method** — calculate the actual spirit volume required to produce the RTD batch, then use that as the case equivalent. For example, a 20L KeyKeg of spritz requiring 5L of base spirit would be reported as 5L case equivalent. Members note this is "probably not the 'right' way" by industry standard but works logically for internal tracking and is easy to apply consistently.
