This is the volume of spirits sold in 9-Liter equivalent cases, but does not equate to actual physical cases of beverages.
For example, if the company sold 9 bottles of 1L spirits, this would be equal to the sale of 1 case.
The 9-Liter equivalent is a standard spirits industry metric- this metric is useful to measure the volumes of spirits sold over time; the standard case size is particularly helpful when comparing sales between competitors. Apart from changing demand, price changes have serious effects on the volume of cases sold- for example, increases in case prices usually lead to declines in the volume of cases sold.
