The chart above shows case volume data in an index format. You can measure the current week's volume against the total average weekly volume. This index shows the weeks of the year that a segment is selling at a higher volume than its average for that year, it is also being compared to the 2017 averages. Even if a single metric may have a low overall volume share of the total industry, a share index during any given week of the year may be well above average. Every beer has a time and place to shine in the market.
