Serving Size

II.3 How Does the Rule Define Single-Serving Container?

A single-serving container is a product that is packaged and sold individually and contains less than 200 percent of the applicable reference amount for that product (21 CFR 101.9(b)(6)). The entire content of a single-serving container must be labeled as one serving (21 CFR 101.9(b)(6)). Under the final rule, regardless of the size of the RACC, all products that are packaged and sold individually and contain less than 200 percent of the applicable reference amount for that product must be labeled as a singleserving container (21 CFR 101.9(b)(6)). However, if the product is more than 150 percent and less than 200 percent of the applicable RACC, the manufacturer may voluntarily provide an additional on the Nutrition Facts label, to the left of the column that provides nutrition information per container (i.e., per serving). The voluntary column would list the quantitative amounts and the percent Daily Value (DV) per common household measure that most closely approximates the RACC (21 CFR 101.9(b)(6)).

Basically you will need to decide the serving size of your Kombucha. So if you currently sell at 16oz size, that would need to be considered a single serving and the full amount of calories, sugar grams etc would need to be listed for that size. If your serving size is 10oz and you sell a 16oz bottle, the container will need the info for 10oz product and may voluntarily include nutrition info per container (meaning for the full amt in the bottle).

We’ve seen many brands change from 16oz to a smaller serving size (10-14oz)
