The net contents of wine for which a standard of fill is prescribed in § 4.72 shall be stated in the same manner and form as set forth in the standard of fill. The net content of wine for which no standard of fill is prescribed in § 4.72 shall be stated in the metric system of measure as follows:\n(1) If more than one liter, net contents shall be stated in liters and in decimal portions of a liter accurate to the nearest one-hundredth of a liter.\n(2) If less than one liter, net contents shall be stated in milliliters (ml).\n(b) Statement of U.S. equivalent net contents. When net contents of wine are stated in metric measure, the equivalent volume in U.S. measure may also be shown. If shown, the U.S. equivalent volume will be shown as follows:\n(1) For the metric standards of fill shown in table 1 to paragraph (b)(1), the equivalent U.S. measures are:\nTable 1 to Paragraph (b)(1)\nMetric measure Equivalent U.S. measure\n3 liters (L) 101 fluid ounces (fl. oz.).\n2.25 L 76.1 fl. oz.\n1.8 L 60.9 fl. oz.\n1.5 L 50.7 fl. oz.\n1 L 33.8 fl. oz.\n750 milliliters (mL) 25.4 fl. oz.\n720 mL 24.3 fl. oz.\n700 mL 23.7 fl. oz.\n620 mL 21.0 fl. oz.\n600 mL 20.3 fl. oz.\n568 mL 19.2 fl. oz.\n550 mL 18.6 fl. oz.\n500 mL 16.9 fl. oz.\n473 mL 16 fl. oz.\n375 mL 12.7 fl. oz.\n360 mL 12.2 fl. oz.\n355 mL 12.0 fl. oz.\n330 mL 11.2 fl. oz.\n300 mL 10.1 fl. oz.\n250 mL 8.5 fl. oz.\n200 mL 6.8 fl. oz.\n187 mL 6.3 fl. oz.\n180 mL 6.1 fl. oz.\n100 mL 3.4 fl. oz.\n50 mL 1.7 fl. oz.\n(2) Equivalent volumes of less than 100 fluid ounces will be stated in fluid ounces only, accurate to the nearest one-tenth of a fluid ounce; for example, 700 ml (23.7 fl. oz.).\n(3) Equivalent volumes of 100 fluid ounces or more will be stated in fluid ounces only, accurate to the nearest whole fluid ounce; for example, 6 liters (203 fl. oz.).\n(c) Net contents marked in bottle. The net contents need not be stated on any label if the net contents are displayed by having the same blown, etched, sand-blasted, marked by underglaze coloring, or otherwise permanently marked by any method approved by the appropriate TTB officer, in the sides, front, or back of the bottle, in letters and figures in such manner as to be plainly legible under ordinary circumstances, and such statement is not obscured in any manner in whole or in part.\n(d) Tolerances. Statement of net contents shall indicate exactly the volume of wine within the container, except that the following tolerances shall be allowed:\n(1) Discrepancies due exclusively to errors in measuring which occur in filling conducted in compliance with good commercial practice.\n(2) Discrepancies due exclusively to differences in the capacity of containers, resulting solely from unavoidable difficulties in manufacturing such containers so as to be of uniform capacity: Provided, That no greater tolerance shall be allowed in case of containers which, because of their design, cannot be made of approximately uniform capacity than is allowed in case of containers which can be manufactured so as to be of approximately uniform capacity.\n(3) Discrepancies in measure due to differences in atmospheric conditions in various places and which unavoidably result from the ordinary and customary exposure of alcoholic beverages in containers to evaporation. The reasonableness to discrepancies under this paragraph shall be determined on the facts in each case.\n(e) Unreasonable shortages. Unreasonable shortages in certain of the containers in any shipment shall not be compensated by overages in other containers in the same shipment.","path":["Title 27—Alcohol, Tobacco Products and Firearms","CHAPTER I—ALCOHOL AND TOBACCO TAX AND TRADE BUREAU, DEPARTMENT OF THE TREASURY","SUBCHAPTER A—ALCOHOL","PART 4—LABELING AND ADVERTISING OF WINE","Subpart D—Labeling Requirements for Wine"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-27.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:25:11Z","sha256":"0e45d2db49de35d6d5853ee701c484dec3990f357df872a32c5016c2c05a411b","source_id":"us-cfr","stale":true,"prev":"us/27-cfr-4.36","next":"us/27-cfr-4.38"},"notice":"GroundRules: Original legal text.
