27 CFR § 24.291 - Removal of wine for vinegar production.
(a) General. Still wine or still hard cider may be removed from bonded wine premises, without payment of tax, for use in the manufacture of vinegar. Where the proprietor is also the proprietor of a vinegar plant located adjacent or contiguous to the bonded wine premises, wine may be removed without payment of tax upon filing a consent of surety extending the terms of the wine bond to cover the removal and use of wine in the manufacture of vinegar. Where the proprietor of a vinegar plant is not the proprietor of an adjacent or contiguous bonded wine premises, the proprietor of the vinegar plant may receive wine, without payment of tax, for use in the manufacture of vinegar by filing a bond under the provisions of § 24.146(c) to cover the removal to and use of wine at the vinegar plant.
(b) Vinegar plant records. Each proprietor of a vinegar plant to which wine is shipped, without payment of tax, for use in the manufacture of vinegar shall keep a record of all wine received and used for the manufacture of vinegar and of all vinegar produced and disposed of. The record will show the following information:
(1) The volume and alcohol content of all wine received, the date of receipt, and the name, registry number, and address of the bonded wine premises from which received;
(2) The volume and alcohol content of all wine used in the manufacture of vinegar, and the date of use;
(3) The volume and grain strength of the vinegar produced, and the date of production. (This volume will be reported on a 100-grain strength basis and will be determined by multiplying the wine gallons of vinegar produced by the grain strength thereof and dividing the result by 100); and
(4) The names and addresses of all persons to whom vinegar is shipped, the volume and grain strength shipped to each, and the date of shipment. (Grain strength is a measure of the acetic acid content of vinegar, expressed as 10 times the grams of acetic acid per 100 mL).
(c) Inspection of vinegar plants. The proprietor of a vinegar plant receiving wine, without payment of tax, for use in the manufacture of vinegar shall make the premises and records available for inspection by appropriate TTB officers during regular business hours.
