Handling Considerations

Handling Considerations Vinegar is generally shipped in varying grain strengths in 30 to 55 gallon containers, or in tanker trailers. Shipping vinegar in concentrated form provides an advantage in reduced freight costs and storage space requirements, without affecting quality. The amount of concentration of the vinegar is indicated by the grain strength, or grainage. In the U.S., the grain strength is calculated as 10 times the acid content expressed as acetic acid (i.e. 60 grain vinegar = 6% acetic acid and 120 grain = 12% acetic acid). Concentrated vinegars can then be diluted' to desired strength during processing.

Bulk vinegar products in general are not pasteurized but have been filtered to remove extraneous particles. Manufacturers should take precautions not to expose vinegar to air. Cloudiness may result or formation of Mother.

Vinegar containing Mother is not harmful. If vinegar Mother is apparent, the substance can be removed by filtering and the organisms destroyed by heating or sterilization.

All vinegars, if properly handled, are very stable with respect to quality. The shelf life of vinegar can vary somewhat due to the type of vinegar, container, packing method, storage and transportation. White distilled vinegars, if not otherwise contaminated, will remain virtually unchanged for an almost indefinite period. Changes may be observed over time in other vinegars, particularly with respect to color and clarity. However, the only effect is an aesthetic one, and the product can still be used with confidence.
