Quick Reference
Standard cooking vinegar: 5% = 50 grain
Cleaning vinegar: 6-10% = 60-100 grain
Industrial vinegar: 20-30% = 200-300 grain

Vinegar strength is measured in two ways: acidity percentage and grain.

The conversion:

  • Grain = Acidity % x 10
  • Acidity % = Grain / 10

Common vinegar strengths:

  • White distilled vinegar: 5% (50 grain) — standard cooking
  • Apple cider vinegar: 5% (50 grain)
  • Rice vinegar: 4% (40 grain)
  • Wine vinegar: 6-7% (60-70 grain)
  • Balsamic vinegar: 6% (60 grain)
  • Cleaning vinegar: 6-10% (60-100 grain)
  • Pickling vinegar: 7% (70 grain)
  • Industrial vinegar: 20-30% (200-300 grain)

Safety note:

  • Vinegar above 10% acidity can irritate skin and eyes.
  • Industrial vinegar (20%+) requires gloves and ventilation.
