Quality Specifications for Grades A, B, and C

Notes:

1. This is an edited and abridged translation of the original standard which is in Spanish. Reference should be made to the original standard for details of test methods, and to authenticate any particular matter.

2. The concentrations of congeners were originally expressed solely in grams per hectolitre, but figures in parts per million (p.p.m.) have been inserted in parentheses, to facilitate comparison with specifications from other sources.
