Current through Register 2024 Notice Reg. No. 28, July 12, 2024
The maturity of table grapes shall be determined by an
						examination of the grapes in a representative sample of containers taken at
						random from any lot of containers of grapes. A "lot" means any group of
						containers that contain grapes of the same variety and of the same grade or
						brand, and which is set apart or is separate from any other group or
						groups.
The following procedure shall be used to determine
						whether grapes in a lot are in compliance with the maturity standards of this
						article:
(a) Sampling method. There
					 shall be selected at random from the lot, the number of sample containers
					 specified by the following table:
100 containers less..........................
..........................3
101 to 300..........................
..........................5
301 to 500..........................
..........................6
501 to 700..........................
..........................7
For lots of over 700 containers, one additional sample
						container shall be selected for each additional 200 containers or fraction
						thereof.
(b) From the sample
					 containers selected in accordance with paragraph (a), select the three
					 containers which appear to contain the least mature grapes. From these three
					 containers, select the two that contain grapes which appear to be the least
					 mature of the three. Remove from each of these two containers 20 percent of the
					 grapes, by weight, but not less than two bunches, from a contiguous area of
					 each container which appears to be the least mature. Combine the grapes removed
					 from both containers, crush, and extract the juice for testing. After
					 extraction, agitate, thoroughly mix the juice, and test. If the test result
					 complies with the soluble solids standard specified in this article, no further
					 testing is required.
(c) If the
					 result of the soluble solids test as specified in (b) above fails to comply
					 with the soluble solids standard specified for the variety, proceed to the
					 second test as follows: thoroughly stir the juice used for the soluble solids
					 test, measure out 10 c.c. of this juice, and titrate to determine the ratio of
					 soluble solids to acid; if this ratio is equal to or higher than the ratio
					 standard of 20 to 1 and the minimum soluble solids standard as specified in
					 this article, no further testing is required.
(d) If the results of either the soluble
					 solids test provided in (b) above, or the ratio test provided in (c) above,
					 fail to equal the standard specified for the variety of grape being tested,
					 proceed to the third test as follows: remove the least mature appearing grapes
					 from the third sample container by the same procedure prescribed in (b) above,
					 extract the juice of the grapes selected from this third container, thoroughly
					 mix the juice, and proceed with the soluble solids test, determine the
					 mathematical average soluble solids percentage of the first test, (b) above,
					 and this third test (d); this percentage shall be deemed the soluble solids
					 percentage for the lot; if the result of this test complies with the soluble
					 solids standard specified in this article, no further testing is
					 required.
(e) If the results of the
					 soluble solids test provided in (d) above fail to equal the standard specified
					 in this article for the variety being tested, proceed to the fourth test as
					 follows: thoroughly stir the juice used for the soluble solids test provided in
					 (b) (the 2-box test) and (d) above (the 3-box test); remove 10 c.c. of juice
					 from each test, combine and thoroughly mix these two quantities of juice, and
					 remove 10 c.c. of this combined juice and titrate; if the result of this test
					 complies with the ratio standard of 20 to 1, and the minimum soluble solids as
					 specified in this article, no further testing is required.
(f) A second official sample may be taken and
					 tested for maturity after the immature grapes from the containers in the lot
					 failing the previous test have been removed.
