Charles Ellicott Commentary Proverbs 23:30

"They that tarry long at the wine; They that go to seek out mixed wine." — Proverbs 23:30 (ASV)

They that go to seek mixed wine. —Or, To test; to see whether it is to their taste. The wines of the ancients were not generally drunk pure, but diluted with water or flavoured with spices. (See above on Proverbs 9:2.)
