“Wine” From Boyd’s Bible Dictionary:

(drink). The Hebrews manufactured and used wine from earliest times (Gen. 9:20-21; 19:32; 27:25; 49:12; Job 1:18; Prov. 23:30-31; Isa. 5:11). A usual drink-offering at the daily sacrifices (Ex. 29:40); at the presentation of first fruits (Lev. 23:13); and at other offerings (Num. 15:5). It was tithable (Deut. 18:4). Nazarites could not drink it during their vow (Num. 6:3), nor priests before service (Lev. 10:9).

“Lees” From Concise Bible Dictionary:

Apple Wine Lees
“Wines on the lees” are wines left undisturbed on their sediment to mature (Isa. 25:6). The expression “settled on the lees” is used figuratively of Moab, which had not been disturbed as other nations (Jer. 48:11). Also for those who in Jerusalem remained in the Jordan valley indifferent and undisturbed amidst the evils upon which punishments were threatened (Zeph. 1:12). A very significant type of the poor apathetic world, and of the self-satisfied and unconcerned spirit of Christendom.
Stirred and unstirred barrels of Chardonay.

“Wine” From Concise Bible Dictionary:

There are several Hebrew words translated wine, and though various expressions are attached to it as “sweet,” “new,” “strong,” “good,” “mixed,” “spiced,” “on the lees,” all are wine; and the wine was intoxicating, as seen already in the days of Noah (Gen. 9:21). Intemperance is the abuse of it, and against such abuse there are abundant protests and warnings in the scripture. Wine is mentioned with corn and oil, among the good gifts wherewith God would bless His earthly people (Deut. 7:13; Psa. 104:15). It was daily offered in the temple as a drink offering (Num. 28:7).
Wine was created by the Lord in His first recorded miracle (John 2:3-10). He was blasphemously spoken of as a wine-bibber; and He said at the last Passover, “I will drink no more of the fruit of the vine, until that day that I drink it new in the kingdom of God” (Mark 14:25). He also instituted the Lord’s Supper with the cup of wine. Paul recommended Timothy to take a little wine for his frequent sickness; and a bishop must not be given to much wine. There is therefore adequate evidence that wine is regarded as a beneficent gift of God, of which man may make a moderate use. If, however, a man has no power over his appetite, doubtless he had better abstain from wine altogether. Drunkards shall not inherit the kingdom of God (1 Cor. 6:10).
