A "Nazarite" [either man/woman] could not partake of anything "made of the vine tree, from kernels even to the husk" while under the days of his/her "vow of a Nazarite", in his/her "separation".
Any Hebrew/Jew, not under such a vow [or some other special occurance or vow], could partake of the "wine" [unfermented, pure juice of the grape] in joyous celebrations, such as at the harvest feasts, weddings, sabbaths, etc., however, the Nazarite vow was to also even exclude even this grapejuice drink and all else that came from "the vine tree" ["wine" [unfermented or fermented], "strong drink", "vinegar of wine", "vinegar of strong drink", "liquor of grapes", "moist grapes", or "dried", etc.]:
Speak unto the children of Israel, and say unto them, When either man or woman shall separate [themselves] to vow a vow of a Nazarite, to separate [themselves] unto the LORD: Numbers 6:2
He shall separate [himself] from wine and strong drink, and shall drink no vinegar of wine, or vinegar of strong drink, neither shall he drink any liquor of grapes, nor eat moist grapes, or dried. Numbers 6:3
All the days of his separation shall he eat nothing that is made of the vine tree, from the kernels even to the husk. Numbers 6:4
It was only after the "days of his separation" "unto the LORD" were completed, and the person brought to the "door of the Tabernacle of the congregation " [Temple/church] with "a basket of unleavened bread, cakes of fine flour mingled with oil, and wafers of unleavened bread anointed with oil, and their meat offering, and their drink offerings" and then the Priest was to "take the sodden shoulder of the ram, and one unleavened cake out of the basket, and one unleavened wafer, and shall put [them] upon the hands of the Nazarite, after [the hair of] his separation is shaven".
So once the Nazarite vow was over, he/she could then go back to being able to partake of the "wine" of "joy", "rejoicing" and "blessing", the unleavened pure juice of the grape, as other Hebrew/Jews could [that were not under vows, etc]. But, as it is said, in many places of God's Holy Word [some of which has already been listed previously], the fermented "wine" of "sorrow", "woe" and "cursing" was to be avoided afterwards, even if it had not been before the vow. The whole point of the Nazarite vow was to "to separate [themselves] unto the LORD" in a special manner, and at the end to be presented before the "door of the Tabernacle of the congregation", which was the Temple/Church, with that which was unleavened, symbol of purity.
And the priest shall wave them [for] a wave offering before the LORD: this [is] holy for the priest, with the wave breast and heave shoulder: and after that the Nazarite may drink wine. Numbers 6:20
All the days of the vow of his separation there shall no razor come upon his head: until the days be fulfilled, in the which he separateth [himself] unto the LORD, he shall be holy, [and] shall let the locks of the hair of his head grow. Numbers 6:5
All the days that he separateth [himself] unto the LORD he shall come at no dead body. Numbers 6:6
He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die: because the consecration of his God [is] upon his head. Numbers 6:7
All the days of his separation he [is] holy unto the LORD. Numbers 6:8
...
And this [is] the law of the Nazarite, when the days of his separation are fulfilled: he shall be brought unto the door of the tabernacle of the congregation: Numbers 6:13
And he shall offer his offering unto the LORD, one he lamb of the first year without blemish for a burnt offering, and one ewe lamb of the first year without blemish for a sin offering, and one ram without blemish for peace offerings, Numbers 6:14
And a basket of unleavened bread, cakes of fine flour mingled with oil, and wafers of unleavened bread anointed with oil, and their meat offering, and their drink offerings. Numbers 6:15
And the priest shall bring [them] before the LORD, and shall offer his sin offering, and his burnt offering: Numbers 6:16
And he shall offer the ram [for] a sacrifice of peace offerings unto the LORD, with the basket of unleavened bread: the priest shall offer also his meat offering, and his drink offering. Numbers 6:17
And the Nazarite shall shave the head of his separation [at] the door of the tabernacle of the congregation, and shall take the hair of the head of his separation, and put [it] in the fire which [is] under the sacrifice of the peace offerings. Numbers 6:18
And the priest shall take the sodden shoulder of the ram, and one unleavened cake out of the basket, and one unleavened wafer, and shall put [them] upon the hands of the Nazarite, after [the hair of] his separation is shaven: Numbers 6:19
And the priest shall wave them [for] a wave offering before the LORD: this [is] holy for the priest, with the wave breast and heave shoulder: and after that the Nazarite may drink wine. Numbers 6:20
This [is] the law of the Nazarite who hath vowed, [and of] his offering unto the LORD for his separation, beside [that] that his hand shall get: according to the vow which he vowed, so he must do after the law of his separation. Numbers 6:21
Another example of the Nazarite vow can be found in Judges 13 - Manoah, his wife and her child, Samson. She was told that even her actions and choices were to affect the child. She was told not to eat anything "unclean" either, even as the Nazarites and any Hebrew/Jew truly following God from their heart were also not to do. We can know by the Word of God, that even after she had weened Samson, and Samson was grown, still neither were to eat of the "unclean":
But he said unto me, Behold, thou shalt conceive, and bear a son; and now drink no wine nor strong drink, neither eat any unclean [thing]: for the child shall be a Nazarite to God from the womb to the day of his death. Judges 13:7
This same principle applies to the fermented "wine". For the laws of God on this subject of the fermented "wine" have not changed:
And that ye may put difference between holy and unholy, and between unclean and clean; Leviticus 10:10.
That a Nazarite vow ended and ritual accomplished, and the scripture says, "after that the Nazarite may drink wine". "Come now, and let us reason together, saith the LORD," and ask, "Which of the two "wine" [unfermented or fermented] does God [the very God who loves us and created us and redeemed us, and the very same God of our Health and body Temples] mean is again allowable for them of His "chosen" people [Exodus 6:7; etc.], His "peculiar treasure" [Exodus 19:5; etc.] which had accomplished their Nazarite vow?"
Shall we begin to think that God actually means that they which completed their Nazarite vow could now freely partake of that fermented "wine", that "wine" of "sorrow", "woe", "contentions", "wounds", "babbling", that "biteth like a serpent", "stingeth like an adder", the "cruel venom of asps" and the "poison of dragons" [all symbols of the serpent, the devil and satan], and wherein "thine heart shall utter perverse things"?
Lest they drink, and forget the law, and pervert the judgment of any of the afflicted. Proverbs 31:5
Is "...Christ [Jesus] the minister of sin? God forbid!" [Galatians 2:17;p]
Is God Holy or no? Does He not declare that we also should be Holy?
But as he which hath called you is holy, so be ye holy in all manner of conversation; 1 Peter 1:15
Scripture is clear, God is clear:
Look not thou upon the wine when it is red, when it giveth his colour in the cup, [when] it moveth itself aright. Proverbs 23:31
When sin entered into this world, things of the natural world changed. Weeds, thorns and unconsumable things entered in, along with Death and corruption.
"Ye shall know them by their fruits. ..." Matthew 7:16;p [see also Matthew 7:20]
Either make the tree good, and his fruit good; or else make the tree corrupt, and his fruit corrupt: for the tree is known by [his] fruit. Matthew 12:13 [see also Luke 6:44]
Though the passages are speaking about people, it can also be applied to any number of things. Alcohol produces what kind of "fruit"/results in any amount? Wickedness, sloth, depravity, disease, wounds, death and sin ["...the fruit of the wicked to sin." [Proverbs 10:16;p]]. There is a reason that it is in many places called "spirits", "unclean spirits" associate themsleves with it and their worship.
