Yes after death, repentance is no longer accepted. But the three events I meant are of the major signs :
It is narrated on the authority of Abu Huraira that the Messenger of Allah (ﷺ) observed:
When three things appear faith will not benefit one who has not previously believed or has derived no good from his faith: the rising of the sun in its place of setting, the Dajjal, and the beast of the earth. (Sahih Muslim)

Certainly Allah has the final say, but the chance of repentance is always there, until death or until three events (whichever happens first)
Narrated Abu Hurairah:
that the Messenger of Allah (ﷺ) said: "The adulterer is not a believer while he is committing adultery, and the thief is not a believer while he is stealing, but there is a chance for repentance; (if he repents, Allah will accept the repentance)." Jami'at-Tirmidhi
Abu Huraira reported Allah's Messenger (ﷺ) as saying:
Allah is more pleased with the repentance of His servant when he turns penitently towards Him than one of you would be on finding the lost camel. (Sahih Muslim)
Narrated Anas bin Malik:
Allah's Messenger (ﷺ) said, "If Adam's son had a valley full of gold, he would like to have two valleys, for nothing fills his mouth except dust. And Allah forgives him who repents to Him." (Sahih al Bukhari)
[FONT="]Abu Musa reported Allah's Messenger (ﷺ) as saying that Allah, the Exalted and Glorious, Stretches out His Hand during the night so that the people may repent for the fault committed from dawn till dusk and He stretches out His Hand during the day so that the people may repent for the fault committed from dusk to dawn. (He would accept repentance) before the sun rises in the west (before the Day of Resurrection). A hadith like this has been narrated on the authority of Shu'ba with the same chain of transmitters. (Sahih Muslim)[/FONT]
[FONT="]It is narrated on the authority of Abu Huraira:

[FONT="]A fornicator who fornicates is not a believer as long as he commits fornication, and no one who steals is a believer as long as he commits theft, and no one who drinks wine is a believer as long as he drinks it, and repentance may be accepted after that. (Sahih Muslim)[/FONT]

As for drinking alcohol (OP's question)
It was narrated from ‘Abdullah bin ‘Amr that the Messenger of Allah (ﷺ) said:
“Whoever drinks wine and gets drunk, his prayer will not be accepted for forty days, and if he dies he will enter Hell, but if he repents, Allah will accept his repentance. If he drinks wine again and gets drunk, his prayer will not be accepted for forty days, and if he dies he will enter Hell, but if he repents, Allah will accept his repentance. If he drinks wine again and gets drunk, his prayer will not be accepted for forty days, and if he dies he will enter Hell, but if he repents Allah will accept his repentance. But if he does it again, then Allah will most certainly make him drink of the mire of the puss or sweat on the Day of Resurrection.” They said: “O Messenger of Allah, what is the mire of the pus or sweat? He said: “The drippings of the people of Hell.” (Sunan Ibn Majah, Jami'at-Tirmidhi)
