My opinion is that you fix it as the mildest punishment. Then 'Umar inflicted eighty stripes.  

أَنَّ نَبِيَّ اللَّهِ ﷺ جَلَدَ فِي الْخَمْرِ بِالْجَرِيدِ وَالنِّعَالِ ثُمَّ جَلَدَ أَبُو بَكْرٍ أَرْبَعِينَ فَلَمَّا كَانَ عُمَرُ وَدَنَا النَّاسُ مِنَ الرِّيفِ وَالْقُرَى قَالَ مَا تَرَوْنَ فِي جَلْدِ الْخَمْرِ فَقَالَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ أَرَى أَنْ تَجْعَلَهَا كَأَخَفِّ الْحُدُودِ قَالَ فَجَلَدَ عُمَرُ ثَمَانِينَ  

The Prophet ﷺ gave a beating with palm-branches and sandals for drinking wine and Abu Bakr gave lashes. When ‘Umar came to power, he called upon people and said to them: The people are living now near watering placing, and, according to Musaddad’s version, “near villages and watering places, so what do you say about the punishment for (drinking) wine? ‘Abd al-Rahman b. ‘Awf said: We think that you should prescribe the lightest punishment. So he fixed eight lashes for it. Abu Dawud said: It has also been transmitted by Ibn Al 'Arubah from Qatadah from the Prophet ﷺ to the effect that he gave a beating forty times with palm branches and sandals. And Shu'bah narrated it from Qatadah on the authority of Anas from Prophet ﷺ. This version has: He gave a beating with two palm-branches about forty times.  

أَنَّ النَّبِيَّ ﷺ جَلَدَ فِي الْخَمْرِ بِالْجَرِيدِ وَالنِّعَالِ وَجَلَدَ أَبُو بَكْرٍ ؓ أَرْبَعِينَ فَلَمَّا وَلِيَ عُمَرُ دَعَا النَّاسَ فَقَالَ لَهُمْ إِنَّ النَّاسَ قَدْ دَنَوْا مِنَ الرِّيفِ وَقَالَ مُسَدَّدٌ مِنَ الْقُرَى وَالرِّيفِ فَمَا تَرَوْنَ فِي حَدِّ الْخَمْرِ فَقَالَ لَهُ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ نَرَى أَنْ تَجْعَلَهُ كَأَخَفِّ الْحُدُودِ فَجَلَدَ فِيهِ ثَمَانِينَ  

[Machine] The prophet ﷺ was flogged with leaves and sandals in the issue of alcohol, and Abu Bakr was also flogged. Yahya said in his narration: forty times. When Umar approached the people from the countryside and villages, he asked his companions, "What do you see?" Abdur-Rahman replied, "Make it the lightest of punishments." Then Umar flogged eighty times.  

جَلَدَ النَّبِيُّ ﷺ فِي الْخَمْرِ بِالْجَرِيدِ وَالنِّعَالِ وَجَلَدَ أَبُو بَكْرٍ قَالَ يَحْيَى فِي حَدِيثِهِ أَرْبَعِينَ فَلَمَّا كَانَ عُمَرُ وَدَنَا النَّاسُ مِنَ الرِّيفِ وَالْقُرَى قَالَ لِأَصْحَابِهِ مَا تَرَوْنَ؟ فَقَالَ عَبْدُ الرَّحْمَنِ اجْعَلْهَا كَأَخَفِّ الْحُدُودِ فَجَلَدَ عُمَرُ ثَمَانِينَ  

[Machine] "That the Messenger of Allah ﷺ and Abu Bakr were lashed for alcohol with a whip and sandals. When Umar ibn al-Khattab became the caliph, people from the countryside and villages approached him. Umar consulted the people regarding the punishment for alcohol. Abdul Rahman ibn Awf said, 'O Amir al-Mu'minin (Commander of the Believers), whenever someone drinks it, they should be expelled. And whenever someone is expelled, they should be stoned. So we suggest that you make it the lightest of punishments.' The first person to be lashed for alcohol was Umar bin Khattab, may Allah be pleased with him, and there were eighty others after him."  

«أَنَّ رَسُولَ اللَّهِ ﷺ وَأَبَا بَكْرٍ جَلَدَا فِي الْخَمْرِ بِالْجَرِيدِ وَالنِّعَالِ» فَلَمَّا قَامَ عُمَرُ بْنُ الْخَطَّابِ دَنَا النَّاسُ مِنَ الرِّيفِ وَالْقُرَى فَاسْتَشَارَ عُمَرُ النَّاسَ فِي جَلْدِ الْخَمْرِ فَقَالَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ «يَا أَمِيرَ الْمُؤْمِنِينَ مَتَى مَا يَشْرَبْهَا يُهَجَّرْ وَمَتَى مَا يُهَجَّرْ يُقْذَفْ فَنَرَى أَنْ تَجْعَلَهُ كَأَخَفِّ الْحُدُودِ» فَكَانَ أَوَّلُ مَنْ جَلَدَ فِي الْخَمْرِ ثَمَانِينَ عُمَرُ رِضْوَانُ اللَّهِ عَلَيْهِ  

" عَنْ أنس أَنَّ النَّبى ﷺ جَلَدَ فِى الْخَمْرِ بِالْجَرِيدِ وَالنِّعَالِ، ثُمَّ جَلَد أَبُو بَكْرٍ أَرْبَعِين، فَلَمَّا كَانَ عُمَرُ وَدَنَا النَّاسُ مِنَ الرِّيفِ وَالْقُرَى، قَالَ: مَا تَرَوْنَ فِى حَدِّ الْخَمْرِ؟ فَقَالَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ: أَرَى أَنْ تَجْعَلَها كَأَخَفِّ الْحُدُودِ، فَجَعَلهَا عُمَرُ ثَمَانِينَ ".
