Mendip could buy beer/ wine in the meantime. But if he starts to make his own wine this weekend, in 4 weeks he'll have lots of cheap wine! (if he's impatient, he could drink it after 3 weeks, if he can bear the taste)

He could also make ginger or apple beer - it takes about 5-7 days only. But I don't know if he has the implements for that - knife, cutting board, etc. (I made ginger beer during the early days of lockdown, then I leveled up to making wine. Heh)
