I read this news story too.
But I think the statistics behind it are flawed because it is based on self assessment /perception.
Yes people are definitely buying more booze from the bottle shop and drinking more at home.
But I reckon overall alcohol consumption is actually down.
This is because people are not counting all the drinking they did outside of home before the lockdown; in pubs, clubs, footy, restaurants, weddings, parties, dinners, airports, functions, BBQs, picnics, casino, RSL, flights, cruises, holidays etc.
Bottle shop sales and drinking at home are up for sure, but I reckon overall drinking has decreased.
Think about all those thousands of trucks full of beer kegs, and cases of wine and spirits delivering to pubs, clubs, bars etc every day, and all of those venues full of people drinking every day and night of the week. They don't exist anymore.
