The beer maker will also serve beer within the ticketed perimeter surrounding each stadium, where the beer price is "to be confirmed," said the source, who declined to be named.
"We recognise there is an issue with price," Qatar 2022 Chief Executive Nasser Al Khater said in 2019.
At the FIFA Club World Cup held in Qatar that year a half-litre of beer cost around $6.50.
Qatar's World Cup organisers, the Supreme Committee for Delivery & Legacy, would not confirm the price of beer served inside the fan zone when contacted on Tuesday.
"Pouring times and number of pouring destinations remains the same across all eight World Cup stadiums," the spokesperson said in a statement.
