Norwegian brewery pulls 'fart-smelling' beer

Norwegian brewery pulls 'fart-smelling' beer - The Local:
"A Norwegian brewery has removed all stock of one of its beers on Thursday after drinkers complained of its foul-smelling aroma.
Mack brewers, based in Tromsø, produced the “Isbjørn” (“Polar beer”), but a flaw in the manufacturing process created a drink with stomach-churning properties.
It was found that contamination in the bottling system led to a bad odour in many of the beer cans.
A build-up of lactic acid in cans led to an unpleasant smell of sulphur and rotten eggs.
The contamination was particularly rife when the weather was at its warmest this summer.
Local newspaper Harstad Tidende reported on Thursday that Mack had sold tens of thousands of cans of the "fart-smelling" drink.
In reaction to complaints, Mack has over the last few weeks tried to withdraw all “Isbjørns” produced on July 21st and 22nd this year.
...The last time Mack brewery had a similar incident was in 2013, but Karlsen assured customers incidents like this happen very rarely.
...The affected beer has an expiration date of October 22nd and 23rd."
