I recently brewed a Belgian Witbier or Whitebeer, after letting it ferment I prepped to bottle it. When I opened the carboy and took a sample, the SG read around 1.012... Everything seemed to be going fairly well until I went to smell and taste the beer. Holy jesus it was sour. So I come to you was it supposed to be sour and i jus dumped it for no reason, or was I correct that somewhere along the way something was either contaminated or the airlock wasn't secure?
