I brewed a milk stout using the recipe from 'Brewing Classic Styles' back in Nov. Its been in the bottles since a little before Christmas and started out tasting pretty good but over the last month the most recent bottles I've opened have been quite obviously sour. Does the 1lb of lactose in the milk stout make it more susceptible to infection from bacteria? I'm assuming it picked up a bug somewhere. TIA
