Hi this is my first phost here. Be gentle I made a beer from a receipt I found at my local brew shop with belle saison and it turned out awsome. Now I wanted to exbeeriment with it. I made one with pilsner malt exclusively, brew in bag with 65C (149F). It has been in the botles now for abut 3weeks i have been sampling it on ocation. 2 days ago it tasted good with some yest funk. To day no yeast funk but realy sour. 2 days ago it tastes sweater than it did before (it tasted green) .I had to taste 2 bottles to day to make certain that it wasn't just that one bottle that had an infection. Does any body have a good idea of what is going on? Its not horrible tasting and Ihave tasted sours that where more sour but its border line on beeing an all out sour.
