Has anyone ever used well water while making beer? Reason I'm asking is because my first batch of beer ever brewed did not turn out good. I used a Midwest supplies American light 20 minute boil kit. I followed the directions and made sure everything was cleaned with oxy clean and sanitized with starsan. I used dry yeast a plastic bucket for primary and a better bottle for secondary. I described the taste as plastic and had two others try it and they described it as sour. I've been brewing wine for awhile and used well water with them but haven't had any off flavors. My temperature stayed around the mid to upper 60's except for one day I left the heater on too high and the temp got up to 77 while in the secondary but only for a day. Does anyone have any ideas of what could've happened?
