I brewed a lemondrop sour on Christmas ( the wife got me a 10 gl gas one brew kettle had to try it out right?) As i was brewing i thought hell why not add some peaches to this. First was the nightmare of pitching my yeast (Philly Sour) and it didnt take off within 24 hrs. Yesterday i finally saw some action kinda excited about that. i already had some fresh peaches in the freezer from grandmas peach cobbler over the holiday. So my question is when is a good time for me to add the peaches and if so should i puree them. Also should i go ahead and add a campden tablet to them now while they are thawing out even though this is a sour and i know there is bacteria involved in the fermenting process?
