Let me start with my process and then get down to the concerns later:
8 days prior to brew day, began a L. Delbruekii starter (500ml of 1.020 SG sterilized wort) and held at 92F.
Brew day: Sanitized all equipment, heated strike water and infused for saccharification @ 149F for 60 minutes. Pulled 5 quarts thick mash for mash-out decoction. Added 1 oz Hallertau hops and boiled in decoction for 15 minutes. Return decoction to main mash for mash-out. Proceed with single batch sparging, collected 5 gallons of liquid and rise to boiling temp. Cut heat at signs of beginning of boil. Chill & pitch lacto starter, added ½ lb crushed pale 2-row malt to primary to assist lacto. 24 Hours later krausen head begins to form.
~12 hours later, high krausen. With slight concern for the beer, added the originally intended US-05 yeast.
So I’m wondering now if I prepared my brew too liberally to foster conditions for spontaneous fermentation. I’m not terribly worried how the brew turns out, the whole batch probably only cost me $10. Should I have concern for any harmful pathogens?
