Infected batch?

[Roliat]

My first attempt with extract. Fermentation was weird. No visual signs of fermentation, zero bubbling, zero krausen, but gravity fell every day, stopped at 1008 after 6 days. Now it smells weird and undrinkably sour. It was supposed to be irish stout, pitched at 22 C, fermented at 18-19 C. Used dry yeast which came with the can, I made starter for it. I sanitised everything, even if the kit was brand new.
What went wrong? Or is it normal and the beer will be drinkable?

I wouldn't say there are any visible signs of contamination.

Looks pretty normal to me - draw some out and taste it.

It is very sour, undrinkable right now. Any chance it will improve later?

The fuzzy white spots definitely look suspicious. Taking a SG reading every day risks contamination during the start of the fermentation when there is little protection from CO2 production and ABV is low. Being sour now it won't become less sour later. You may need to do some heavy bleaching or just replace the fermentation bucket.

What is your cleaning and sanitizing procedure.

It happens to most brewers every once in a while.

Well thanks, I was thinking the same. I used chemipro oxi, filled the ferm. bucket to 1/4 and put everything in it. Shaking mad, then let it dry.
Do you think I should dispose the whole set or try bleach it?

I had an infection a while ago. The bottling bucket is now used for collecting cucumbers and beans from the garden. Cheap to replace and also any tubing which may have touched this wort.

Chemi Pro Oxi is a good cleaner but it is not a sanitizer.

It does happen but we have all started out learning.

Instructions for a kit look odd. Ask the question. Not sure about something just ask the question. Home brewing is a life long learning experience.

Use star San to sanitize. Don’t let the bucket dry. Star San is a no rinse sanitizer. It works in a few minutes. Dump it out and put the wort in. Wait until fermentation seems to be done before you check the gravity. Use star San on anything you put in the beer to take a sample. Don’t put the sample back in. Taste it, test it, and dump it out. I would not reuse the bucket. I would skip another bucket and just get a carboy. There is not a big price difference. cheers
