Ok, the background information. 2 weeks ago I brewed a sweet stout. It was based off Gordon Strong's recipe and I've done it before with great results. Pretty standard brew day- I did cold steep the dark grains. I had a 1 1/2 liter stirplate starter (002) built. Now I had previously planned to brew the weekend before so that starter had been sitting in the fridge for about a week. I brewed as usual and pitched the yeast. Checked on it the next day- no signs of fermentation. I waited another day- no signs of fermentation. I pitched my yeast bank (I always oversize my starters by 1/2 liter and save it in a pint jar) 002 on the third day. Slow signs of fermentation ensued so I left it alone for 1 1/2 weeks. Took a gravity sample yesterday before racking as I was concerned about an incomplete fermentation. 1.022 and a strong taste of acetic acid.
So I'll dump the batch but I want to make sure that nothing survives in that glass carboy. The plan is to clean the carboy as usual and then fill it with chlorine bleach solution for a day, clean it again, and sanitize as usual (StarSan or SaniClean). Will this be sufficient?
Thanks in advance
