Hi all,
I attempted to kettle sour a Berliner Weisse. After airlock activity stopped I took a gravity ready three days in a row to confirm fermentation was finished. The first two days there were no off smells or flavours but the third day it just smells and tastes like vomit. Now I'm wondering where I went wrong.
Here's my thoughts.
1. I kettle soured in a Grainfather and was not able to purge the head space with C02. But if it got infected at this stage I'm sure I would have smelled it then.
2. I have a fermenter similar to this with a lid on top and a tap on the bottom. I figured it was safer to pull samples from the tap rather than opening the lid. But what I failed to realise was that although I had sanitiser in the airlock, it also had become a little murky from a bit of a blow out. My guess is that this may have become infected and sucked back into the fermenter when I took samples from the tap.
I'd appreciate other's thoughts on this. Also if anyone has ever kettle soured in a Grainfather, is there a good way to purge with C02?
