So I brewed a porter a few months ago and cracked open a 500 ml bottled last night.
To my surprise, I lost most of it in the sink since it kept foaming out of the bottle. My friend, who brewed with me, had the same thing happen to him with one of his bottle and he told me it had a sour taste, so it was definitely infected.
This makes me believe my bottle was also infected, but from the small sample I've got to drink out of it, it wasn't sour at all. It tasted like a normal porter.
Can infection occur without leaving any taste?
The bottles have been kept at room temp ever since the bottling, not sure if it's relevant or not. Also, the bung fell in the carboy right before fermentation. It was sanitized so it shouldn't have infected the batch. I put a sanitized foil paper over the carboy's neck to prevent infection.
I took a few look at the carboy during the fermentation to make sure the batch wasn't infected and it did look clean. No sign of infections at all.
So yeah, if it isn't infection, what can cause my bottle of porter to overfoam and leave no undesired taste behind?
Thank you.
