I'm new to the hobby and recently made my first brew, I've used a simple plastic fermenter (25L) for primary, and after I finished the bottling process I washed the fermenter and waited for a couple of weeks before washing it again thoroughly.
By the time I got around to the second wash a bad odor has developed and hasn't disappear completely when I finished washing.
The beer from the first brew turned out ok, I don't think it's the source of the odor, It mighty have been the water from the first wash, I used a hose behind my house.
Can this odor contaminate my wort if I'll use the same fermenter again? Will it affect the quality of the brew?
And if so, is there any way to get rid of it without ruining the Fermenter?
