Hi guys,
Just went to bottle my porter, and I think I have an infection. My last 5 beers have been (most recent first):
- Porter (infected I think)
- Blonde (slightly sour smelling but tastes fine after 2 weeks in bottle)
- Pale (tasted sour, dumped)
- NZPA (sour, dumped)
- NZPA (bottled, but sour and cloudy)
This is what I've just seen in my primary, after about 7 days. I occasionally taste off the primary (through a tap) and it's only just taken this turn for the worse - late in the ferment.
My cleaning and sterilising is always good. From the kettle my wort runs through a tube and a sieve which are both cleaned vigorously before transfer to the FV, and my FV always gets proper attention too. I use Star San IO.
My question is, what could I be missing?
My theories are:
- I use loose lid fermentation on my FV, but leave the lid on properly, just not click down fully
- I top up with tap water after boil, but have never had this problem before
- could be some grime inside the butt tap on the FV? Should I get a pipe cleaner and scrub it out?
It's the same taste every time, and always has this oily surface on top. So I'm sure it's from the same source. Obviously has to be post boil (unless I'm mistaken).
Any advice would be more than welcome! Feel free to ask about anything I might have forgotten to explain.
