|
|
Hey all -
Somewhere between my fermentor and coming out of my tap, my beers are acquiring a bit of a chemical aftertaste.
Possible issue 1:
I am cleaning my kegs with PBW, rinsing with water, and then rinsing with Starsan. I then leave a bit of starsan in the kegs for up to a couple of weeks or so before I swirl the remaining starsan and pour it out just before begging.
Possible issue 2:
I have flushed my beer lines with oxiclean and also with starsan and using a submersible pump for 10-15minutes but have never used a BLC/LLC or ALC.
I am replacing my beer lines(they are a couple of years old) and am buying some BLC at the same time.
Looking for advice. Is there something wrong with my keg cleaning/maintenance strategy?
Thanks

When you say chemical aftertaste, what sort of flavours are you talking about exactly?

I normally pour the first 1 or 2 glasses (12 oz) down the drain.

Just to be clear my comment about tossing the first glass or 2 only applies to the initial tapping of the keg. Even though I cold crash and fine, there is still settlement in the keg and especially in the first pour.

Ah! Ok. That's normal. I thought you mean whenever beer had sat in the lines. That's also normal, if you use lines that leech plastic flavour (and notice it/are bothered by it).
