olives-like flavour

[jagg1]

I have found some strong notes of olives in a couple of homebrews and was wondering where do those come from. Also what it is. My guess is those should never be in a beer??
Thx!

Green, Black, or Blue Cheese Stuffed Olives?

sorry i couldn't resist>:)

oxidized fatty acids? (rancid)

there's little typical homebrewers can do against oxidation.

Try the homebrew digest www.hbd.org

I am not the brewer. I have have tried some homebrews in my area and this strong olive-like flavour/odour tends to be in like 70 % of them, making those beers very unpleasent to drink. Not to say all the phenolic compounds I have been able to detect. Just do not know where do this particular flavour comes from.
Thx!!!

are all the beers from the same homebrewer

[jagg1]

different homebrewers.

My guess would be it's Brett. I've tasted alot of Lambics with olive-like flavors.

[liammckenna]

I agree with Scott. I've also encountered it in Flemish brown ales.

Pax.
