My latest batch of ipa has a distinct solvent like aroma and taste like anticeptic/tcp. Does anyone have any input as to what could have caused this? Is over-hopping a possibility? Here’s my hop schedule:

2oz Chinook 60 mins

2oz simcoe 5mins
2oz Amarillo 5mins
2oz Nelson sauvin 5 mins

2oz simcoe flameout
2oz Amarillo flameout
2oz nelson sauvin flameout

2oz nelson dry hop 5 days
4oz simcoe dry hop 5 days

It’s quite a lot of hops but I struggle to believe that this solvent like aroma has come from the hops, it’s quite unhop-like. The beer doesn’t appear to be showing any signs of infection. I sanitize with VWP alkaline solution, pretty sure I rinsed well but maybe this could be it, although the flaw doesn’t taste like the vwp, the vwp has more of a chlorine aroma

what yeast, what did you ferment at, what water are you using?

First of all: how many liters/gallons is the batch??

White labs Californian ale liquid yeast. Fermented at 20C (68F). Scottish water straight out the tap, no treatment. 20L batch

More than half a kg of hop in a 20l batch, i think this is too much, even for a IPA. Non treated water may affect also. Try asking for a detailed water analysis from your water provider and see its mineral contents.

The solvent character is definitely not the result of over-hopping. Our IPA is pretty close to this amount of hops and our DIPA is about 50% more.

As far as the actual source of the problem, I would be looking at your knock-out/pitching/O2 procedures as well as the activity during the lag phase. Did you make a starter?

Hmmm, I bottled a couple of clear bottles of this, I usually do so I can see how the beer’s looking.It seems to be going hazy and there’s residue sticking to the inside of the bottle. I’m thinking it may have some kind of infection afterall. It’s not sour though, no vinegar, not minerally, could just have something weird in it. I think it’s a drain pour either way, tastes pretty bad.

It could be chlorphenols from the chlorine/chloramines in the water or from the sanitizer. When they mix with phenols from the rest of the ingredients they form a really off medicinal character that we are fantastically sensitive too.



I don’t think 20 oz of hops is the problem, although I’m amazed you can smell anything over them!

Is this beer done and bottled? How old is it? I got the same kind of super harsh flavors out of my recent IPA after ten days. It’s been 16 now and it has gotten a lot better. I transfered, a lot of the particle matter in suspension was left behind/dropped out of it right after transfer, it cleared up very nicely.

Proof that you can’t just cover most flaws with more hops.
