I brewed two IPAs a few weeks back one on the Monday and one on the Tuesday. I don't use chlorine based cleaners and use chem san for sanitising. I treated each brew exactly the same and even had the same numbers for OG and FG. The grains all come from the same bags. Hops from the same packet. Everything identical. I used two brand new grainfather fermenters and cleaned & sanitised them both identically at the same time. The fermentations where both up and running within 18 hours using the same dried yeast, sprinkled onto the wort.

One of the beers tastes great. The other is going down the drain.

I brew in my garage and use a blue food safe hosepipe for my water. The only thing I can think is the hose was left out full of water overnight between brews and it was quite warm so maybe something has come from the hose and then when I have used it the next day, I cannot remember if I started filling the brew system straight away or flushed it first. The hose is sold as food grade and has it printed along the outside of the hose.

Anyone else found TCP flavours from a food grade hose before because I cannot figure out where else it could be coming from.

Thanks

NEVER THROW A BREW AWAY!

Unless it honks of vinegar and is obviously infected!

There are many reasons why a brew may smell or taste “off” - and most of them will come good after conditioning.

I suggest that you carry on as normal and then try the brew every week for at least three months before consigning it to the drain; and only then if it doesn’t improve!

Its basically a NEIPA so I doubt ageing would help but ill give it a go!

Agreed! However:
  1. Some of my tastier brews have improved after a few weeks conditioning.
  2. The TCP taste is often associated with either a genuine infection or with excess bleach/chlorine in the water used during brewing. (The use of a Campden Tablet is recommended as a preventative measure.)
Please see what happens and let us know the result.

Perhaps it came from chlorine in the tap water left in the hose overnight?

I've had the odd brew with TCP taste and it never gets better so has to be chucked. And it is just the odd brew, one every now and again, like you from the same grain batches and just one brew is off.

Never managed to track down the cause. I've had infections before and I don't think it was that. The only thing I can think of is that the brew got a bit warm during fermentation. You say you brew in the garage, do you ferment in there too? Garages can get very hot this time of year.

Any idea if it was the first brew or second brew which has the issues . I've marked my identical FVs as FV1 and FV2 and carry it in the notes on beersmith as to which one I'm using , for ease of fault finding.
PS I've also labelled my Cornie kegs, which is logged also

I’ve got a glycol chiller and the fermentation temperatures where identical between brews.

It was the second one. I’m using the grainfather glycol chiller and grainfather fermenters so each one is assigned to a brew on the app to keep track of them.

I can only think it was the water being left in the hose out in the heat for a day must have done something.
