First Pour From Keg Sour

[CorwinGraves]

Hello all -

I recently brewed a very popular Witbier recipe from this site and have noticed that the first pour from the tap tastes sour. If I dump the first couple of ounces then the beer tastes great.

Although I'm fine with dumping the first bit of the pour, this isn't something I've had to do before, and I've been brewing since 2007. Is this simply a case of old beer in the lines? I don't notice it with a coffee stout I have on right now. I typically only drink on the weekends, so the beer does sit for a bit between serving.

Appreciate any comments you may have.

Have you cleaned your lines recently? It's ok for beer to sit in the lines between pours, but you should run some cleaning solution through your lines periodically. Fill an empty keg with BLC and run it through your taps.

It could be a yeast taste as well. Are you getting this sour flavor with every glass you pour?

 

[CorwinGraves]

Yes, my first thought was the lines, but I recently changed them and also run BLC between kegs. It's possible that there is just something there that didn't get cleaned. Not sure.

Also, the sour taste is only with the first pour, and only really with the first couple of ounces. May have to just thoroughly clean everything before I fill this keg again.

Is it the first beer through the new line? I put new lines in my kegerator and even though they were fda approved beverage lines the first few oz had a bad taste to them, kind of chemical like, switched out the lines again and no issues.

No, it's the second beer through the new lines. Had a Belgian Blonde on first, but thinking back, it also didn't taste like it normally does. Maybe I need to replace the lines, which I'm not looking forward to, as it's a huge pain given the tap tower I have. Thanks for the suggestion, though.

Do you have a picnic tap or any way of trying a new or different line before going through the trouble of switching out your line again? Just a thought.

No, unfortunately I dont. Good suggestion.
