color change after bottling
 
I brewed a belgian blonde ale that fermented out to about 1.012 with sacc. I then added Brett B, (from Orval dregs, Wyeast Brett B, and WY Trappist blend) which took it down to 1.000 pretty quickly. At bottling, the beer tasted great. It was pale in color and had a nice subtle Brett flavor. I primed it with carb tabs and cracked one open three weeks after bottling. The result was very disappointing. The beer was purple colored and completely undrinkable.

Has anyone had this happen before and what do you think happened? I have opened and dumped every bottle and they were all the same. I am guessing that it picked up something from the bottling bucket (Better Bottle with spigot) or from the carb tabs (opened packs kept in a mason jar).

Thanks,
Tom

Purple!

Some of my sours taste a bit off for a few months after bottling, and sometimes they get a bit hazy which makes them look a bit darker, but unless you had some weird sort of sanitizer in there I have no idea.

Got a picture?

Here's a picture from my phone. Before bottling it was around 3 or 4 srm. I use star san to sanitize but I didn't think that it would affect color like iodophor might if used at a high dose. The flavor change is even more drastic than the color change though.

I had the exact same issue.

It's actually happened to me twice. First time was a batch of no-boil Berliner Weisse. I split the batch with my buddy. His was perfectly fine. Mine turned into this ruddy purplish mess. Tasted gnarly metallic and papery. When I dumped the keg, there was a pool of purple sludge at the bottle of the keg.

Fast forward a year later and we pull 20 gallons out of our sour barrel, split into 4 carboys. 3 out of the 4 carboys are tainted with this purple gnar. We are quite desparate to figure this one out so that we don't spoil any more beer that we've been aging for over a year.

The keg/carboys in question were cleaned with oxyclean and sanitized with star-san.

I had the exact same thing happen to me. All brett brux trois primary, pale meets IPA, warrior bitter, nelson sauvin and motueka late hops, nelson sauvin motueka and citra dry hop.

This is a sample poured after I took the FG reading:

...and this is from after I opened a bottle 6 days later (fully carb'd BTW):

I'm going to let it sit in bottles for a few more weeks

I've had the same experience on a Saison with Brett B that I made. It transitioned from a very light colored beer (simple pils and wheat grist) to a dark purple(y) color. I don't have a pic on my iPad, but I tweeted a photo of the beer after it had darkened:

I've looked around for some reference on the subject and haven't found much.

This is probably the most interesting thread I have seen on HBT.

This conversation is happening on Babble Belt as well:

Very odd...
