pilsner ipa turned brownish, please help.

[ldtagtrip]

Hello there,

I brewed an awesome ipa with 80% pilsner and 20% maris otter, i boiled for 90 min, usual for pilsner, and i used a full pound of hops in multiple aditions.
beer turned out great with a very nice tropical flavor and aroma, nice round mouthfeel. unfortunetly, after after a few weeks, the color went from golden to brownish and when it goes in the fridge i get a chill haze also.
the flavor hasnt changed much after the color changed but it tastes somehow more YEasTy. i botle condition all my beers.
yeast used wyeast 1056/
according to my research, i tryed to identify the issues;

Didn't perform a protein rest at 131.
one step sanitizer left in the botle.
Didnt oxygenate my wort.
high sparge temperature.
added more of the same yeast used in the fermentation to carbonate without washing my yeast.
reaction from the botle cap with one step sanitizer.

Please help me on this one, it is killing me the fact that the beer looks very dark.
please see the photo below.
funny fact, i opened a hefeweizzen style botle of the same beer with plastic lid attached to it and it was nice and golden.

the one on the was in the fridge and the one on the right at room temp.

Someone with more knowledge than me might come along, but doesn't oxidation or staling sometimes change the color? The yeasty bit might be due to excessive yeast in the bottom of the bottles.

I hope i posted in the right section.

Chill haze can be reduced by a few more days in the refrigerator. Was the yeast compacted in the bottom of the bottle? If not, more bottle conditioning time might be required. Did you pour the yeast that was in the bottle into the glass? Suspended yeast will darken the beer in the glass.

Extra yeast is not required for bottling, except for some higher gravity beers that have been aged for more than six months.

 

[ldtagtrip]

No yeast was poured in the glass and yes, there was a litle yeast in the bottom of the botle.

that is extremely dark. are you sure you used pilsner and MO?

The main cause of darkening after fermentation is oxidation. But if it tastes great, then just drink it and enjoy as oxidation gets worse with time. If the flavor isn't yet impacted, that's a good thing.

If the beer was dark earlier, it would be recipe related (maris otter is pretty dark compared to pilsner malt and a 90 minute boil would make it darker). It may be a combination of the 20% MO and the long boil, plus some oxidation, to make it darker than expected.

The thing that jumps out at me is:

one step sanitizer left in the botle.

One step is *not* a sanitizer. It's a peroxide based cleaner. It's possible, depending on the amount in the bottle and the strength of the one step solution, that the residue of one step caused an oxidation reaction in the bottle.

You need Star San, which *is* a no-rinse sanitizer. After cleaning your bottles with One Step, rinse well. When bottling, dunk the bottle in properly diluted Star San, ensuring that the entire interior surface is wetted.

Oxidation is my guess.

 

[ldtagtrip]

When the beer was botled it was nicely golden but hazy because i didnt perform a protein rest. It turned dark after about 3 weeks in the botle.
How do i prevent oxidation? Should i change the way i botle?

 

[The_Bishop]

As I stated earlier, you need to use a sanitizer. One Step is *not* a sanitizer.

How long did you leave the beer in the primary fermenter before bottling? Your beer was not hazy because you didn't use a protein rest. It probably had a lot of suspended yeast.

What is your bottling procedure? You need to transfer to your bottling bucket on top of your priming solution, as gently as possible with no splashing. The same goes for filling the bottles. The less agitation, the better.

 

[ldtagtrip]

I'll change to star san.
Beer was in the primary for about 16 days.
the issue was that i added extra yeast from the same batch for quick carbonation(mistake).
My botling procedure needs lots of improvments. I splash quite a lot and it takes a while until i cap them.

Thank you very much i'm going to fix all my issues for the next batches.

The bottling wand with the spring tip works very well. Attaches to the spigot of the bottling bucket with a 3 inch piece of tubing. The three-eighths inch wand uses five-sixteenths inch tubing for a tight fit.
