Oxidation??

[cgrivois]

Im constantly getting an off taste in all of my light beers, kind of stale, dull taste, cant compare it to wet cardboard as Ive never tried any. Could this be caused by Oxidation? I ferment in a botteling bucket, then drain through the spigot, using a hose to the bottom of my secondary, or keg if choose not to secondary. It may splash a little but nothing I have been concerned about. I did just read that you should not aerate wort that is above yeast pitching temp. In my process, when Im done my boil I drain my kettle into my fermentation bucket via opening the spout and letting it fill the bucket, splashing around. I then chill in my fermentation bucket using my imersion chiller. Could I be Oxidsing my beer by draining it from the hot boil kettle into the bucket?

That is not your issue.

Stale would tend to indicate oxidation. Oxidation doesn't show up quickly. When do you first notice this (time from brewing/time from packaging). Does it get worse with time?

If you have this in the first beer from the keg, in a beer that is 4 weeks from pitching yeast, then oxidation is not your problem. Oxidation accelerates aging/staling of the beer and will happen over time.

could the taste be coming from pouring near boiling wort into a plastic bucket. i would cool the wort down before before transferring to plastic.

It shows up quick. At first I thought it was green beer, but it doesnt realy go away.

Thats what I do. Anyone want to elaborate on this?

What about headspace in my fermentation bucket? Usualy have 5.5 gallons in a bucket.

That shouldn't be an issue as the CO2 created during fermentation would push out the oxygen.

Bucket manufacturers don't recommend putting hot liquids in their buckets.

I doubt it is good for the integrity of the bucket. No clue if there are any safety implications.

I've tried to see what hot side aeration would do to my beer by pouring boiling hot wort into a fermenter bucket from as high as I could hold the pot of boiling hot wort. I made two batches of the same recipe and sampled them to see the difference it would make. At a year, there still was no discernible difference in the two batches so I would say that that isn't your problem.

Lighter beers don't hide flaws in the flavor like darker beers can. Have you considered the water source as a possible problem? Also, darker beers will more readily bring down the pH during the mash. Your lighter beers may be mashing at too high of a pH.

My PH has been fine according to my meter, and I have a ward lab test on my water which I don't think showed any concern.

They are probably more concerned with liability than the integrity of the buckets. Mine have held up well under the onslaught of boiling wort.
