Yeast flavor, how long to condition?

[HealeyA87]

I brewed an all grain, 5 gallon Summer Ale (Sam Adams summer ale clone). It was in primary for 3 weeks. I have a big mouth bubbler with a spout for my fermentor. After sanitizing everything, I transferred from the big mouth to a bottling bucket, added my priming sugar as usual, and bottled. So the bottles conditioned for 2 weeks and then put in the fridge. I have slowly been tasting them to see whee they are. Tomorrow will be 4 weeks since bottling. This is my first all grain batch. I have brewed probably 10 or so extract batches between me and my buddy (we brew together)

So 2 weeks conditioning, followed by 2 weeks in the fridge. And as of today. The beer still has a yeast odor/flavor to it. Under bright light the beer appears basically clear. But I noticed today, under a dim light, there is a cloud in the beer. Not that the entire beer is cloudy, but you can see a cloud floating. The top 1.5-2 inches of the beer is super clear, but there was the layer below that that you can see the cloudiness....

After all that, my question is. How long will this take for it to fully condition and have the sediment settle and get rid of the yeast flavor. I assume that cloudiness I see is yeast that's still suspended. Over the last 2 weeks it has SLIGHTLY gotten better. But I figured after being bottled for 4 weeks, it should be ready by now. Is there anything I can do to help settle any remaining yeast?

The cloudiness you're seeing is chill haze. Leave'em in the fridge 5-7 days & it'll form & settle out like a fog. You'll also get thicker head & longer lasting carbonation in a week. Moreso in 2 weeks.

Even after being in the fridge for 2 weeks? I also have half the batch still In the closet that haven't seen the fridge yet. I haven't tried any of those yet. Only the ones that have been in the fridge for the last 2 weeks

Nothing you can do about at this stage aside from ensuring optimal carbonation and refrigerating the beers for prolonged periods before drinking. Pop them in the fridge. Use as needed (once they are fully carbonated).

The cloudiness could be related to a number of causes, some or all of which could be involved.

1: Starch haze as a result of incomplete conversion in the mash.

2: Wheat in the grain bill in large amounts.

3: Hop oils if the beer was dry-hopped. (this is not necessarily undesirable by some drinkers)

4: Protein haze (a.k.a chill haze) caused by coagulation proteins in response to lower temperatures. This will reduce with prolonged settling in the fridge and will disappear as the beer warm sin the glass. Achieving good hot and cold breaks during boiling and cooling minimize/eliminate this

5: Infection from unintended microbial invaders chewing on otherwise non-fermentable sugars in the beer.

6: Deficient levels of calcium can impair the flocculation of yeast. Some strains are less affected, some yeasts settle better than others.

7:Transferring from the FV to the bottling bucket via spigot can also introduce a lot of trub if the spigot's opening is too close to the level of the yeast. (I think this and protein haze are the likeliest culprits.)

Impossible to tell from your description which of these is/are the chief etiology of the beer's haze.

I guess my biggest concern is the yeast flavor. I couldn't care less how it looks. I just want it to taste better/less yeast

The yeast flavor is in all likelihood the result of your method of transfer from the FV to bottling bucket. All that turbulence near the yeast cake. Some is getting into the bottling bucket.

Yeasty flavors could also very likely be related to fermentation temperatures. Yeasty flavor is a very nondescript term. Hard to infer a lot of meaning there.

Yeasty means very different things to different people. I've not tasted yeasty beer other than a Hefeweizen which is whole other ball of wax.

How'd it look after 3 weeks in primary? did you do a mash of any kind? Any trub that got through the system would've settled out by now. Including chill haze. But starch haze will not. I've left beers with that problem in the fridge for a month solid & very little difference in clarity. More than 2 weeks conditioning might've helped. Unless it's starch or protein haze.

Hmmm. Guess I need to invest in a secondary.

Is there any chance it will settle out or get better over time?

with this being my first all grain, it's all just a learning experience. It was also the first time I used the big mouth with the spigot.

 

[Gavin C]

Hmmm. Guess I need to invest in a secondary.

That should have no impact on clarity whatsoever. I never use secondaries. Clarity without using a secondary is easily achieved with correct technique. There is no correlation between secondary use and clarity.

If it were me I'd lose the spigot from the fermentor. Many folks do transfer in the manner you describe way and report favorable results. Not my preference however for many reasons I won't bore you with.

Protein haze and chill haze are one and the same. Here is useful article to read if you feel that is what you may have. Sounds more like suspended trub to me though.

 

[HealeyA87]

Well, like I said. The clarity isn't my concern, it's the yeast flavor. I figured secondary would let any yeast, that did make it out of primary, settle out

 

[HealeyA87]

That's the exact article I was just in the middle of reading. Haha

A lot of folks use a secondary for this very reason it would seem.

IMO this is a very bad reason to use a secondary as it is not a solution to your problem but merely a crutch to minimize the effects of an error in racking technique.

Others will view this reason for a secondary vessel as sound. If you include yourself in that group a secondary would be a reasonable step.

The use of a secondary is a well beaten dead horse of a debate here on HBT and elsewhere in home-brewing circles. You should of course decide what you feel is best.

There are two kinds of yeasty flavored I can think of:

1. A greasy, dusty flavor I usually associate with low flocculating yeast. Kolsch yeast, for instance, can take a really long time to flocculate.

When you bottle carb, you get another cycle of yeast growth in the bottle. A low flocculating yeast can take more than 4 weeks to clear from bottle carbing.

If you used something like Wyeast 2565, I can see this happening.

2. Yeast bite, which tastes like putting a spoon full of baking yeast in your mouth.

Time will fix #1. I'm not sure anything will fix #2.

Thanks for the info guys(or gals). This is all a learning experience for me and the info is helping me further understand what I'm doing
