Caused what? We don't know what his fermentation temperature was, and we don't know if his beer has any issues other than being under-attentuated.Moral of the story is, your fermentation temp probably caused this, as did mine.

Your English is fine, no need to apologize.I appreciate all the replies and I apologize for my broken English.
Yeah a freezer will hold in heat as well as it will keep it out and fermentation will create quite a bit of heat. That said is 77.5F enough to wreck a batch? I let my fermentations all rise naturally at the start in my basement and commonly hit 72-73. I just did a recent Fat Tire clone that turned out great. Just curious if I'm that close to some edge.I recently did a New Belgium clone of their "Fat Tire" Amber Ale. In a huge stand up freezer w/Stainless conical inside, but in a garage that was 50F (10C). Figured I didn't need to turn on the freezer/temp controller, it was plenty cold.
Uhh, Wrong...
OG of 1.062 (little high for this clone) and using US-04 it went to 77.5F (25.3C) all on it's own... Created a horrible alcohol aroma, and might get dumped out because of it. I never would have guessed it could raise the temp of the entire freezer in such a cold garage, but I guess they're insulated pretty well. Who knew, lol.
Admittedly, now another week later at 60F (15.5C) It's a little better, but still has a nose that makes you want to dump the glass. Doesn't taste terrible, but it's not what I was expecting.
Moral of the story is, your fermentation temp probably caused this, as did mine. This could be my second 10 gal batch getting dumped out in the last month. What stinks is that the equipment is again tied up with a batch of beer I'm trying to save by letting it sit. Where it should be in kegs and in the kegerator already and I should be making another batch of something else. I suppose I could keg it and do something else. But I so enjoy cleaning kegs, I hate to stick bad beer in 2 only to dump it and have to clean them again for nothing....
Mistakes are bad...
Fermentis says "ideally 18-26°C (64.4-78.8°F)" for both S-04 and US-05.Just curious if I'm that close to some edge.

I understand, but my temperature never went above 25.5 c which is within the ideal range of the us05I recently did a New Belgium clone of their "Fat Tire" Amber Ale.

Well, I should certainly be one of the more experienced brewers then. Lol.Good judgment comes from experience, and experience comes from poor judgment.
He said in the OP about an alcohol taste, so I took that to mean fusel alcohol. Commonly caused by too high a ferm temp.Caused what? We don't know what his fermentation temperature was, and we don't know if his beer has any issues other than being under-attentuated.
Fermentis US-04 says on the package 58F to 68F. Not sure where you're getting those numbers from, but perhaps there's different info at different sources, such as their website or old info.Fermentis says "ideally 18-26°C (64.4-78.8°F)" for both S-04 and US-05.
People who have temperature-controlled fermentation chambers will probably say that the real optimal range is much narrower. People who don't have temperature-controlled fermentation chambers will probably say that the real optimal range is much wider.
I admit, I'm talking about US-04, but yours went 1F higher than mine and mine definitely has a problem... Just say'n. It's something to consider.I understand, but my temperature never went above 25.5 c which is within the ideal range of the us05
He also said he tasted it at one week. It's a pretty big leap to assume he has fusel alcohols before the beer is finished.He said in the OP about an alcohol taste, so I took that to mean fusel alcohol. Commonly caused by too high a ferm temp.
It's from their website, which also says that the information on older packages is incorrect.Fermentis US-04 says on the package 58F to 68F. Not sure where you're getting those numbers from, but perhaps there's different info at different sources, such as their website or old info.
Hmm, I'm talking about packages that came in the mail on Friday 4/28. Not very old...It's from their website, which also says that the information on older packages is incorrect.
I suspect that the packaging is much older than the yeast inside. They might have years' worth of pre-printed packaging lying around and they've decided that there's no reason to scrap it since the info on the label is more conservative and the updated info is available online.Hmm, I'm talking about packages that came in the mail on Friday 4/28.

Nope, you are correct. The very latest packages that came on Friday have the new recommendation on them. But the ones I had received in the previous shipment a couple weeks ago, those still had the old recommendations and of course I don't need to read the package for the yeast I have used for 15 years, lol. I mean I had read the package and had just looked at the stuff this Sunday when I was brewing but admittedly I had picked up the package from the most recent Brew, not the brand new packages.I suspect that the packaging is much older than the yeast inside.

They have in fact altered the recommended fermentation temperature range for their yeasts. You are, of course, free to be skeptical about why.Color Me at least a little skeptical that they are now altering the recommended temperature for the yeast. After all these years, if the strain has changed that much then I guess it isn't Us04 anymore. Is this marketing because they figure it will sell better if it's okay at room temperatures?
And I pitched at 22C.
this thermometer is close to the fermenter, it shows the room temp and it's very accurate, I've used it for incubation with %95 hatch rate, this is the temp in the past 6 days
So that has been the issue here, yes the ambient temperature never reached 26c, I didnt put a thermometer in the wort after I added the yeast, cause people said the metal sensor of her thermometers will cause problems, but I kept touching the side of the vessel and I don't think it ever got that warm, the room is cold all the time, there's an AC on all the time, like if always felt cold when I touched the vesselWhat was the temperature of the wort/beer in the first few days of fermentation? You mentioned that it had reached as high as 25.5C. But was that 25.5C measured with this same thermometer that's "close to the fermenter," i.e. basically the ambient temperature? With an ambient temp of 25.5C, The temperature in the fermenter could easily reach 28C or even 31C, depending on several factors. Fermentation is exothermic.
I'm gonna do it next week, now I can't open the fermenter, I don't wanna add oxidation to the present issues of the beerMaybe I missed it, but did you ever check the gravity again? Can you remind us what your OG and expected FG were?
Sorry I'm a little confused. If you can get a sample to taste why can't you check the gravity of the same sample. You have a spigot on your fermenter, right? You don't have to open the lid to get a couple of ounces to test.I feel a little burn now, when I drink the sample, but it's not that bad, it's just the alcohol flavor and aroma is dominant
I didn't like my first porter either after having done many successful pale ales and IPA's. I'm not happy with my second porter either but it's better than the first.
Maybe the third time will be the charm!
I firmly believe that's my issue. I'm making corrections one step and one batch at a time just to see what the improvement is.You might want to take more interest in water chemistry.
The sample for tasting is way smaller than the sample needed for a gravity check, if I keep taking samples, the water will rise in the blow off tube and eventually reach the fermenterSorry I'm a little confused. If you can get a sample to taste why can't you check the gravity of the same sample. You have a spigot on your fermenter, right? You don't have to open the lid to get a couple of ounces to test.
What are you floating your hydrometer in? I need 100 mL tops, which isn't much more than a taste.The sample for tasting is way smaller than the sample needed for a gravity check
I'd be wary of doing anything to just mask the flavor. If you really have significant amounts of fusels (and I'm not convinced you do) then you don't want to drink them. I don't know if restarting fermentation will let the yeast clean them up or not.I've heard that back sweetening reduces the tart and fusel alcohol flavor, I also read somewhere that crystal malt, if steeped at the end of the boil, will have an attention rating of 50 perfect, what if I boiled some crystal 120L and added it to the wort? Fermentation will start again and it'll be a bit sweeter and maltier, right?
I'll find the recipe, it's on my computer on beer Smith, but I remember there was like 6 percent of crystal malt and 4 percent chocolate malt, black patent wasn't more than 3 percent@Ali01 - what's the recipe? Maybe it just wasn't a good recipe. Any chance you're drinking a super young beer that's got a huge amount of chocolate malt in it, or something like that? Maybe you are confusing that flavor with something else? Too much dark malt can be a little harsh.
You spelled months incorrectly. Another 2 months will make a difference, two weeks may not be noticeable.I'll let it age for another two weeks, if it didn't get better, I'll boil some crystal malt and add it to the fermenter and let the yeast eat away at the fermentable sugars, when it's done, that should leave some residual sweetness in the beer which reduces off flavors, right?
