Off flavour - what went wrong.
Hi
I recently brewed an american amber ale from extract. It spent 7 days in the primary, 9 days in secondary and then I bottled it. Both primary and secondary fermentation took place in a room with a fairly constant temperature of around 19C, however, during primary fermentation I stuck a thermometer into the liquid itself and it read 23.5C (I'm guessing that fermentation is exothermic). It has been in the bottle for about two weeks so I decided to give it a try and it has a very sweet/medicinal off-flavour - barely palatable. Any ideas where I went wrong? Would the high primary fermentation have caused these flavours and will it improve with conditioning or should is it a drain pour?
Cheers

A fine beer may be judged with only one sip, but it's better to be thoroughly sure.

Did you treat your water to remove chlorine?
23.5C is a tad high but not too high IMO.

Re: Off flavour - what went wrong.
I didn't treat the water, but then I never do and have never had a problem before. I've also brewed an IPA since and it seems OK so far. The off-flavour isn't really chemical, its more medicinal - very sweet like a cough syrup.

Re: Off flavour - what went wrong.
In general, never be too quick to pour beer down the drain, especially as it is already bottled/kegged. Just keep it for a few months and sample it now and then.
When you say it is sweet, did you check the final gravity?

Re: Off flavour - what went wrong.
YEs, OG was 1052 and FG was 1012 so there shouldn't have been too many infermented sugars left. I was wondering whether the primary solution wasn't properly mixed in before bottling and some bottles have more priming solution than others. This is the first time I've bottled a beer (in the past I've always dispensed from a barrel). I racked into a bottling bucket bucket with the priming solution at the bottom but didn't stir it or anything - just assumed that the swirling of the liquid flowing into the bucket would do the job.

The FG looked fine. Give it some time and it may come good.
Even if it doesn't then you may aquire a taste for it!

It could also be an infection.

Re: Off flavour - what went wrong.
I've had a few bews like this and unfortunately they're beyond repair, it starts off as a medicinal cough syrup off flavour and then the longer it conditions the more the flavour will turn into a nail polish rempver type taste, their is nothing that can be done and my bee4rs were undrinkable after about 3 weeks,
I put it down to high pitching and fermenting temp, i was fermenting in a room with a constant temp of 18c but my pitchiong temp was very high and it was taking about 2 days to drop down to 18 and initial fermentation was nearly completed then.
Make sure you drop your beer to at least 20c before pitching, thats how I solves it anyway

Re: Off flavour - what went wrong.
I opened another bottle last night and it was fine so it was either a contamination in the first bottle only or I need to mix in the priming solution better next time, I think. I'll leave the remainder to condition for a few more weeks and see how they go.

Re: Off flavour - what went wrong.
Excellent news. So it looks like you may have a beer lottery. Will the next bottle be good or bad?
The absolute best way to find out is to get a mate over, prfereably one who is sceptical about home brew, and get him to choose a bottle. It's bound to be a bad one so you have more chances of choosing a good one for yourself!

Re: Off flavour - what went wrong.
I'm wondering if the off tastes might be down to incomplete rinsing of some of your bottles.
Best wishes

Boingy, I like your thinking. I know just the blike too - he normally drinks Fosters so he'll be used to drinking sh1te beer anyway.

Re: Off flavour - what went wrong.
I've bottled before without stirring the priming solution into the bottling bucket, I never got a medicinal taste but it was a carbonation lottery, some were pretty lifeless and some just left you stood there looking at an empty bottle and a fountain of beer heading up into the air... luckily none exploded

Re: Off flavour - what went wrong.
I'm fairly sure now that this is as a result of not mixing in the priming solution properly. I bottled it into a dozen swing-top bottles first and the remainder into normal bottles. The first bottle that I opened was a swing-top and was too sweet, the second was a normal bottle and was OK. I opened another swing-top last night and again it is very sweet and way over-carbonated - it foamed up like a bottle of champagne when I opened it.
