What is the effect on a beer when it has been Light Struck & how easy is it to Light Strike a beer?
I ask as my last brew has a strange, almost sour bitterness to it, which I don't much care for.
The fermenter bucket (Primary) and then the King Keg (Secondary) weren't in direct sunlight, but I guess were in a fairly well daylight lit place. I have had this taste on one other brew I made last Xmas too.
I will try and cover them in something or place in a darker area for the next brew to see if it makes a difference.
Light Struck/Skunked Brew.

Deffinately not like Skunk P155. Have smelt that when in the States... Poo!!!
Not really a vinegar taste either, as have tasted that in a lot of Pubs when the Land Lord hasn't sanitised his equipment very well.
It shouldn't still be green, as it's been maturing for around 2 months now. Another I made last Xmas still has this taste too.
Maybe it is some kind of infection then. Oh well, will need to get brewing again to stock up.

Re: Light Struck/Skunked Brew.
You will definitely smell skunked beer before you taste it. The sulphur compound mercaptan is produced when ultraviolet light reacts with certain hop products in the beer. The effect is very common in the US with all of the European lagers in green bottles. Mercaptan is used as the odorant in natural gas and it is quite stinky. If you don't have a noticible skunky smell in your beer it is likely another problem.Road Runner wrote:What is the effect on a beer when it has been Light Struck & how easy is it to Light Strike a beer?

No it wasn't a Porter. It was a Coniston Bluebird Bitter as posted in the recipe section below by tribs.ColinKeb wrote:its not porter is it?

I used Safale S-04 yeast & fermentation temp may have been a little high at around 22-23'c, but I would have thought that was ok though.
Now the weather has cooled down a bit, I should be able to ferment nearer 20'c next time.

I'm fairly sure I didn't over hop. I followed tribs's recipe to the letter/number.
I use a set of digital scales to weigh the hops/grain. I wouldn't expect them to be that far out of calibration to make a huge difference. Any way, they measure exactly the same as another set of analogue kitchen scales I have.
I won't give up on it just yet, I'll leave a while longer to see if anything changes. It's been in a KK (Secondary) for almost 2 months now, so I may rack it into a Corny to get it off any sediment that's built up in the KK.
