Lager - removing sulphur after fermentation
I decided to brew my first lager, so I've brewed a Helles.
On a recommendation I've used WLP833, and fermented at 9-10C for a week before gradually raising the temperature over a few days to 18C. Just shy of two weeks now and gravity is down to 1.008 and with a forced diacetyl test there's no hint of diacetyl in there, so I think we're done on the fermentation side.
The only thing I'm getting is a whiff of sulphur. Not massive, and the beer tastes nice, but the sulphur is on the nose. I'm presuming it'll just lager out over time now?
Should I just drop the temperature down to 0C and let it lager on the yeast for a few weeks before I bottle, or is there anything else I need to do to help get rid of the egginess?

Re: Lager - removing sulphur after fermentation
I've done a few lager kits using lager yeast and only 1 all grain lager (2nd all grain lager is in the FV now). They've all had the sulphur smell when young. I've never done anything special, just aged in the keg and they turned out great! The sulpher smell goes all together.

Re: Lager - removing sulphur after fermentation
take the temp down to 15c and give it another week. you could transfer to a seperate vessle to do this as you can use the yeast cake for another brew while the yeast in suspension cleans up
Re: Lager - removing sulphur after fermentation
You just need to wait. It'll go in time. Don't worry about it.
I've been there a few times with those types of yeasts, you just need to patient - I think sometimes we are too used to ale yeasts, although they throw off esters, they are still drinkable young. You'll see the difference though, lagered beers are so clean in a side by side tasting.

Re: Lager - removing sulphur after fermentation
As predicted, it went - I lagered it for 3 weeks below 1C, then fined with gelatin and bottled. After a week in the bottle it's looking and tasting great, just needs a little more carbonation.

Re: Lager - removing sulphur after fermentation
Your lager will definitely improve over the weeks. I kegged (PB) a Heineken all grain clone 12th Feb and filled 4 bottles. I been sampling them every week since. Just cracked the last bottle and no sulphur smell at all. Truly impressed with the brew, real full on continental taste to it. I'll transfer the lager from the pressure barrel to a sankey and force carb in the summer. Should be star bright by then.

You can always put some sanitized copper wire in lager tank, this helps with removing sulphur.

I've never heard of that, how does that work?zgoda wrote:You can always put some sanitized copper wire in lager tank, this helps with removing sulphur.
Re: Odp: Lager - removing sulphur after fermentation
Chemistry, simple ion exchange. SO3 ion oxidizes to SO4 and gets trapped by Cu. Or something like that, I stopped learning this like 25 years ago. Personally I just wait for it to dissipate naturally.

Re: Lager - removing sulphur after fermentation
If it works, it works! I normally leave my lager a good 10-12 weeks before drinking. They mellow quite a bit by then and turn out quite crisp.
Re: Lager - removing sulphur after fermentation
Copper will end up oxidising the wort. I wouldn't do it at all.
It will still need a conditioning phase of at least 3 weeks at -1 to 1.5C.
Indeed the taste will improve further and the sensory perception much more rounded. It's too early to call it. Give it more time.
