I started a Belgian Specialty Ale this last Monday using the recipe below. I’ve re-suspended the yeast a couple of times using a home made Lazy Susan table so as not to introduce any oxygen. Just this evening I seem to be getting some faint sulfur/egg odors. Is everything ok? What’s going on? Is there something I need to do in order to prevent a batch of swill or will everything be fine?

Thanks,

Belgian Honey White
Extract with Specialty Grains
Makes 5 Gallons

Ingredients:
• ½ lb Flaked Wheat
• ½ lb White Wheat Malt
• ½ lb Belgian Pilsner
• 6 lbs Liquid Wheat Extract
• 3 lbs Honey
• 1 oz Ahtanum Pellet Hops
• ½ oz crushed Coriander
• ½ oz Bitter Orange Peel
• ½ oz Shredded Fresh Ginger Root
• ½ oz Fresh Lemon Zest
• 4 ½ oz Corn Sugar (priming sugar)
• 1 capsule of BrewVint Yeast Fuel (nutrient)
• Yeast: White Labs, Belgian Wit Ale, WLP400

Directions:
Sanitize everything.

In a 16 – 20 quart stainless stockpot, bring 2 ½ gallons of water to 155°F and turn off heat.

Put the crushed grains (½ lb Flaked Wheat, ½ lb White Wheat Malt, ½ lb Belgian Pilsner) in a grain bag and steep for 15 minutes, agitating the grain bag with a stainless spoon. Remove the grain bag and get all the water out of it then discard.

Return to heat until boiling then turn heat off once again and move the stockpot to a cool burner. Stir in the 6 lbs of Liquid Wheat Extract and 3 lbs of Honey until completely dissolved then heat the mixture until boiling.

Reduce heat to achieve a good roiling boil without it boiling over. Add ½ oz of Ahtanum Hops and set a timer for 60 minutes.

Add the ½ oz crushed Coriander, ½ oz Bitter Orange Peel, ½ oz Shredded Fresh Ginger Root, and ½ oz Fresh Lemon Zest for the last 15 minutes of the boil.

Add the capsule of BrewVint Yeast Fuel for the last 10 minutes of the boil.

Add the last ½ oz of Ahtanum Hops for the last 5 minutes of the boil.

Cool the wort to around 80°F and pour it into a clean 6 ½ gallon glass carboy for primary fermentation.

Add enough cool water to make 5 ¼ gallons.

Check the Original Gravity. It should be around 1.066.

Pitch your yeast (White Labs, Belgian Wit Ale, WLP400).

Aerate thoroughly.

Attach airlock and blow-off tube.

Primary fermentation should slow down after 5-7 days. At this point rack into a clean 5 gallon glass carboy for conditioning (secondary fermentation).

Conditioning should last around 5-7 days. Final gravity should be around 1.016. At this point rack into a clean 5 gallon glass carboy for priming and bottling.

Pour 1-2 cups of water into a small pot and bring to a boil. Stir in 4.5 oz of Corn Sugar until completely dissolved (approximately 1 minute) then remove from heat and let cool to 80°F or cooler.

Pour the cooled sugar water into the bottling carboy and mix gently but thoroughly.

Bottle and age for 3-4 weeks.

Brew Log:
03/17/2008
4:00pm: Initial fermentation started.
Original Gravity: 1.0675
Sugar by weight: 16.46° Plato
I didn’t have ½ oz of lemon zest so I just used ¼ oz.

03/19/2008
10:00pm: I haven’t seen an excessive amount of foam so I removed the blow-off tube and re-suspended the sediment using a home made Lazy Susan table.

03/21/08
9:45am: I re-suspended the sediment using a home made Lazy Susan table. Fermentation is still quite vigorous with bubbles coming faster then 1 every second.
8:00pm: I’m starting to detect a faint sulfur/egg odor.
 
Hey dude!

In my experience with wine yeasts (an for the record I have only used ale yeast once) a sulfur odor comes from nutrient deficiencies or other stress. I would recommend adding another dose of nutrient, what is the weight/dosage of this stuff you used? I am not familiar with it at all.

I'm most familiar with DAP and Fermaid K, if I were making a mead and this happened I would add one gram of one of these (FerK is preferable this late, but either is way better than sulfur) (1/4 tsp = ~1 g)

Temp or pH may be a factor as well, but I cant offer you much there.
I may be totally off base, I have no experience with beer making at all, anyone else to chime in?

Best of luck!

To borrow the immortal words of Charlie Papazian: Relax, Don't Worry! Have A Home Brew! (hereinafter known as RDWHAHB!) The dude didn't have a clue when it came to meads but he taught me how to brew beer.

You are only into the fourth day of your ferment of your beer. Just keep things swirled up (gently, don't add any oxygen) two or three times a day and the odor will go away.

Out of curiosity, what is your current SG? I'm betting you are pretty much done as far as primary goes.

You've got a lot of conflicting spices in here that might give an sulfur odor, particularly the coriander. It's a very complex herb. Mix that with the ginger and you'll definitely get some "hotness" on the nose but no tearing in your eyes.

Here's the thing: In a mead you are heavily dependent on additional added nutrients just to make it work. If a mead gets short of nitrogen, you'll end up with an "oniony" or "sulfur" odor.

In a beer, especially one that has as many adjuncts as this one, nitrogen and nutrients are probably the least of your worries. I would bet you are just smelling the latest chemical reaction of those adjuncts. They change from day to day.

The scottish ale I started last Sunday has some funky notes right now too. It's easy to confuse the smoke from the peated malt I used with sulfur. But I know my ingredients. And I've brewed beer before. I know how different blends of spices blend together over time. Both in the the nose while fermenting and over the years that they might sit in a bottle.

In other words, just because you've read about sulfur being a bad thing in mead on this site doesn't mean it's a bad thing with beer. With that spice load, anything is possible!

Give us your current SG and we can help dial it down to specific causes. But I'm betting that time will be your friend here.

In other words: RDWHAHB!

Yup, I agree with Wade. Sulfur in mead is a sign that you should be worrying. Sulfur in beer is just a funny smell. There are lots of fun sulfur compounds in beer wort (originating from the malt) and quite a few will get volatilized during the ferment. No worries, just keep the closet door closed. ;D
 
Well, it may or may not be a problem. Belgian ale yeasts may produce a sulfur/rotten egg aroma for a while, but to my knowledge, those are usually in yeasts such as trappist ale and other higher gravity belgian ale yeasts.
I had a batch of a Midas Touch clone that I made once that had a horrible sulfur aroma from the airlock, but it turned out fine in the end.
I have made many Belgian wits, but none of them ever had the sulfur aroma (could be from contamination).
I would give it some time b/c it would be a crime to throw out a nice Belgian Wit.

Thanks all. The odor disappeared after another day or two . . . but the fermentation is still quite active. Is this a problem?

I’ve had it in primary for almost 10 days now and there is still 1-2 inches of foam at the top, not very much trub settling to the bottom, and the bubbles are still coming at a rate of 1 every 10-11 seconds.

Should I just leave it in primary until the foam goes away or the bubbles slow down? Would it be better if I go ahead and rack it at the two week mark anyway and if so, should I try to get some of the foam off the top into the secondary?

Thanks,
evenstill
 
The first time I used a Belgian yeast, I racked & bottled after 2 weeks even though there was still krausen (foam). I found out later I should have just waited (though the beer was fine, just a little extra yeasty). Belgian yeasts just like to hang on at the end and take a little longer to clear out. Just give it some time; there's no rush to move the beer at this point.
 
I totally agree. You could always take a SG reading, but probably just leave it in the primary. Don't worry about the "2 week rule." A month (or more) is often needed with higher gravity beers.
Remember that the purpose of the secondary "fermentation" is really more for conditioning, so ideally, most of the fermentation has already finished when you rack to the secondary.

cheers,
vahan
 
Will the krausen sink to the bottom when it's finished? What should I look for other then airlock activity (I'm leery about opening it constantly to check the gravity)?
 
Yeah, eventually the krausen will fall and the yeast will flocculate. Give it another week and take a peek to see how it's doing.
