Does Wlp300 Hefeweizen Give Off Sulphur?

[andreic]

Hi all,

I brewed a hefeweizen last weekend (3kg wheat, 2.5kg pilsener, hallertauer at 60 min to 12 IBU). I drew off about 600ml for my yeast starter with a WLP300 Hefeweizen yeast. The yeast starter threw off a minor sulphur smell, but tasted ok. My beer has been fermenting for 2 days now at between 17-19c and tonight it has a strong sulphur smell.

I have used this yeast 3 times before and don't remember the strong sulphur smell. Is this normal? I'm not panicking yet but would be awful disappointed if AG number 3 is screwed...

cheers,

Andrei

thats prolly a sign that the yeast is stressed.

had it once with a 3333 wyeast strain and the beer had a taint that refused to go away,(similar to autolysis).
Should be all fruit and bubble gum if its happy.

give it a swirl and let it warm up (22c) and it may clean up the off characteristics. :blink:

I will let it warm up and report back over the next day or so... AG number 1 was a hefe and pretty good drinking so I'm going to be very disappointed if this one doesn't work out ok. :blink:

Well,

I have tried to let it warm up - its at around 20c at the moment. I had to have a sample to check on it... The smell has almost gone away, but I'm not getting banana and bubblegum which kind of sucks. It tastes ok so it'll be pretty drinkable if not the finest example of the style. It has gone from 1.044 to 1.012 in 2 and a half days! That is pretty quick in my opinion...

cheers,

Andrei

Checking the whitelabs site they recommend bottom temp of 20degs, but I know some brewers advocate fermenting as low a 16deg, if you choose to use the 30deg rule where pitching temp + fermenting temp should = 30degs.


Edit: Reading a bit further;

WLP320 American Hefeweizen Ale Yeast
This yeast is used to produce the Oregon style American Hefeweizen. Unlike WLP300, this yeast produces a very slight amount of the banana and clove notes. It produces some sulfur, but is otherwise a clean fermenting yeast, which does not flocculate well, producing a cloudy beer.

Have you got the wrong yeast in the tube ? :huh:
