I haven’t used this strain in years and the last time was pre-ferm freezer. I opened the lid this morning to a bit of sulphur. Not as bad as I have smelled from friends 34/70 fermentations, but it’s noticeable. I’d rate it at the level of fresh hard boiled eggs, noticeable but not off putting.
I’m not concerned about it as I am only two days in, but I wanted to see if others noted the smell before.
68° for three days and now slowly raising to 72°. It’s faded but I haven’t pulled a sample to taste. Like I said, it wasn’t strong, but it was there. I’ll pull a sample Saturday, hell I might even keg it Saturday if it tastes good (7 days). Activity has died way down and it is starting to floc.
That was pretty much my ferm profile as well (although I started my old ale at 65F for a couple days to control the higher fusel alcohol production). I have always wondered if sulfur production is a result of stressed cells?
There supposedly is a link between sulfur in beer and lack of contact with copper. I’ve always used a copper IC and (except for hefe, wit and a few lager strains) I never get any sulfur. What sulfur I do get from these strains always dissipates in a week or two. I’ve heard that you can test this out by stirring a sulfur-y beer with a short piece of copper tubing, and the sulfur disappears. As for stressed yeast causing sulfur I’ve heard that to be the case - don’t know to what extent or scenario.
Figured you did. Honestly, thinking back, I think the last time I used 1028 was on a RIS (I like it for porter and stout), and the beer stayed in primary for a solid month - so any sulfur would’ve been gone by then. Don’t remember it prior to that. For 2 or 3 years though I’ve been using 1450 for brown, porter and stout so it’s been a while since I used 1028 very often.
Pulled a sample and it seems to be done at 83% ADF. Can’t pickup any sulphur in the nose, maybe a touch in the flavor. Super hazy which was expected with this yeast, so that might be jacking with my perception. Going to start crashing on Saturday and will keg Monday or Tuesday with gelatin to fine.
The beer is pretty boring which I guess I expected considering it is a New Albion based Cascade/2-row smash. I think I should throw an ounce of Cascade in the fermenter when I go to crash.
You should get even more sulfur as you increase the sulphate content. It is referred to as the “Burton snatch.”
Wyeast 1028 is Worthington’s primary strain. It was selected using the union system, which is why it is so powdery.
I like 1028 for my Am brown ale since it lends a minerally note to the beer. I’ve not noticed a sulfur note in the many times I’ve used it. Since you have a copper IC, you shouldn’t be copper deficient. I’ve got to believe that this flaw will clear up pretty quickly.
How Wyeast names came about boggles my mind sometimes. After all, they named the prototypical German tetraploid strain Wyeast 2124 Bohemian Lager. If W-34/70 is indeed the Frohberg strain, then it originated in Grimma, Saxony.
