Haha...well, now what? I'm guessing I shouldn't use it, right? I guess I could build up some bottles dregs or just buy a new pitch.Yikes, never seen anything like that. There are occasional issues of sour beer going purple-ish when exposed to oxygen... but nothing like that!
I can absolutely move it to the keezer if need be. I'll pull a sample tonight and see how it tastes. Thanks.The risk is that the Brett will be converting that acetic acid to ethyl acetate, which has a strong solvent character at higher levels. Depending on how it tastes now, cold might be better if it is an option.

Is that harvested yeast in a small jar?
Any chance you sanitized w iodophor and fed fed it new wort too?

IIRC, I followed my normal routine on the stir plate when I spun this up last year. Just a few days to let it ferment out. I will say, however, I did not decant this one after cold crashing like I normally do. We know brett/bugs don't crash out as easily as sacc does, and I didn't have time to wait weeks for it to fully crash out, so I pitched the whole thing.Hello all.
I ordered a pack of this the last time it was available from Bootleg and I'm getting ready to use it soon. This will be the first time that I've made a starter with Brett. I've read that Brett starters need more time to build up, as compared to Sacc, but I wasn't sure if that was the case with this since it's a blend of Sacc, Brett and Lacto.
So my question is, how long are you guys letting this spin on the stir plate before use?
Thanks in advance!
Excellent, thanks for the advice!IIRC, I followed my normal routine on the stir plate when I spun this up last year. Just a few days to let it ferment out.

What are you brewing?Excellent, thanks for the advice!
I'm going to brew a low abv saison. Probably around 4-4.5%. I'm thinking all Amarillo and pushing the ibu's to around 35.What are you brewing?
I just brewed with it yesterday: a hoppy petite saison with Amarillo and Crystal. Last time the only hops I used were a 2-ounce dry hop, and it was nicely tart. This time I hopped it to about 23 IBUs, and I'm only doing a 0.75 ounce dry hop in a 3.5 gallon batch.
Damn, I've only used it once, but haven't gotten that. Mine got too acetic, but that was my fault for exposing the brett to too much O2. Gonna have to blend that out.Has anybody else gotten any sulfur smells from this blend? I made a 1-liter starter from a 6-month old pack, and pitched it almost 3 days ago at about 73F. It's been fermenting at ambient temps since then which have ranged from 68-74F. The thermometer strip on the bucket got up to about 78F or so at the height of fermentation, and now it's sitting around 72F. Fermentation took off pretty quickly, and at first it was putting off amazing hoppy smells, but then about 2 days in I could smell a sulfur note.

OK...false alarm. I'm just being paranoid. There's no sulfuric smell. I think I'm just looking for something to worry about. I should have just listened to my wife when she said she only smelled hopsHas anybody else gotten any sulfur smells from this blend?

Looking forward to it, I've never blended before. Thankfully the acetic is not super powerful. I did some initial tastings this weekend and it's looking like possibly around 70/30 blender/base. Going to try and nail that down this weekend since they're both ready to go.Good luck. Hard to do. Acetic really sticks around and seems to have a low threshold. Let is know what works.

Glad to hear! I had one batch that went a little sulfury with my original blend. I believe it was a similar situation, reviving it after a few months in the fridge. Eventually pressurizing the keg and venting scrubbed it out.
Looking for advice on how to deal with an old slurry of the Mad Fermentationist yeast blend for a new beer.
I saved about a 1/2 liter of yeast from one of my brews last year that used the MF yeast. This 1/2 liter was probably 4 generations in from the originally purchased yeast. All the batches were between 1.044 and 1.054 for this particular slurry, and most were fairly low hopped (I branched out with a different MF slurry for a super high gravity beer - another story).
The last beer with this was brewed on 7/30/17. So my questions are...
- How best to make a new beer with this saved slurry?
- Do I create a starter to wake things up? If so, how much slurry do I use in the starter? What sized starter?
- Do I just pitch the whole 1/2 liter into my next beer without making a starter?
My plan is to brew the same beer that I first brewed when I purchased this yeast last year (recipe listed much earlier in this thread). It's a fairly light and low hopped saison.
I've only every used fresh slurry in the past and never saved one for so long (almost 8 months). I really like this yeast blend and figure I'll start over sometime this summer with a freshly purchased batch, but I want to keep experimenting with it and see what I get with this slurry.
Thanks for any suggestions!
I would definitely make a starter for sure. I don't know that I would use the whole half liter. Honestly, I think I might make a 1L starter to get it going, cold crash, decant liquid and then make a 2 L starter. Pour half of that off to keep for any future beers and ditch what is left from your stored yeast. But, I think I would step it up twice just to make sure it seems healthy and good before dumping it into a beer. I recently used some that was a couple generations old and had sat in the fridge for about 3 months. I made a 1 liter starter with it. Used it to ferment a kettle sour (lacto) and then added cherries to it. Bottled it today - it was great.
Thanks for your thoughts Braufessor. I like the idea of a two step starter also. Just not sure how much of the slurry to start with. Since it's packed pretty dense after all these months, maybe I start with about 3/4 cup (177 ml) and step that up twice. Totally guessing here.
You don't have to have a stir plate for starters. Before I had one, I did my starters in growlers. I'd just swirl it around whenever I thought about it or walked by.I just pre-ordered from Bootleg Biology and expect my yeast some time in December. That said, I don't have a stir plate to do a starter. (I got excited and ordered without thinking things through.) Any experience with pitching directly versus creating a starter?
In addition, since I want to harvest this, I should be able to just grab a few jars of slurry after I transfer to my bottling bucket, right?

Yeah, but you don't even need an air lock. I just cover the top with a piece of sanitized aluminum foil. Just shoot for a 1.040ish gravity.So I should just heat up and cool some DME and use that in a growler with an airlock?
Any disadvantage to just pitching the yeast into the carboy?
FWIW, I had the same concerns as (I think?) this was the first true mixed ferm I had done with brett. However, I haven't noticed any issues. I also overbuild all my starters to harvest off for a later use and haven't had issues with this one doing that either. And I know plenty of others who do the same. So you should be good to go! But, disclaimer, I only harvest from starters, i.e., pre-pitch, I do not harvest from the fermenter.I pre-ordered this as well, pretty excited to see the funky saison I can create with this. Got the parfait one too, and Chardonnay.
I have seen some people question using a starter for a mixed pitch, due to throwing off the balance of the different yeasts maybe? I will probably make a starter for this one as well though, I don't use a stir plate, just shake as TravelingLight said above.

Has anybody else gotten any sulfur smells from this blend?.... Fermentation took off pretty quickly, and at first it was putting off amazing hoppy smells, but then about 2 days in I could smell a sulfur note.
The sulfur smell ended up going away completely for me. I've used this blend 4 times now, and there's been a bit of sulfur 3 of those times, but it's always dissipated. I think that smell tends to be absorbed by the plastic airlock, though, so I was worried the first time because that's how the airlock smelled right up until bottling. I will say that I had my fermenter in a warmer place than you, and I think that's one of the things that helps with the sulfur. But, you're probably fine. This is by far the most forgiving blend I've ever used.The same thing happened to me. It does seem to be subsiding on day 3 of the sulfury smell, but it's definitely not smelling as great as it did the first couple days.
Interesting. I once pitched the Sour Solera into a batch, and I got so worried at how long it was taking to get started that I pitched the MF Saison blend in there. That will be a year ago in April, so I'll be bottling that in a couple of months.Pitched this and Sour Solera (another BLB blend) last night onto the same lambic 35/65 base wort, around 4 IBUs. The Solera absolutely TOOK OFF within 10 hours (or less, I slept), uff da! Michael's is following hot pursuit.
I also pitched Wyeast Roeselare and Lambic blend on the same wort (it was a big batch). It will be interesting to compare a pre-blended sour "yeast flight" in a couple months! Longer term, I'm looking to do more blending, I have a few fruited sours hanging around that need some acidity balance and brett depth.
