Yeast and Fermentation / Re: High alcohol tolerant yeast
« on: April 25, 2017, 09:04:29 AM »
I think 2 packs of US-05 will get you there. But for beers in the 10%+ range, I prefer to start with a beer in the 1.060 range, then rack onto the yeast cake for the big boy. Having a fresh, big pitch that has develeloped a bit of alcohol tolerance will rip through even the biggest beer pretty reliably.
   Thanks.
   I'm still working on getting my head around what seems to be a contradiction. We are always counseled to "pitch plenty of yeast" for big beers, because what you pitch is only good for 4 or 5 replications/generations, but people regularly use and re-use what essentially is recycled yeast for beer after beer.

the number of generations you can go with a pitch of yeast is dependent on your sanitation and storage methods, and your tolerance for genetic drift. 4-5 repitches is generally pretty safe, assuming good sanitation.

The concern with pitching rates is that you want to control the amount of reproduction the yeast do in your beer because they produce many of their flavor compounds during that reproductive phase. This is all very backyard science-y and not at all really accurate to what's going on but the effect is at least repeatable.

honestly, most yeast strains will have no problem with 12%. You do have to be careful to treat them well and pitch enough highly active cells to start. I've taken Dry English Ale (WLP007) up north of 12% on several occasions with a wort mashed low (148) and some (10%) simple sugar added.

US-05 will have no problem either.

Make sure to warm it up a bit towards the end, especially if you use a British strain. Give it some yeast nutrient in the boil.

if using liquid yeast, make a 1 quart Shaken-Not-Stirred starter when your mashing and it should be at high Krausen when you are ready to pitch.

if using dry, use two packets.

if you are adding simple sugar, which I suggest, add it after the first three days of fermentation, this keeps the gravity a bit lower to start so the yeast have time to build a solid population.

I really like Belle Saison actually. it's a crisp, lemony finisher. and is a beast.

Unless your thermo is way off I find it hard to believe it's the mash temp causing the problem. I notice attenuation differences when mashing at different temps but they are not huge.

My first thought with unexpectedly high attenuation is contamination with a more attenuative yeast and/or bacteria.

I suppose there may also be variation in the Malt composition. did you use the same maltsters products across batches?

I just tasted an Altish ale I brewed with local Peterson's Quality Malt (Combined with some Best munich because the LHBS ran out of the PQM 'Munich' part way through my order) and it's tasty. The yeast really seemed to like it as well. WLP029 ripped through 1.060 to 1.008 in 7 days.

General Homebrew Discussion / Re: Maple Barrel

The flavor of maple would be lost. it takes a lot of maple to come through at all. I would soak some wood in bourbon, or use a bourbon barrel stave if that's what you've got, and also add maple.

I add ~ 1-2 quarts of the darkest strongest flavored maple you can get in 5 gallons of beer and get a hint of maple flavor. I add the maple after the height of primary fermentation. the yeast are going to ferment those sugars out, but if you wait till they are not going crazy you can retain some of the aroma.

I've used local malt a few times. When the local guy first started up he had some QC issues and I felt like the malt had a lot of draff still in it. Lately it's been better. There is a distinctive character to the beer. I wouldn't use it to brew an authentic german lager because it's not authentic german malt, but for a Vermont beer it's great.

I think it's worth remembering that there are times when consistency comes at a cost. If you can't always ensure tip top perfection, you may be better off, if you are working on a large scale, aiming for consistently 95% perfection.

Gotcha.   What's the issue with hitting slightly lower and just increasing the temp?

if you've got the ability to manipulate the mash temp with a recirc then there isn't really any danger of hitting a slightly too low strike temp.

My comment was more to remove stress about overshooting.

Basic structure here:
~145-149 - a lighter body, greater attenuation, longer mash time for full conversion
~150-155 - Medium body, medium attenuation, medium mash time for full conversion
~156-162 - Greater body, lower attenuation, shorter mash time for full conversion

however, I generally concern myself with three mash temps

~148 for light bodied, or very high gravity beers
~155 for medium bodied, crisp but malty medium gravity beers
~162 for extra body in low gravity beers or straight up thickness in bigger beers.

and this is all very subtle and variable.

And I've found that malt has so much diastatic power these days that temp matters a lot less than it used to.  I've mashed the same recipe at 153 and 165 and gotten identical results.

I do tend to use a lot of munich

Too high is pretty high.

I've mashed beers at 162 and even as high as 164 and still got good conversion. if you are aiming for 150, and you hit 155 you MIGHT notice a slight difference in body.

finally brewed the batch I intended to get to on sunday.

Of course instead of Sunday's beautiful sunny weather, I got 38 and rainy, occasionally torrential. The price we pay I guess.

The LHBS only had one packet of 34/70 so I added a packet of S189 as well.

Brewed 10 gallons of wort, pitched 5 with the lager blend for an amber kellerbier and the other 5 with german ale for an Altish

next time pop it in the fridge for a few hours first. the cold will help the beer absorb more of the co2 that is in the headspace and make it less foamy and a bit more sparkly.

Gonna brew my Marzen recipe, but drink it young and call it Kellerbier

Oops, was looking at "uncorrected" gravity.  It's at 1.010.  I didn't notice any diacetyl.

Sounds like you added enough yeast. how does it taste otherwise?

1.018 seems really quite high for an FG. perhaps a typo and you meant 1.008?

D-rest won't work well if the yeast are dormant. does it have Diacetyl? if not then you don't need one. if it does, you can get another big starter cranking and dump it in to the batch to clear it up.

6 days seem pretty quick but the ramp up method does seem to turn lagers around pretty quick.
