Any suggestions on using fresh raspberries with this recipe?
Go light. The beer taste is pretty delicate. Easily overpowered by fruit like that. That said, I'm not big into brewing with fruit or additives so no idea how much to add or when. Sorry! Maybe someone else can chime in...

I've only brewed this one once, but didn't experience the 'stall'.
See the notes section of the recipe as well for more info on this - I think the trick is in my words here:
Pitch yeast and ferment at 66F for the first 3 days then allow the temperature to rise to 85-90F until complete (raise a few degrees per day). Do not allow temperature to drop.
If you do have issues:
If yeast seems to be stalling, do not be afraid to raise temperature as high as 95F to ensure proper attenuation as this yeast works well at higher temperatures. If the temperature is not raised this way the strain tends to stall out in fermentation at the 75% mark and then sometimes restart as long as two weeks later. Some brewers have had to resort to champagne yeast to finish.

Thanks Kal - I'm planning on using that fermentation schedule.
Debating on the "use foil" part of the link I posted. Seems reasonable considering this person's experience with saisons but it's summer and summer means flying critters. I'm not completely convinced that putting foil over the top when it's fermenting will give it enough room to "burp" out the CO2 without gnats getting into the wort/beer.

I have the fly problem in my boil kettle, the other day I fished out 10, for some reason flies and yellow jackets love boiling wort _________________ "Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world."

Flies or other bugs in the boil kettle = no big deal as they get boiled.
Flies or other bugs in the fermenter = much bigger deal as they can infect the beer, especially if it's near the start of fermentation and the alcohol level is low.

Hi York!
Valid question. I didn't do anything special about cleaning, because from what I can tell at the time I brewed this beer there was no mention of Saccharomyces cerevisiae var. diastaticus being a possibility in their WLP565 strain. Fast forward a few months and White Labs was sued by Tired Hands brewing and the following text showed up on a bunch of their yeast pages:
Quote:
**This strain has been genetically typed in our lab using polymerase chain reaction (PCR). Through this genetic testing, we have determined WLP565 Belgian Saison I Yeast to contain the STA1 gene (glucoamylase), a potential indicator of Saccharomyces cerevisiae var. diastaticus. Brewers yeast are natural hybrids, which make it possible for certain strains to display elements of the STA1 gene. These strains have the ability to utilize some dextrins (unfermentable sugars), resulting in higher levels of attenuation than what is considered typical.
At White Labs, we do everything possible to detect for undesired organisms within our process and cultures. The strains we carry with known Saccharomyces cerevisiae var. diastaticus genetics have been researched and validated to perform without excessive over-attenuating, which is possible through our nearly 25 years of experience paired with internal and external fermentation data.**
My take: They're not saying the strain has Saccharomyces cerevisiae var. diastaticus, but that it *may*. A CYA move most likely on the part of White Labs.
I've made dozens of batches since this one that attenuated normally so that's good (for those that aren't aware, the presence of Saccharomyces cerevisiae var. diastaticus will usually have your beer attenuate considerably lower than you'd expect as it eats through just about anything).
I'd clean/sanitize anything that comes in contact with the yeast very thoroughly, a physical cleaning (not just soak).

Thanks Kal for the thorough response.
I've read where it is causing headaches for some pro brewers. They're sending bottle bombs out to market thought to be fully attenuated. They say 1 cell of the variant is all it takes to start fermentation of any remaining dextrins in finished beer. Someone posted that it will even ferment old socks and underwear
Others have posted they use it frequently with no cross contamination.
Wyeast indicates it is present in their Belgian Saison:
STRAIN: 3724
BELGIAN SAISON ™
Species: Saccharomyces cerevisiae var. diastaticus
This strain is the classic farmhouse ale yeast. A traditional yeast that is spicy with complex aromatics, including bubble gum. It is very tart and dry on the palate with a mild fruitiness. Expect a crisp, mildly acidic finish that will benefit from elevated fermentation temperatures. This strain is notorious for a rapid and vigorous start to fermentation, only to stick around 1.035 S.G. Fermentation will finish, given time and warm temperatures. Warm fermentation temperatures, at least 90°F (32°C), or the use of a secondary strain can accelerate attenuation.
This Wyeast yeast strain has been classified as Saccharomyces cerevisiae var. diastaticus using rapid PCR analysis. This strain carries the STA1 gene, which is the “signature” gene of Saccharomyces cerevisiae var. diastaticus and will be found in all diastaticus strains.
What to do...? I just retubed the brewery and Keezer this year. I have a bottle of Saison Dupont to sip tonight and ponder.

The recipe on the website has changed since I first brewed this. More Belgian pilsner malt and another packet of yeast. Anyone have any idea why? I felt it was perfect the way it was. And of course I brewed this one yesterday and my readings were off all over the place. Now granted, I had two wisdom teeth removed on Tuesday, so I am sure I must have missed something in the process.

Hi!
Sorry about that - had a typo with the pils malt amount (should be 18.25 lbs not 24.5 lbs) when I moved the recipe to the new website. It's now been corrected. Thanks for noticing! The 80% was correct however.
I popped the recipe into my recommended yeast starter calculator and it gave me 701B cells so 7 packs of yeast is correct (assuming they were manufactured within a few days). Previously it did say 6, and that would "work" too. I recommend using a single pack and making a starter as per the YEAST STARTER guide as linked to from the recipe. Much cheaper.
