Default 565 Saison fermentation

On 7/15 I brewed the Raison d' Saison from Brewing Classic Styles. Mashed at 146 and got an OG of 1.065 (recipe OG 1.060). Pitched a decanted 2L starter of 565 at about 70 and then put it in the swamp bath at 67 and the yeast got down to business. I kept it about 68 for the first two days, then started ramping up the temp a few degrees each day.

Recipe final gravity is 1.008. On day four the bath was about 79–80 and the SG (all temp corrected) was at 1.012. Krausen had fallen, but still lots of airlock activity. The sample tasted fairly dry, slightly fruity and peppery, it was nice. Day seven it was up to 84 and SG at 1.008. Still was some airlock activity The sample tasted perhaps a little boozier, maybe even slightly hot, which I didn't notice on the first sample.

Took a reading today, day eleven and SG is 1.007. Bath has been steady at about 85–86 for several days. The surface of the beer is mostly clear except for some spotting of solid yeast bits that are still hanging out on top. No airlock activity at this point, or at least it's very slow if there is any. The sample tastes similar to the last, slightly hot.

So here are my questions. I know that the flavor of the yeast is mostly imparted in the initial days of fermentation, and this beer was at ~68 for the first few days. Also there was no hotness at all on the first sample at day 4. This is only my 6th brew, but I'm wondering if a) the hotness could be isolated to beer at the top of fermenter and since my thief only takes shallow draws I'm picking up a hotter tasting sample, and b) the yeast will clean up after themselves thereby diminishing the hotness.

I'm also wondering if I should transfer this to a secondary after about 2 weeks in primary, or just bottle after I hit final gravity, or let it go in the primary for about 3–4 weeks then bottle. Also, should I keep it up in the 80s for conditioning/secondary? I've never done secondary before, only 3 and 4 week primaries, which have worked well. This is my lightest color beer yet.

I know a lot of this stuff is personal preference and the primary vs secondary debate is well documented here, but I'm mostly wondering about the hotness (diacetyl?) that wasn't there initially, and if anyone knows anything for me to think about.

Thanks guys.

Gravity is getting low. At this point you could crash cool it...then bottle it with slightly less priming sugar and gamble on the rest of the yeast getting it carbed up...If you are force carbing it then do what you want.

Beligian yeasts are so superbly purposeful with bottle condition. I love them.

Mashing at 146 with a saison yeast, you really might go lower than 1.007. I'd give it more time at high temp, the last few points can take longer, and 12 days definitely isn't enough time for this yeast. I would just leave it in primary for another 2 weeks or so and see where it goes. I don't see any reason to secondary.

I really wouldn't worry about the hotness, you're tasting uncarbonated, warm, still fermenting beer. If it still tastes hot after 3-4 weeks in the bottle, then worry about it, or just let it age more

I'm sorry but I really wouldn't recommend this! Stopping fermentation on a beer that is most likely not done, and putting it in a bottle is a bad, bad idea. It's only at 1.007 and with a saison yeast it could easily go to 1.000 or even lower, and if it's inside a bottle when it does that you've got some serious bottle bombs on your hands. Talk about gambling!

I would leave it in the primary for two more weeks as well. Give it time to clean up, then bottle.

Agree with Chess- make sure the gravity has stopped dropping (100%) and then wait another week to condition/clear. THEN you can package.

Thanks for the great advice. I will just let it do it's thing and give it more time.
