About 3 weeks ago I brewed a Saison. AG, nailed all my temps and numbers, SG of 1062. I made a 1800 ml starter for some old (6/29/11) Wyeast 3724 and got decent growth. Pitched and had great krausen and activity within 8 hours. So, little lag time and visible activity. I have used much older yeast with great results and saw nothing that caused me concern. I started at 65°F and slowly ramped to about 78° over the course of next 10 days. I use a wine fridge w/ a digital temp controller to control fermentation temps. The 60w bulb I was using to keep temps up ended up overworking the fridge and came home to a fridge giving an error message and temps around 85, beer temps at about 81-82. Not too crazy. Got fridge reset and temps back under control. Figured after a week and a half I was past the majority of ester production. By morning I was back to around 77-78. Kept chugging a way, maintaining 75-76. Today was day 21 of active fermentation, though it appeared to be slowing down. Krausen fell around day 16-17. Nothing but little bubbles from CO2 production and yeast rafts on the surface. I was starting to worry about an infection because of the length of primary fermentation, but no evidence on visual inspection. I brew mostly Belgian style ales and have had fermentations remain active for 2-3 weeks before, so I wasn't too worried. I made a starter for some Brett I harvested from a bottle of Crooked Stave that I planned to add to a couple gallons of this Saison as an experiment. Took a sample (expecting at least 1010 & probably closer to 1006) and was surprised to get a sweet 1030. I am not sure why the gravity is still so high. I swirled the carboy to rouse the yeast and am bringing temps back up to around 80 to keep it working. Just wondering if anyone has had similar experiences with this yeast and has any suggestions. I am used to babying Belgian yeasts to maximize attenuation, but I have never gone 3 weeks to only get halfway to my expected FG. I can still pitch the Brett to finish off the whole batch, but would really like to compare the Brett and non-Brett versions. For now I plan to RDWHAHB, but I'd like to figure out what is up. Whatcha think?
