The old rule of thumb that the hundredths place of the original gravity roughly predicts alcohol by volume (e.g., 1.060 wort will ferment into ~6% ABV) doesn't work well for saisons because of their high attenuation. With the start of DC's four months of oppressive heat and humidity arriving soon, I wanted to keep this batch relatively light and refreshing at 1.047. With the wine it still ended up just above 6% ABV.
I fermented it with a starter made from the yeast slurry harvested from the Nu Zulund Saison keg after it kicked (not a textbook maneuver). This is the third use for my house saison blend (a mixture of The Yeast Bay Saison Blend, WLP644 Trois, CB2, and Wyeast Lacto brevis). This turn is heading towards being the funkiest so far. Likely the late harvests are applying selective pressure that favors Brettanomyces. As a side note, White Labs recently renamed/reclassified WLP644 from Brettanomyces bruxellensis var. Trois to Saccharomyces "bruxellensis" Trois. I could care less what genus it is, I still think Trois is a great strain! If anything I hope the strain gains wider use by brewers who do not want to risk introducing Brett to their gear.
Trimbach Gewurztraminer at kegging. I find this to be a much easier, more consistent, and effective way to introduce wine flavors than soaking oak cubes in wine that are in turn added to the beer. Despite the German name, most Gewürztraminer is grown in what is now France. I selected the varietal because it tends to be a more aromatic and fruity/spicy than most European wines. Maison Trimbach is a storied producer which I've posted about before. This 2010 bottle was bright, citrusy and minerally, a nice match for the flavors already in the beer.
Excited to see how it all comes together after keg conditioning!

Sacch Rest - 75 min @ 148F
7 gallons mash water with 2 g of CaCl. 1 gallon of untreated cold sparge water.
Initial mash pH 5.64 at room temperature with 3 oz of acid malt. 1.5 additional ounces plus .5 fl oz of 10% phosphoric acid brought it down to 5.50.
Collected 6 gallons pre-boil at 1.047, diluted with .75 gallons of water to 1.042. Added .5 fl oz of phosphoric acid to the boil.
Whirlpooled 5 minutes, settled for 15 minutes. Wort pH= 5.46. Naturally cooled to 180F. Then added 2 oz each Hallertau Blanc and Hull Melon. Allowed to steep an additional 30 minutes before finishing runoff (down to 145F). Chilled to 68 F, pitched the slurry from the Nu Zulund Saison with 1 L of wort pitched the night before, slow activity.
