Recipe: Carol "Lambic" 2.0 (Where the Wild Things Are)

As I sip on my “Lambic” from last year, which I am very pleased with, I am very anxious to brew another one.  This time I will use the same yeast culture from the last one as I saved the entire cake from the last brew in a gallon jar in the fridge.  This year I am going to go with a grist that is much more traditional, 65% Pils, 35% Raw Wheat, mashed @ 158*F.  Last year I had some character malts like Vienna and CaraVienne which are not traditional and I’m not sure they added any needed complexity other than color.  I also had a flavor hop addition which is pointless in a beer aged for a year, coriander was the same.  I added some cake flour last time for a little more dextrins to chew on since my mash temp was fairly low. 

I could always do a turbid mash, but why?  I could also do a cereal mash, but why?  These things are traditional, but do they add anything to the final product that won’t be there (or at least drastically noticed) in the final product?  My first Lambic is quite nice and it was mashed at 152*F, and hit 1.006 in 3 weeks.  The 158*F mash should leave a larger amount of dextrins in the wort for the bacteria and Brett to munch on, and the large pitch of yeast cake should ensure a healthy amount of bugs and Brett as well as autolized yeast for them to eat as well.  That combined with an overnight open cooling in the garage where all my wild stuff is going (which I already fermented a ½ gallon of left over Brown Ale spontaneously in there), and some more dregs from commercial and homebrewed sours should ensure a good, big, powerful, and characterful fermentation from the onset, avoiding some of the enteric bacteria that are not desired.  Add in a 3 hour boil, and aged hops, we are looking at a great start to a second Lambic for next year.

Brew day started off difficult.  I overshot my strike temp and hit a mash temp of 165*F.  After adding cold water I ended up at 148*F.  Added boiling water to get up to 152*F, then added more boiling water to get it up to 157*F, and rested for 45 minutes.  Wasn’t planning on doing a step mash, but oh well.  After collecting 10 gallons of wort I drained the last of the runnings into a separate kettle and boiled it down to about 800ml of 1.080 wort.  I added this to the beer and drew off 1200ml of 1.040 wort from the boil and cooled it to make a starter to my dregs while the wort cooled over night.  I added the dregs from a Hannsens Oude Gueuze to the starter only for a fruit fly to get into it and render it useless.  After a 3 hour boil, I had to move the keggle into the garage for the overnight chilling, and of course, while carrying the 15.5 gallon beast of a brewpot with a scorching hot bottom, I hit my leg with it and burned it quite nicely, luckily I only did it once and got the wort to the garage without spilling any or hurting myself anymore.  I covered it in a large sheer curtain sack that I synched down on the sides, hoping that the Fruit Flies don’t get into there like the starter.  After about 28 hours at ambient temp I racked 5.25 gallons of the wort into the 6 gallon carboy with the yeast cake, oak, and dregs.
