BrewBlog: Big Otis
General Information
Method: All Grain

Derived from Saison Exp, number 2.

Franco-Belges pils malt used.  

0.0675 pounds = 1 ounce

Filtered water used this time to remove chlorine.

Preboil gravity: 12.3B (1.048)
Initial gravity: 15B (1.062)
Chilled to 64F, Initial room temperature 58F.
Pitched at 1p on 3-11-13.

2" krausen at 4p, indicated 66F, room at 60F.  Krausen increased to 3" and the indicated temperature 68F at 10p hours.  Carboy relocated to bring the temperature down.

Just starting to blow out at 6a - new tube affixed. Temperature at 66F.  By 10p the krausen had receded enough to go back to a normal airlock.  Temperature at that time was indicated at 64F.  A gravity check was inconclusive, but seemed to be ~11B (1.033).

Temperature now at 60F (6a).  Vents opened to warm the room (currently 58F).  Temperature up to 60F by 10p.  Krausen receding, but that may be due to the lowered temperature.

Indicated temperature of 66F, room at 63F (noon).  Evidence of small blowout.  Replaced airlock.  Gravity at 9B (1.020).

Indicated temp 66F, room at 62F (10p). Gravity measurement reports 8B (1.013), still fermenting.

Indicated temp 66F, room 63F (10p).  Gravity measurement reports 7.5B (1.010).  Hot pad might be used on 3-22 to ensure completion.

Heating pad on '2' - temperature climbed to 70F.

Temperature at 74F indicated and the gravity is down to 7.2B (1.009).

Pad off, temperature falling.  Gravity stable at 1.009.

Transfer to secondary.

Added ~1 ounce of Hallertau leaf.

6-11-13: After far too long, it's bottled.  15x750ml and 12x12oz.
