Boil 90 minutes
Add hops and Servomyces per schedule, (make sure to open the Servomyces cap).
Stir-in adjuncts at 10 minutes prior to flame-out, (alternatively, stir in adjuncts at flame-out)

Clear wort boil-down notes (Optional Step):
(Optionally) perform a separate boil-down of 1.00 gallon of vorlaufed wort into a syrup using the following steps:
1. Extract 1.0 gallon of wort at the beginning of clear runoff into a 3-5 gallon pot.
2. Boil the wort down until it becomes a dark mahogany brown and is bubbling with large bubbles.
3. Be careful NOT to burn the maltose syrup.
4. The result will be approximately 24-26 ounces of syrup.
5. Re-crash the syrup by adding wort from the ongoing main boil.
6. Pour the dissolved liquid back in to the main boil.

Fermentation Pitch Notes:
Chill wort to 63-64F
Oxygenate chilled wort to 8-10PPM by diffusing pure O2 via .05 micron diffuser for 90-120 seconds.
Pitch decanted yeast starter, adding chilled wort to the yeast flask to clear remaining yeast as necessary.
Ramp fermentation temp (evenly over time) from 63 - 80F over 7 days.
