Kettle Sour:
Mash for 30 minutes. Boil for 10 minutes. Cool wort to 110 degrees F. and lower pH between 4.0 and 4.5. Pitch L.brevis and L.plantarum. Maintain temp for 24 to 72 hours or until pH has reached 3.5. Boil for 90 and follow hop additions as listed above.
Grain Bill:
Belgian pilsner base malt for its diastatic power and Belgian origin.
Munich for its bready/biscuity sweetness.
Caramunich for color, head retention, and additional malt complexity.
Special B for some raisin and dark fruit notes that will pair well with the mulberries.
A very small amount of Carafa III for color but lacking bitterness.
Mash Temp at 148 in order to get the final gravity low enough to fall within the style guidelines.
Just enough bittering hops to reach style guidelines. Not looking for hop character to overpower the sour or malty flavors.
Rack on to about 14lbs of mulberries in a secondary. Age for at least 1 week.
