Notes

Yeast dump from Japanese Rice Lager. Yeast re-use reduces total cost of yeast.

Jalapeños

25 jalapeno peppers crushed into a puree, soaked in Vodka, then added to secondary.

Fermentation
Primary - 11C until gravity is 1.022
Diacetyl Rest - Raise to 17C until gravity is 1.012.

Secondary - reduce to 2C. Harvest the yeast.
Introduce Jalapeños in a bag and test daily for heat.

Remove jalapeños. Attach spunding valve. May get some carbonation.
