How do you add them yourself?
The Cryo Hops I used are Ecuanot Cryo hops Alpha 22.8.. 1 bag 1oz. = 2oz of hops. saves money.
The yeast is Imperial Organic A04 BARBARIAN...Temp: 62-70F, 16-21C // Flocculation: Medium // Attenuation: 73-74%
Cryo hops LupuLN2 offers twice the resin content of traditional whole-leaf and hop pellet products, and should be dosed at approximately half the amount by weight.
