I’m getting ready to brew a Brut IPA using Amlyo 300 and am a little confused about the dosage. For those of you adding on the cold side to the FV pre-ferment, what is your effective dosage?
BSG’s website,
Recommended dosage rate in mash is 250 -1200ml/tonne.
Recommended dosage rate in fermentation/maturation is 1-4g/hl.
If I am figuring this out correctly, then for a 7bbl batch (8.21hl), at the high end of 4g/hl, then I would dose with 32.84ml (which is significantly less than if using in the mash which I figured out to be if my mash was 455 lbs grain and ~1432lbs water = 1887 lbs which is .86 tonne = .86*1200 = 1032ml). I digress. I then I found this site that shows,
Dosing Rate:
2-7 g⁄hL (~1-2 ml per 5 gallons)
ÿ2-7 mL⁄hL*
=20-70 ppm
*Assuming the density of water for liquid enzyme
That would be 7bbl=217 gallons/5*2ml (per 5 gallons) = 86.8 ml. That’s significantly more then the 32.84 derived above.
Any feedback for what effective rates others are using pre-ferment would be greatly appreciated.
Thanks!
