190 proof carbon dosing...

[Veteran Reefer]

I'm interested in carbon dosing 190 proof grain Alcohol in my 220.6. Has anyone used 95% before and what would my dosage be for my system volume?

I'd just dilute it down to 40% with RODI and use the normal vodka dosing guidelines

I agree. Just follow any normal vodka dosing suggestion and scale it back.

While I think the table is this paper doesn't make sense (not scaling by gallons), it's a fine general guide:
