Blending two stouts?

[Greytop]

I have 5 gallons of Yooper's Imperial Oatmeal Stout (8%ABV) and 5 gallons of a Stone Bitter Chocolate Anniversary Imperial Oatmeal Stout (10.25%ABV). Pitched the same yeast to both and they have been in primaries for 3 weeks. I'm planning to bottle three ways. 3 gallons of each one on it's own and 4 gallons blended. Two questions:

1) Anyone have advice about blending stouts?
2) to figure corn sugar for conditioning do I add the ABVs and divide by 2?

Thanks for your help.

1 - avoid oxidation, do a CO2 purge of the receiver and a CO2-push to transfer if you can.

2 - what's ABV have to do with priming sugar? It's all about the quantity of beer and volumes of CO2. Then, temperature and time.
So, four gallons carbed to whatever level you want, plug it into a calculator like this one - or one of the hundred others...

Cheers!
