I always brew with a friend splitting a 5 gallon batch.

I'm ready to move into kegging (have an old freezer ready to go) but my brewing partner is not. So he will still need to fill bottles.

I have a few questions on the best practices for doing this.

1.) Do I get 2.5 or 3 gallon kegs? Or go with 5 gallon kegs?

2.) If 5 gallon kegs are filled half way, am I using significantly more CO2 to carbonate?

3.) Would it be best to keg all 5 gallons and fill bottles from the keg or keg half and bottle the other half with priming sugar?

Thanks!

This will probably end up as a personal preference...
Since 2 1/2 gal and 5 gal kegs are about the same cost going with the 5 and using more gas may be the way to go. You would need a beer gun for bottling carbonated beer from the keg. I got a deal on 2 1/2 gal kegs and it works well for me since I brew 10 gal batches. 5 gal into the 6th barrel, 2 1/2 into the mini and bottle a case....

If there is sufficient room for five gallon kegs, I'd go with those for the same reasons already stated, cost being the biggest.

You'll use a bit more than half the gas carbonating and dispensing versus a full five gallon batch, the small difference being the gas used to push (whether a full 5 or half that to start, you end up with an empty keg filled with CO2, but you only pushed a half keg of beer).

I'd carbonate in the keg then beer gun the bottles...

Cheers!
