Did I overprime my bottles?

I poured my priming solution (2/3 cup corn sugar to 16oz water) into my bottling bucket yet only ended up getting 4gal of beer into my bucket because I wanted to avoid trub suck-up.. Do you think I overprimed?

 

Bump

 

This is why I like using weights for priming sugar rather than volumes...but let's assume that 2/3 cup of corn sugar is 133g (according to NorthernBrewer's priming sugar tool).

133g of priming sugar for 5gal of beer at 68F would have given you 2.6 vol CO2. If you change that to 133g of priming sugar for 4gal of beer at 68F, you end up with 3.05 vol CO2. Yes, this is a little high. No, you probably won't experience any bottle bombs as long as your sanitation was on point, even though you are approaching the upper limit of what commercial 12oz bottles can handle in terms of CO2. Just to be safe, I'd put your bottles in some sort of a plastic tote with a locking lid, just in case you do get a bottle bomb or two. This will save you a TON of clean up if that occurs. But I think you'll be fine. I bottle condition all of my beers in plastic totes as a just-in-case regardless.

 

No, it may have a lot of head, but I think that will be ok. If I did that, I would store them safely (in box in garage, or basement, or in a box in a shower stall where if things get explosive, they will be safe.... but otherwise it is high, but probably not worth fretting over. Just be safe..cross your fingers and let us know!
