HELP! Have I over primed my bottes? will they explode?

Post #1 made 11 years ago

Hi guys,

I bottled my first BIAB today and batch primed with Dextrose. So I used the BIABacus which said use 2.7g per 500ml bottle (2.5Vol). which I worked out to be 24.3g as my batch size is one UK Gallon (9 bottles) so 9x2.7=24.3g. Ok.

So just out of curiosity I had a look on the northern brewer priming calculator (after I had bottled) and it suggests less than half of that 5.44g. :nup:

Also I only managed 8.5 bottles as I had a little trouble with my syphon.

I Feer I'v made a huge mistake somewhere, do I need to abandon my brew before explosions start happening?

Please reply asap, Im scared! :pray:

Cheers!

Balli.

Panic over Balli :argh:

It's also possible that your beer will be less carbed than you expect using those calculators. It has been mentioned on here previously that they may not be that accurate. I would be interested to know if this is the case for you.

balli1990,

Just to be sure. I have put a case of "questionable" beer in a large garbage bag to prevent a big clean up "just in case"? It never happened but the beer was still a gusher. Chill before using is good advice! So is, "open outside" or "over a sink" until you know what's "up"??? :idiot:

Thank you for the replies guys I feel rather :headhit:

Looking at the northern brewer calculator it suggests (28.75g) more than what I primed so I think it will be fine. :cool:

Using swing top's so I cant loosen the tops like PET unfortunately.

Ill definitely chill before opening though one or two of my bottles are a little full Im not to handy even with an auto syphon.

I like the bin bag idea I think I will employ this as im lazy and dont want to have to deal with an unlikely beer explosion.

Thank you all :)

Just a quick question :)

What would you guys advise is the correct amount of head room for glass bottles?
Is it even that important? Or is there more danger of bombs/gushers when they are too full?

Cheers

balli1990,

I am not sure why we leave a inch of space headroom? :think: But I leave the exact amount using a bottling wand.

Bob, the headspace is IMPORTANT.

The beer volume increases as the temperature increases, so the headspace decreases, and the Bottle pressure increases.

If the Bottle has little/none headspace, the bottles becomce "Beer Bombs" and the temperatures increase.

The space from those spring bottling wands is the best headspace!!

I have made Beer bombs with less than 0.50"/12mm headspace!!!
