No, not something I'm given to after six tins of Heinz's fave baked bean...
No, yesterday I thought I would try re-hydrating the yeast in two new kits I now have underway, in addition to the Muntons Conkerwood that perhaps you have read about.
I have followed the instructions for re-hydrating, and added to the well-stirred malt and water... this morning the wife and kids jumped out of their skins when the top blew off the fermenting bins *BANG!* *BANG!*...
So, er, sorry, um... So I put the lids back on, but htey were well bulging soon after, and one I went to prise off and the bastard went *BANG!* in my face - made me jump more than anything...
So I left the lids partly open. What should I do? Before now, when i just sprinkled dry yeast on, this never happened - but then the SG has been dodgy, if the ale drinkable. Do these explosions means that the yeast is working well and alll will be well? How can I cope with expanding air like this? The yeast heads look pretty healthy - some dark brown scum forming over 50% of the wort's head.
Help! i didn't expect this.

Sounds like you have an active fermentaion and nothing to worry about, im just surprised they haven't went bang previously 
. You are going to get lots of CO2 from the fermentation process, if you have a sealed container then you are going tp have the lid blowing off.
You can either fit an airlock which will allow the CO2 to escape or more simply you can crack the lid open ever so slightly which will again let the CO2 escape, hopefully allowing you and your family to have a restful nights sleep .
As i said im surprised your previous brews haven't done the same thing
perhaps previously you haven't sealed the lids as well and this allowed the Co2 to escape slowly. With your improved technique (starters etc) you have an active fermention that is creating CO2 much quicker hence giving you the blow off, or you have sealed the lids better this time. Either way nothing to worry about, just leave the lids cracked open slightly as you have done.

When the beer's fermenting as vigourously as that, there's no need to worry too much about leaving the fermenter lid loose - after all, commercial brewer's don't cover their fermentation vessels at all, but just rely on the yeast head to protect the brew.
I would just rest the lid on top for now, and maybe by tomorrow or the day after it'll be safe to put it on properly.
EDIT: Delboy, you type faster than me!

Re: gas
Is installing these just a matter of drilling a hole in the lid and then putting the grommet into the hole with the airlock?EYE JAY wrote:do you have a airlock for your fermenter?
if not you can buy a grommet and airlock and install them.
gas will be safely released without comprimsing your wort.

yes its as simple as that,your local HBS will advise you on what drill bit to use or even like mine drill the hole for youdavidson wrote:Is installing these just a matter of drilling a hole in the lid and then putting the grommet into the hole with the airlock?EYE JAY wrote:do you have a airlock for your fermenter?

Thanks guys and gals, I feel better now, and will leave the lids on these two slightly ajar for 12 hours and then put the lids on fully.
fwiw, I'm sure this has everything to do with the way I have pitched the yeast, and will wait until complete to assess and judge whether I should re-hydrate or not - it all seemed so simple to merley sprinkle dry yeast on top, but this re-hydrating is really spectactular! Much more like wot I thought it would be like.
Cheers peeps!

Just wondering what you mean by ajar?. You shouldn't have to have the wort exposed to the air at all (ie visible), just take the lids off and then replace them on again without snapping them down (as jim said), no real reason to do anything else for the rest of the ferment, remeber if you snap them down completely they will be airtight and you'll get a the lids blowing off again.
Sorry if this seems like im patronising you and stating the obvious just trying to make sure we are all singing off the same hymn sheet

No, I meant just cracking the lid to release whatever pressure and not pressing the thing back down again.
Does this sound like it wil protect the work enough? I wouldn't remove the lid, even partially or fully.

Don't think you'll have any probs now, congrats on getting a good healthy fermentation BTW.

I never snap the lid shut, and don't ferment under airlock - after all yeast needs oxygen to survive and do its job.
The wort is only really vulnerable during the early stages of fermentation - snap on the lid, then crack a small bit open to allow the CO2 to escape. After a few days, I just drop the lid onto the FV.
