i bottled a few to see if it improved and hada taster at the same time. it was also only 10litres in a 5 gallo fv so worried about the air inside.
so i transferred to gallon containers , im preparred to write it off as it didnt go to plan in the brew stage, but see what happens
ive got a 23l recipe waiting but reluctant to start it. i have purchased a grain bag after the first attempt. live and learn
You would have been better off just leaving it, I know there is extra headspace but it would still have been okay and it would have created a blanket.
If you're nervous just do another small batch even a 1 gallon just so you can tighten up your processes and getting used to it.
But whatever size batch I would leave it a minimum 2 weeks in the fermenter before bottling and then leave it to carb before drinking it..
I certainly wouldn't drink it 9 days after I pitched the yeast.
