As an update to the post above, let me share a mistake I made. These images are of one overflow and one that almost overflowed. I filled both of these bottles way too high. Worse, I changed more than one thing about my process at once, and that was a bad idea.
Both of these bottles were brewed last night. Two things were done differently with them. First, I "activated" the yeast by putting it in warm water for 15 minutes before "pitching" it (adding it to the brew bottle). That made the yeast act way more explosively.
Worse, I used raw natural local honey, and the honey can ferment on its own. These two bottles are the first I've used with that honey. The lemon batch is half local and half Costco honey. The larger orange bottle is all local honey. To make things even worse, I added three times the yeast I needed to the orange. Oops!
That will not ruin it, but it of course made things way more powerful. Therefore, I believe the first rule of brewing has been firmly established, and here it is:
Do not drink you previous brew while brewing your next.
I made mistakes, but it's all good. There's so much alcohol already in the bottles that opening them to siphon a little off is not a big deal. Learn from my mistake, and leave more head space regardless of what honey or yeast you're using. I would recommend you do not fill a bottle more than the top ring around the bottle. That is about 4-5 inches below the very top tip of the bottle. In the background you can see a couple orange brews that are filled just past that point.
Now, after cleaning up the mess, I smell like honey and nutmeg. Things could be worse, right? haha
Good information. Fruit addition will do that often, and when you degass. Add a blow off tube to your bung to prevent the mess next time :)
I don't even know what a "blow off tube" is but will find out...
This batch had three packets added too it when it should have only had one. It does not taste good either, but I couldn't bring myself to throwing it away. I still drink it, but it is ROUGH.
