Went to aerate the batch that I brewed today after pitching the yeast and realized my oxygen tank was kicked. There might have been some minor amounts contributed to the wort but I didn’t see much surface activity when using the aeration stone.
I’m fermenting this one in a bucket so I couldn’t easily shake the hell out of it like I would if it was in a carboy. The transfer from the kettle to the bucket was fairly vigorous with a good amount of glugging and I stirred it up once in the bucket with a spoon as best I could but I’d definitely say the aeration on this one is on the low side.
It’s a 1.059 lager fermenting at 48F pitched with a very healthy starter.
What say you all? Should I just let it ride and see what happens? Or should I head out to Home Depot tomorrow morning before work and grab a new oxygen bottle and give it another dose? If I do that I’ll be adding the oxygen about 12 hours after pitching the yeast which still should be okay, but I’m on the fence if it’s necessary. I’m tempted to let it ride and see what happens.
I don’t think it got much in the way of O2 at all. If it got a minute I’d be perfectly fine with that. I did stir it up pretty well, but I’m pretty sure there isn’t 8 ppm in there.
You can definitely get a nice frothy head on that wort/beer with a mix-stir. If you’re using a bucket you can also sling chit everywhere if you’re not careful. Cheers!!!
I was standing there this morning in my kitchen with a dropper full of olive oil in my hand but I couldn’t bring myself to do it. I’m going to let this one ride. If it flops it flops and I’ll brew another one :-\
If HD is not too much out of the way for you, you may as well pick one up ( I noticed that you posted that yesterday) since you’ll want to get a new bottle anyway.
Recently I started a new bottle of O2, not because I used too much O2, but because I must have left the regulator open. The interesting thing was that with the same amount of bubbling from the wand it took me twice or more as long to get my batch to 8 ppm (ideally I want 10-12 ppm in a lager). I first thought that the DO (dissolved oxygen) meter is broken and I tested it in vigorously shaken wort which did show ~8 ppm. The O2 is a different brand than I had before and just to test this I’m going to pick up a bottle of the brand I used previously to see if that really made the difference. I was utterly surprised since I didn’t plan on having to mess around with oxygenation and repeated DO readings.
