Default How do you aerate?

Do you go extra measures to aerate your wort after pitching your (liquid) yeast? Or do you just shake shake shake? Do you think it is worth aerating with O2? Have you ever had fermentation related problems from not aerating properly or the opposite (great fermentation without bothering to aerate?)

I use an oxygen kit from williams brewing. If I run out of O2 I use a whisk. I noticed a more vigorous fermentation once I started using the O2.

Another vote for the Williams oxygen system, my fermentations have been better since I started using it. I feel like my lag time is consistently under 12 hours now and I think it has improved my beer.

I have had fermentations where I really got lazy and didn't think that I did a good job aerating and I didn't really notice a difference in lag time or end product, to be perfectly honest.

That being said, I've taken to aerating by dumping my wort between two sanitized buckets lately and I really like how that works.

I put a pin hole in the tube (with a hot paper clip) from my kettle valve. The venturi effect leaves a nice thick head in the carboy.

So you just put one small hole in your transfer tubing and that is enough? It seems like a good idea and i might try this. i used to use an IC so once it was cooled down i just would dump it all in the fermenter which i thought gave plenty of oxygen. i just built a CFC so now i won't be doing any dumping (unless id fill on bucket then dump into another). but this seems more simple if it really works

I like this idea, I would assume you have not had any issue with infection.

I use a 20 cf O2 cylinder, regulator and a stone.

I'm going to try a paint stirrer attachment on my drill this time. From what I've read, it should take 2 minutes to get the O2 level up to 10ppm at 50 f. Hope it works.

I just strain into a bottling bucket and then transfer to carboy. I also rock the tube back and forth as it pours into my carboy.
