Sloshing wort to aerate

[fozzie14]

Just brewed my first batch, with a Mr. Beer kit. The instructions don't call for sloshing the wort after pitching the yeast to aerate, but after reading about it on many sites, I sloshed for about a minute. Then I read that you need to slosh for several minutes to aerate the wort sufficiently. Should I slosh more? It's been 15 hours since I finished the brew, and active fermentation has not yet begun. Should I/can I slosh more now without negatively affecting the beer?

I wouldn't. It can take up to 3 days to see visible fermentation. The yeast go through a reproductive phase after pitching before you see the beer fermenting. Give it some time.

What's the effect on the beer of aerating vs. not aerating (or not aerating enough)?

 

[unionrdr]

The yeast need o2 for the reproductive phase. I aerate all my beers,regardless of AE or PM. It give sthe yeast a good chance to be healthy imo.

Thanks. I'm a newbie at brewing. What are AE and PM?
