It looks like a great diagram to highlight the complexity of fermentation.Endahttps://www.blogger.com/profile/14993700301275971489noreply@blogger.comtag:blogger.com,1999:blog-6365074056807535758.post-72957022908004510332016-02-14T05:09:58.463-08:002016-02-14T05:09:58.463-08:00Thanks and im Happy to send you one Jay.

I enjoyed the way you touch upon some of the major questions regarding the handling of yeast while addressing the issue that many brewers want a "golden rule" for all things fermentation. Everyone's brew system is different, even if they purchased the same exact equipment, which is something you alluded to but I do not think many brewers understand. Again, great information in this article and I am looking forward to the subsequent ones! I would love a copy of that pdf of the metabolic pathways! Please let me know if this is still feasible. <br /><br />Cheers!<br /><br />JayVT Hokiehttps://www.blogger.com/profile/06060491582777269944noreply@blogger.comtag:blogger.com,1999:blog-6365074056807535758.post-88798755361505872912016-02-12T05:48:34.557-08:002016-02-12T05:48:34.557-08:00Over oxygenating your beer will limit the producti...Over oxygenating your beer will limit the production of esters in the beer. But is that what you want? maybe you want some fuity esters. Maybe you are making a Wheat beer and you want loads of iso-amyl acetate (banana ester). rapid yeast growth produces loads of fusel alcohol which is a precursor to esters in beer. So fermenting to warm or pitching a yeast colony that has loads of growth to do in order to ferment is a sure fire way to increase ester production. So while everyone is looking for hard and fast rules for production... I say seek understanding, not rules.

They are packaged with sterols that the yeast can easily up take. This means less intermediary production of many of the chemicals in the yeast. Although these chemicals tend to only be present during growth, and really produce very few off flavors. The yeast does need some oxygen. I usually use my aquarium pump for about 10-15 minutes. The results are amazing. I have beers dropping from 1.055 to 1.006 (intended), ales finishing cleaner than lagers (but still with slisght ale esters) David Steltinghttps://www.blogger.com/profile/08091919069275585647noreply@blogger.comtag:blogger.com,1999:blog-6365074056807535758.post-71673534658108003672016-02-11T15:14:05.741-08:002016-02-11T15:14:05.741-08:00So I could have gone to be 30 minutes earlier last...So I could have gone to be 30 minutes earlier last night instead of waiting on my aquarium pump to pump joojoo into my wort.
