Dear Mr. Wanker,

I want to thank you for your avid participation in the AHA Forum. I hope it has been a learning and inspirational experience. We appreciate your active engagement and hope you will continue to join us ongoing. By the way, using foil to cap your yeast starters is recommended. Please don't hesitate to contact us for all of your wanking needs at your convenience.

Cheers

Well, the AHA removed the link to the video from our site as I requested.  I agree the production values were good, but speaking as someone who's spent over 30 years in the production biz, if the content isn't accurate, all you're left with is a good looking nothing.

Picture the O2 molecules as salmon trying to swim upstream against the current in a river of CO2.

You might be right to some extent, but the flow is pretty slow and there is likely to be O2 molecules with sufficient energy to overcome the current, especially when the flow is spread out over the mouth of the flask instead of concentrated in the outlet of an airlock.  I don't have any data to support this though, maybe someone else does.

I was talking to Dana, aka the man with the goggles, the other day about the video.  It was not their intent to recommend making a starter for dry yeast, only to demonstrate how one goes about making a starter.  Their choose of dry yeast was purely economics,  $3 for dry and $8 for liquid.  They felt Home Brewers advanced enough to consider making starters would know that dry yeast doesn't require, nor should it utilize, a starter.

Alas, they made assumptions and that is never a good thing but their intent was good and I still like the video.  I wouldn't hesitate to recommend it but I would qualify it with "Use liquid yeast only, dry doesn't need a starter" and "Use foil or foam, not an air lock, your yeast will be happier"

The genuine desire to help newbie brewers was clearly apparent in the video.  Is there opportunity to remake the video? (Assuming Dana and crew feel up to it)  Perhaps the video could be broken into two portions; reconstituting dry yeast and making a starter for liquid yeast.  As far as the next version goes; Bluesman made a good point, sanitizing before a boil isn't necessary.  Skip the airlock.  Technical stuff - once the boil is started you can loosely place the foil over the mouth of the flask, as the steam rises it will sanitize the foil as well.  When the starter is ready for yeast, it's not a bad habit to hold the foil above the mouth of the flask.  This accomplishes two things, it shields the mouth of the flask and it keeps you from setting the foil on a non sanitized surface.  Good luck with the second version.  cheers, j
