Title: oops... starter woes.
Post by: smithy222 on July 17, 2010, 03:50:19 AM
So I make my starters in a 1/2 gallon growler. After sanitizing the growler I was using the sanitizer inside to pour over the peice of tinfoil I cover it with. I would pour a little on, let it sit a few, then pour a little more on... you get the idea. Anyways, once my wort was cooled I ripped open my yeast smack pack and poured it into the growler. Only then did I realize I just poured the yeast over one or two ounces of Star San solution still in the bottom of the growler. I then quickly poured in the wort to dilute the sloution as quickly as I could (about 1 liter). So... what can I expect? Would Star San kill all my yeasites that quick? If they live will I get a bad taste?

Keep an eye on it, star san does not kill everything on contact that is why they recommend atleast 2 minutes of contact time. You did not kill all of your yeast.

Agreed, they certainly won't *all* be dead, but I wouldn't assume you'll get anywhere near what you were expecting either. I would take what you get from the starter and pitch it into another 1 L of wort, just to play it safe.

FYI The "official" kill time is 2 minutes but I have heard the manufacturer claim that it is actually closer to 30 seconds.

Absolutly zero krausen this morning. I think I will make another liter of wort for those buggers and see where that gets me.

When I talked to him he claimed a 9log kill ratio in 30 seconds, but had to say 2 minutes to legally call it a sanitizer.
that is 1 our of 1,000,000,000 bugs left alive after 30 seconds.

I do see co2 bubbles coming out of the solution. Could it be that it is fermenting but the Star San is killing any krausen that would be forming?
