OG higher than expected. Can I add more yeast?

[wildotterbrew]

I recently purchased a Barley Crusher grain mill and used it for the first time today. While I had anticipated an increase in efficiency over the pre-crushed grain I had been getting from Northern Brewer, I was a bit surprised that it went from ~62% to 79%. As a result, the OG of the beer I brewed today was .014 higher than expected (expected: 1.054/actual: 1.068). This has also resulted in underpitching as I had made a 1L starter, but it should have been 2L according to Mr. Malty.

So my question is this: I pitched the starter late Sunday night. Would it be safe to go get another packet of the yeast from my LHBS Monday morning and pitch it in to account for my unexpectedly high OG?

I don't think that is enough of a difference to worry about adding another pack of yeast. It should be fine.

Probaby not necessary but probably wouldn't hurt it, either.

It's not worth adding more yeast now. The initial pitch would have used up all the O2 in the wort and any new yeast added will not be able to reproduce.

I'll echo the above, it's not worth the trouble now. Your yeast have already been fruitful and multiplied to eat that extra unexpected sugar that you had in the wort. Just let it ride and see what comes of it, worst case is that you have a small bit of off-flavor (fusels or esters) from the yeast reproduction. I wouldn't worry too much though...

Thanks for the input folks. I'll let it ride.
