Subject: Yeast identification problem Safale US-05 and S-04
I'm making two batches of cider with two different yeasts. Unfortunately, after
starting the yeasts disolving in water, they got moved, and I don't know which
is which. One batch was sort of a tanish cream color, the other, closed to a
paper bag brown. Can anyone help me figure out which is which?

Safale
US-05
S-04

In cider of unknown composition and just a slight color difference I
doubt if you or anyone could tell by sight. You may find someone that
can tell by taste and/or smell.
Good luck.

The color described was the yeast and foam after adding to water, before I put
it into the cider.

I went to Google images and searched for "safale s-04"
and then "safale us-05".  Most pictures were of the
packages, but there were some useful pictures.
Some folks were washing yeast, and so had small
jars with cultures.  There were a couple of petri
dish pics.  

Overall, it seemed that s-04 was darker than us-05.

OK I see that Bart helped. You could call the dark one S04 but how
confident would you be. If there is a noticeable difference in taste or
smell maybe someone can help when it's done.

Excellent idea for finding an answer. I think I have to agree with you. Thanks.

Other opinions would still be appreciated.

I would ferment them both out.  My experience with both has been that
the S-04 takes a LOT longer to drop out of suspension.  The US-05
finishes up and drops to the bottom within a day or two.  The S-04 stays
clumped up and floating around for maybe TWO WEEKS.  Just my
observations...maybe someone else can comment on this aspect of the two
yeasts.

I'll be keeping an eye on that. Thanks.
