I've been thinking of trying a couple of these, particularly 34/70 and S-189.
For those of you that have used these, could you relate your experiences? I'm
particularly interested in the following:

What styles did you brew?

How were the results? Did you do any blind tastings or enter the beer into
competition?

What temperature did you ferment at?

Did you rehydrate?

How much did you pitch (into what gravity wort)?

I'm an avid lager brewer, and I'd love to get out from under the whole giant
starter thing.

Thanx in advance -- m

Dry Lager Yeast Experiences

G'day TAFKAKS.

I've used the W34/70 for three lagers (Dortmunder x 1, Doppelbock x 2)
and the S-189 twice (both American Premium).  I've had good results with
them in the past, though have never entered them into comps.  OG's
ranged from 1.044 through to 1.085.  Fermentation temps were around
12-14C, using evapourative cooling.  Usually, I make a unhopped 1.030
500mL starter and rehydrate the yeast with that at the beginning of the
boil.  This is enough to get it foaming while not introducing too many
problems to the wort.

Cheers,
Chris from Canberra, Australia

For what is may be worth, the rehydration of the yeast is better served by
pure water. The dired yeast has weak cell walls and the sugar of even 1.030
wort places a great deal of osmotic stress on the yeast. I know it will
still work, but probably because there is a lot of yeast being pitched.
Anyway, try just plain water sometime to see the difference.

Yes, into plain water

No starter, OG 1.036

This fermented very clean and I was happy with the results. Good aeration at
pitching and pitching at 13C worked fine for me.

Short answer : it's a real lager yeast.  S-189 is from (the now defunct)
Huerlimann in Switzerland, and 34/70 is the same strain as one of the
Wyeast Bo-Pils strains.

I've used both and prefer S189 as I find it more predictable.  Very
clean yeast even at low ale temps.

I do rehydrate when I lager (which is rare).  At ale temps I pitch
about 15g per 20 litres.   When lagering, twice that.

If you are an avid lagerer and want to get out of the whole starter
game, then try both and see if either suits your tastebuds.  THat
is really what it comes down to.  They are both "real" lager strains.
With any luck, one of the two will be one that suits yoru tastes
such that you can make it your house yeast.

After bad experiences with both S-23 and 34/70, I sent some S-189 I was
afraid to use to a guy in a newsgroup I'm on.  He recently sent me back
some of the beer he made with it.  It was excellent, much better than
the beers I made with other 2.  I don't think I can say that the beers
wouldn't have been better with one of my favorite liquid lager strains,
but it was worlds better than the other 2 dry lager yeasts I'd tried.

Well, I didn't try the S-189, so my supposition is that it's a better
performing yeast than the other 2.  On those, especially the S-23, I
think my fermemtation temp was too low.  It was actually in the upper
40s-low 50s and by all accounts S-23 performs better at higher than
normal lager temps.

i definitely found 34/70 to be unpredictable.  sometimes i'd get
a wonderfully clean beer out of it and other times some very
odd flavours like bubblegum and so on.  though i suppose if
someone were really determined they probably could figure
out the conditions required to make it predictable.

S189 has never failed me. I use it for the odd lager I do,
and it's my general house yeast for a range of beers including
my Koelsch-eh.  I even used it in a cyser and really like
it there as well.
