This Ink will give you some good info for recipe formulation.

http://aussiehomebrewer.com/topic/40156 ... ark-lager/

Some of the brewers that are commenting in that thread are well respected in Australia within brewing circles.

Has anyone experience with the Urquell Lager (Wyeast Labs #2001)? I've finally brewed a Dark Czech Lager on August 25th (Wanted: Czech Dark Lager ).

After almost two weeks in primary it's at 1.043, with an original gravity of 1.055. Will give it another two weeks, but it seems to be quite slow... :)

I've only used it once, but that sounds like it didn't get a good start. If it's been 2 weeks already, I'd think about repitching a big, healthy pitch again now. Did you do a starter the first time? At what temp are you fermenting?

P.S I moved this back over to your Dark Csech Lager post

I use it qite a lot, infact it is my "go to" lager yeast for many styles.

I make a starter of the size recommended for each brew, I add oxygen via a stone and my ferment is usually down to under 1.016 or 7 within 7 days.
I raise the temp if I am home for a D rest but in most cases I just leave it the 2 weeks at usually 14 deg and it finishes clean and on target.

I think you may have underpitched or the wort was not oxygenated.

I've created a starter based on http://yeastcalculator.com. It's fermenting at 11°C at the moment. Since I don't have a oxygen system at the moment, that might be the reason.
At the moment I've only a Bohemian Lager Yeast (#2124) in stock, do you think it's a problem? Else I would need to order the Urquell 2001 today.

Is there anything I need to consider when re-pitiching a new starter?

11C should be right in the middle of the range. You might think of using the Tasty (Mike McDole) lager profile when you repitch. You will gradually raise the temp as it ferments and end up at diacetyl rest temp.

2124 should be fine. You'll have a slightly different ester profile, but it should be pretty clean. Since you've fermented a bit already, it's probably best not to try to oxygenate by agitating your fermenter. It's probably a good idea to add some yeast nutrient - something like Wyeast Nutrient.

Thanks Nesto! That's my way forward. Will keep you posted how it turns out, once back from Paris.
