I'll chime in here. I'm currently using Omega German Lager 1 DKO. After getting a tad familiar with WLP830 and W34/70 I have to say this is the best variant of the strain. It's just clean throughout the full fermentation and I find it a good bit crisper in my home brewery than the other variants. Now I have not used ALDC enzyme with the other versions, but, I have some on hand and intend on messing around with it to see how the results compare. I will say that the DKO version is flat out cleaner when fermented low compared to the other two strains. When I tried fermenting anywhere between 50f-55f I always got a weird acetylaldehyde/sulfuric twang that I don't get when fermenting the same strains 60F and warmer. This strain also repitches well which is not something I can say for W34/70 in dried form. I've also run into inconsistent results with the dry form of the strain. WLP830 also repitches very well.
Another difference I noticed is that the new screw top pack of WLP830, pitched into a 2L 1.040 starter on the stir plate, takes off fast from the initial pitch. I had activity in fermenter in less than 5 hours. The Omega German Lager 1 DKO variant is a touch slower on the initial pitch. However, with a repitch it stacks up admirably with the WLP830 lag time. Both variants ferment extremely well under pressure. My schedule so far has been to set the spunding valve to 15psi 54F for the first 24 hours, let the pressure build naturally, then step up 4F every 24 hours until the temp hits 66F and just let it ride. With this setup I'm typically cold crashing by day 6-7 and packaging in less than 2 weeks from the initial pitch. The Omega DKO strain did take 9 days on the initial pitch to complete fermentation but now it's right up there with WLP830 in being done at 6-7 days.
I initially was a bit standoffish on using this strain due to yeast companies pushing novelty strains. This one actually stacks right up to it's marketing. Omega did a great job developing this strain!
