Cant speak to 002 but 001 you should have no issues based upon my experience.
Theoretically, yes; however, there are other factors such strain robustness and storage temperature.
So Irish ale and English ale yeast in pure pitch are out in my lhbs now. Want to plan brews with these soon pitching one pouch. Just picked up Jul 21 production of wlp001 to run an IPA with it next week. Likely push a little higher OG with this one.
I’ve got two five gallon batches of WLP 004 going in an Ordinary Bitter (1.040 O.G.). I figured the lower the better for OG. Then try repitching into a larger beer. The yeast certainly looked very healthy and were one month old. Let us know how it goes and I will do the same.
Brewing an all challenger 1.051OG, 50ibu English pale ale this weekend or next with one pouch wlp002 pure pitch.
Update- The WLP001 beers have come out great. No flaws and all as expected.
The WLP002 was 1.051 OG and finished 1.010. It was UK Challenger PA. The pure pitch was 4 weeks old when pitched directly into wort. Absolutely a fantastic representation of English Pale Ale- 8C.
Looking forward to additional strains and brews with pure pitch.
I think increased purity and better packaging are both pluses. Seriously I was surprised to hear people say they prefered the preforms… I always hated shaking the crap out of them… Then dealing with the potential volcano when you try and remove the lid. If I can just rip the top off this new packaging and just pour and push the yeast out like toothpaste into my starter I’ll be a happy camper.
agreed. shaking the crap out of a vial, especially the chunky strains was annoying. its more like wyeast now and pours out nicely.
the one pure pitch wlp002 made one fantastic UK Challenger PA. 1.052 OG and finished at 1.008. cant wait to get it carbonated, as sample is really nice already.
EDIT: recipe was 95% maris, 3% 80L crystal, 2% 165L extra dark crystal. 40IBU all challenger. mashed 149F 5.4PH
For the record - I had great success with the 004 Pure Pitch in 5 gallons of ordinary bitter at 1.041. Finished quickly (as expected) and I have repitched it into an Irish Red 10 gallon batch at 1.055. Also , I have a side by side 5 gallon Ordinary Bitter with one using 002 Pure Pitch and one using S-33 as a taste comparison. The 002 took off slightly faster than the rehydrated S-33, but only by a few hours. So far, Pure Pitch seems to be a highly viable product (pun intended) at least to this brewer.
agreed- i’ve seen all i need to for wlp001-002 with great results. looking forward to more strains to hit the shelves- especially my favorite wlp090.
Coming late to this party. I just landed a Pure Pitch WLP001, Production July 28th, so almost 2 months old. I’m wondering if a direct pitch in a 1.060 2.5 gallon batch would be sufficient with this date. Judging by the results reported, I’m inclined to give it a try. Tubes of this age would have had me making almost a 1 liter starter. Worth a try for us half-batchers.
more and more pure pitch showing up at LHBS. they have kolsch wlp029 and belgian wit wlp400 now.
I got a pouch of wlp400 manufactured Nov 12. I will be pitching this direct without starter into a wit this week.
So I did end up doing a direct pitch of my pure pitch 001. Lag time was about 18 hours. Pitched into 2.5 gallons of a 1.055 pale ale which finished with an FG of 1.010. Entered that one into a competition and took home my first ever 1st place. Definitely a successful test. 
Congrats on the 1st place
think layer of krausen at 10am- +17 hrs from pitch. pitched at 64F, now at target 66F.
i had forgotten how slow wlp400 is. went strong with 3-4 blow offs in week 1 at 66-67F. Now at 70F and still active and ripping away on those sugars.
Yeah. With that top-cropper, you almost have to gently swirl the fermenter to get that yeast back down into the wort to continue fermenting away sometimes. Great character though.
Is the yeast in WL purepitch is different from that in the tubes? I seem to pick up that it’s less likely to be contaminated than the tubes. Is there something else? The WL website does not contain any information that I could find.
Waiting for the blind side by side test
