As I checked out the new URL for dmtaylor’s yeast chart in this thread, I noticed that Fermentis has a new German wheat strain, the aptly-named W-68.
A quick google turned up several online retailers in the EU and UK that carry W-68, but none in the US. I went a bit deeper and checked individual sites like MoreBeer, RiteBrew, etc., but didn’t see it listed. I emailed RiteBrew, my go-to supplier for dry yeast, and their reply was that they “don’t have any information on that strain.”
Has anyone seen W-68 for sale in the US, or does anyone have information about its availability outside of Europe? I’ve used the usual dry strains for Weizen (Munich Classic, MJ, Mauribrew, even T-58), and am eager to try this one as well.
It might only available in big commercial brewer bricks, if available at all right now in the USA, and the homebrew sized sachets will be rolled out later. Hopefully somebody will post a link with specifics under my response here.
One thing that seems really strange about W-68: “Not for refermentation (bottle or keg conditioning).” He explains that it is maltotriose positive, so if you have any maltotriose left when bottling, it could over attenuate / over carbonate. If you take this literally, you couldn’t use it if you planned to bottle condition. That doesn’t seem logical - I see no reason why maltotriose would remain after primary fermentation when using it. They probably mean you shouldn’t use it to add when bottling in case the yeast has depleted - that would make sense to me. If this becomes available, I’ll contact Fermentis about bottling to get clarification.
Shipping out tomorrow! Can’t wait to try it. I’m doing a 1bbl batch of Roggenbeir with a regular customer who is also a homebrewer in the next couple weeks. If anyone local wants a to try some let me know
Ashton Lewis (Mr. Wizard) who works for BSG made a beer with sample that Fermentis sent him and gave a positive review of the yeast. He mentioned get a significant amount of banana and clove flavors from the yeast.
I have some I’d be happy to give you. I like the yeast well enough, it has a good banana nose and some bubble gum with some clove phenols. I’m going to brew a 1 bbl of standard hefeweizen here in the next week or two as soon as a tank comes available. Still got a bit of that tartness I got from WB-06, though perhaps needs a different fermentation temp (I fermented at 64F).
That said, better hurry up on that Roggenbier – it is moving fast. Surprisingly so for an obscure beer style in Decatur, AL!
