From just a final gravity perspective, I don’t think there is any benefit in using enzymes in the mash if using gluco in the primary. However, I believe it is possible that using enzymes in the mash to break down some/most of the unfermentables before fermentation may have other effects on fermentation duration, yeast ester characteristics, hop character, and possibly other things. If I liked the style enough to brew it often, I would definitely give the mash + primary enzymes approach a chance (despite reaching FG below 1.000 with primary only in the past) to see which produced a better result.
I'll admit to primarily having, at best, only passing interest in this style. I bought a 6 pack to see what the buzz was all about and got hooked on the process more than the product. Although I truly like to drink beer, I really enjoy brewing beer. So I did my research and chased down all the fancy ingredients to brew a batch, even though I hadn't fallen in "love with first sip" with the commercial Dry PA.
With the amylase in the mash and OYL-501 Gulo yeast paired with gluco in primary, the S.G. had dropped 45 points in four days to 1.010. I transferred it under pressure to a purged keg with a speise I'd reserved under refrigeration from the original boil with a re-pitch of Gulo left over from the starter yeast. It's still krausening, and now I'm wondering if talcum powder might be wetter than my finished beer.
We'll see how this batch turns out, but what I learn from the process will hopefully carry over into improving my go-to brews.
