Hey, I've actually heard a bit about you from some of our club members... Good things, too.
I just read the End Game IPA post, you have some great detail there! One comment, it looks like you added your thermo-stable enzymes (SEBAmyl BAL 100/Termamyl) after the gelatinization step. I think the consensus here is that those enzymes should be in the mash from the beginning, so you get their benefit throughout all of your rests, including the high temp gelatinization.
Are those enzymes not denatured at that high temp? That 180 was my initial infusion. I did not add enzymes until the second (cold) infusion that lowered to 164f for that reason.
Thanks to your comment, I have done my own googlin' and learned that Termamyl is stable up to 194f. I will be brew a red ale this weekend and perform my normal routine *with* the Termamyl in the high temp rest and report back.
We have not been as good at that as we should. We recorded the "Fermentables" meeting and that was popular.
Gave you a shoutout on the blog piece thanking you for calling this to my attention. I will be brewing another beer tomorrow and using Termamyl at the 180f rest and documenting the effects. Thanks for letting me know about this. Is the same true of the BAL-100? I have to admit I feel like I am flying a little blind with some of the enzyme additions.
That is awesome. Do you remember who gave you your tour? We love those guys, they have been so helpful in getting the club established.
Thanks! Everything I've learned has been from this forum and glutenfreehomebrewing, so the thanks goes out to everyone.
Don’t remember his name. Thin medium height guy with a ZZ Top beard. Super nice guy and very knowledgeable about Ground Breaker brewing and about home-brewing in general.
Jesse! Fun fact: His job title is “wizard”
Excellent!
I'm curious about this too. I honestly can't remember why we landed on 170. 185 could in fact be better, considering "maximum activity" for Termamyl is around 194F. It could simply be that 15 minutes at 170 (what I've been doing) is more than enough time/temp for Termamyl to do its thing, and it's just easier to get back to 150 afterwards.
Glad you are getting some benefits from termamyl. It changed my process also. I am still considering some future improvements in the direction of a proper mash tun. My thoughts were always to implement a gravity system, mostly because I am conscious of being able to keep components clean. Pumps and transfer lines just seem like components difficult to insure remain clean. I would be interested in your setup for recirculation, false bottom etc. For my first partial mash batches, I used a cooler with a manifold. I abandoned that early on because of a few hopelessly stuck filtration experiences, usually involving significant portions of buckwheat. I went to the bag and stayed with it out of convenience. I feel like I am more experienced now and a combination of the bag and a false bottom could get me back to a better filtration setup. I am open to pumps etc. if there is experience that they can be kept clean. Anyway, I would benefit from any experience you care to share.
SEBAmyl Bal 100 is considered a medium temp enzyme, with effectiveness listed at 140-170. I think this makes it great for a single infusion, but the termamyl is much better suited for the initial high-temp rests.
