    Noob Questions - GF Specific

    I milled my millet and rice together at .500mm at glutarded-chris's advice for my last two batches. When I tried to mill the rice alone, I had to go to a really high gap and it didn't seem like it worked very well. But it could have just been my mill.

    Noob Questions - GF Specific

    Great to hear skleice! I too have found the chiller-heater combo to be extremely convenient. Both for chilling from 170 to 150 during the mash, and doing a hop whirlpool. I haven't had my pump get clogged. How much rice / rice hulls did you use? Yes, grain getting into the boil seems...

    Single Mash vs Step Mash

    Are you guys checking for conversion with an iodine test, or another method?

    Single Mash vs Step Mash

    Since you're using GFHB's new enzymes, I would follow their instructions because I don't think many of us around here have tried them yet (you might be the first I've seen post about using them). Personally I have been doing the 15 minute 170°F rest with Termamyl and 2 hours at 150F° with...

    Mangrove Jack M42

    I tried M44 in my last batch and it fermented very slowly, took almost 3 weeks to finish. Bottle carbonating also took long and didn't complete in some of the bottles. However, I tried it again in my current batch and it is fermenting very quickly, even with a higher starting gravity. So I think...

    Odd looking fermentation

    Looks fine. Those globules are likely due to the whirlfloc. I used it in my most recent AG brew and had very similar globules. When I don't use it, I don't see them.

    Potential "group buy" for bulk GF grains

    jguthner, are your quantities listed above still accurate? Looking to plan another batch.

    GF BIAB

    The sparge water is definitely a challenge. Even with my Grainfather I have to think about how to heat and keep that water at a certain temperature, then I have to carry and pour slowly 3-4 gallons over my mash. It's sorta the same problem you face with lifting the bag out of your mash tun, but...

    First AG batch - Grainfather - Pale Ale

    Wanted to follow up, I just bottled my second batch. It was basically the same recipe, substituting the rice malt for some light roasted millet and roasted buckwheat (since jguthner isn't selling rice malt). This time I used Termamyl, crushed my grains properly, and used enough sparge water...

    Let's talk about enzymes

    I'm glad to see their temperature recommendations. The times are a little disappointing though (2 hours for each rest recommended). I wonder why they ended up with such a long time for the high temperature rest, since most of us seem to get away with 15-30 minutes.

    Let's talk about enzymes

    I looked on the datasheet for Termamyl, it says: "The product gives optimal performance if stored at 0–10 °C/32–50 °F and used prior to the best-before date. If stored at max. 25 °C/77 °F, the product should be used within 3 months after delivery." I imagine all enzymes have a similar...

    Does anyone know if we should be storing our bottles of enzymes in the fridge?

    Potential "group buy" for bulk GF grains

    I got my grains from jguthner last week. Easy transaction!

    Let's talk about enzymes

    That's a great positive result. I actually ordered some Termamyl last night because I needed some other things from the same store. If you recall, I only used AMG-300L in my first batch, and I ended up with poor efficiency. But some of that was likely due to my poor crush size. Next batch I...

    Let's talk about enzymes

    I haven't purchased Termamyl yet, I just went with AMG-300L for my first AG batch. Last month glutenfreehomebrewing mentioned that they might be getting some new enzymes that were previously unavailable for home use, and they were conducting more enzyme tests. I think I'll wait to see how that...

    Mangrove Jack M42

    Interesting data. I've seen the Mangrove Jack's stuff all over the place recently, but I haven't had a reason to try it over US-05. If you say the flocculation is better, maybe I'll give it a try.

    First AG batch - Grainfather - Pale Ale

    I had the same worry about leaving wort in the chiller, but it's only a tiny bit. I found that you can get the bulk of it out by blowing through the tube or creating a siphon. I was mainly concerned about my temperatures, rather than the times, considering the AMG-300L instructions say 122F...

    First AG batch - Grainfather - Pale Ale

    I did use a corded drill, but I didn't know about mixing the grains together, that's a great tip. And thank you for the gap values Chris, you basically confirmed that the gap for my millet was too large and likely was the greatest contributor to my poor efficiency. rjmaillie, circulation was...
