Wyeast is not GF but if you use Wyeast liquid then mathematically your glutem ppm would be around 2 which falls below European standards. I want to try Wyeast but if I get sick after drinking I dont want to dump the whole batch... might be worth a try in a smaller batch.

Thanks BBBF- where do you get that? My homebrew store only sells White Labs...

Just added some DAP and it started to bubble more only seconds after I put the lid back on!

So how much DAP/gal for beer then? I know they say if you are all grain you don't need it but what is the target range? Yeast says 1/8t per 2L starter but that's also using DME.

dont worry about it, throw it in at the end of the boil, use about 1 tsp (no more), and you will have a nice strong fermentation. this stuff helps take out the metalic taste in the sorghum malt, i think the sorghum stresses the yeast and thats why you get off metalic-flavors. But thats only my opinion.

1tsp for a 5 gallon batch?

Hi Everyone,
I need some expert advice on DAP here! I've been brewing for a few years and usually get it reasonably ok. This time I'm very worried though: I usually keg, but decided to bottle half of my current 10 gal batch (irish red ale with oats). I boiled 4oz of priming sugar and distributed it evenly across 9 sanitized 2L growlers. Then, being the genius that I am, I decided to add a small bit more to increase carbonation. SO, I picked up the bag and poured a little (maybe one tsp) directly into each 2 Litre growler. After racking and sealing the bottles, I realized that the second bag I used was not priming sugar at all...
It was actually DAP (Di Ammonium Phospate), which is a nitrogen aid with a recommended use of 1/2 to 3/4 grams per gallon. So, I have used at least 10 times too much.

My question is: do I have to throw out the batch?
(I am aware of the pressure issues and am conditioning in a vented cooler box.)

Any info is appreciated!

It might have a metallic/salty taste to it. Let them carbonate, taste and find out. Even if there is an off flavor, I would set them aside and taste them over time. Maybe it'll improve.

I was one of first to start using DAP, that was a few years ago. Ive used it on probably 30-40 batches, heres my take:
1) I use it sparingly, maybe a level tsp at most, or even 1/2 of that.
2) Its like fertilizer, it doesn't matter when you add it, really its just a nutrient.
3) If you add too much it will taste and smell slightly sulphury at first, even that will go away (most all of the time) with a little time.
The stuff is great, if you use sorghum as a base and proper brewing techniques fermentation temp etc you will get a nice tasting beer. Its gonna be dry as its the nature of sorghum, but there are other ways to get around that too.
