Fuzzel:
How'd the Nutella turn out? Sounds delish!
So do you boil the extract like you do the priming sugar? ....for fear that the extract may not be sterile right out of the package and may mess up your beer?
This is the recipe, my notes for extra chocolate and pic are at the bottom. As you can see it came out super dark, tried shining a LED flashlight through it and the light doesnt make a dent.

It turned out pretty damn good honestly, probably my favorite extract...i want to try and remake it with AG some time in the future now that i can.
The recipe called for 2 oz of Hazelnut extract and thats what i used, its not overpowering at all, but thats mostly i think because of the heavy chocolate use to level it out...i mean its 3/4ths of a cup of Baking cocoa in the boil, and then you rack on top of 8oz of Cocoa nibs for a week, not to mention all of the chocolate steeping grains...thats a lot of chocolate. And its a "Nutella Stout", you would expect a noticeable hazelnut flavor, otherwise its just a sweet chocolate stout. That said, i did order the exact same extract he linked too, mostly because i cant find anyone else selling it thats not meant for coffee...i cant speak for the potency of other extracts and how much to use or for other beer styles. All you can do is put some in your bottling bucket, rack on top of it, sample it, and go from there...if you need more you could always just rack it again to your previous bucket with more extract, or just put some in and give it a slow stir for a few seconds.
You shouldnt boil the extract, i just dipped the top of it in some starsan solution, cracked it open and dumped it into my keg then transferred the beer in. No issues, but then again even when i get lax with my sanitation sometimes, i have yet to have an infection. I mean its coming from a brewing website, if the liquid inside isnt sanitized from them i dont know who to trust...just make sure to sanitize the lid/top area where your pouring out then dump it in.
