root beer foam
« on: September 12, 2012, 10:38:15 PM »
Anybody know if there's a certain ingredient used to get that long-lasting rocky, foamy head in a root beer?  I keg-carbed my 1st root beer attempt.  Wondering if bottle-conditioning it would work better (obviously in a plastic 2L)  It tasted great, but the head had no retention. 

I steeped 6 oz of rolled oats hoping to give it a thick, creamy mouthfeel and that would help the head.  Score: zero for zero.

Any thoughts?

There are additives to increase head retention and I think you can get them at homebrew shops. I was at a local brewery that makes a root beer and they had containers of 'concentrated foam' for the rootbeer. Look for 'heading agents'.

maltodextrin will add some body and head retention to your sodas.  Try using 8g or so per liter.
