Hi all!
I recently acquired some beer gas and a nitrogen regulator and decided to serve my Irish dry stout on nitro. I’ve pulled a few pints and the results are somewhat satisfactory, but we all know that this is not acceptable for us homebrewers
The problem is that the cascade is fairly short (less than 60 seconds) and the head forms relatively quickly. Furthermore, the bubbles are fairly large, certainly not something you would expect from a nitro stout:
Any idea where to start troubleshooting this? For what its worth, the FG of the stout is 1.016 (around 4.5% ABV).

- I’m using a 70/30 N2+CO2 blend
- My serving pressure is at 31 psi / 2.1 bar and the beer is served at around 6c / 43f (this is also the pressure I force carbed the beer to 1.2 vols with)
- I’m using a 0.5 aerator disc in the stout spout with 5 holes in it
- My beer line length is around 2 meters
- It takes around 12 seconds to pull the first part of the two-part pour (using a Guinness gravity pint)
