Stella

[RichardM]

I worked for a major brewer for 25 years and am now a part owner of a craft brewery. I’m no fan of Stella but when you make it you don’t add chemicals... what ones does your friend suggest he adds?

I wonder if they treat the water with salts and other minerals. That could be what he is thinking off when he says they add chemicals.
Edit
They could also add finings
