Then you can do what I described for the 50a breaker and 6awg wire in the last post.

Also, note that with the 50a GFCI spa panel you will need to design your control panel to live within 50a. You could go with a 60a GFCI spa panel if you needed the extra 10a of headroom.

Maltose, you have a 60a main breaker, and a 50a GFCI spa panel. What do you want your brewery panel to support (element size, how many at once, PIDs, pumps, etc.)?

Yeah I've basically got all the parts for a 30A panel so I'd like to feed it with only 30

Let's say I keep the 50A coming in....where would I be running my wire after it comes into the panel at 50A? I'd probably hard wire 6/3 with ground into the panel that would go into a first circuit breaker.

Thanks for everyone's help so far.

I did something similar (ish) - 50a (6ga) from panel to spa panel to control panel. 6ga hits contactor, goes from there to 4 distribution blocks (Hot A, Hot B, Neutral, and Ground). 10ga from the Hot A / B a very short distance to 2 internally mounted DIN 25a breakers and 1 15a breaker. From those, appropriately sized wire to individual components. You could do the same and survive, or put a 30a breaker in the Spa Panel like jeffmeh shows in the link above.

That certainly works. I would expect the 30a breaker with all 10awg would be less expensive than the two 25a breakers with 6awg, particularly if there is a long run.

Agreed. I did mine because I want to run both elements at the same time so I needed the full 50a capacity. If OP only wants 30a, there's no reason to run 6ga. The easiest (cheapest?) thing to do would be to replace the 60a panel in the main breaker, run 10ga to the spa panel and then to the control panel. Even in a relatively short run it'll probably pay for the cost of the 30a breaker in savings on wire, not to mention the smaller size is way easier to work with!
