Currently upgrading from 19L brews to 57L brews. I have some recipes that I've done in the past that I'd like to scale up. I'm guessing I'll be tripling the grain bill accordingly but is it the same with hop additions?
No hop additions dont work when scaled up linear fashion.
Easiest way is to enter your recipe into brewing software and then change the brew length to your chosen amount....the software will work it out for you then
