Fermenter crafting recipe

[Brennon]

How do you make a fermenter? It's not showing up for me in the hammer or workbench lists, wondering if I'm missing any materials

[Monokuma]

I forgot what material I had picked up to unlock it, but you'll at least get it by the end of the Black Forest if you're gathering the ores and chopping the new trees.

i think it was bronze

[Brennon]

I already got core wood, bronze and bronze nails but I see nothing

[Monokuma]

Maybe try fine wood from the birch trees?
