Game Development: Weißbier und Käse.

Got a couple gouda recipes. Creamy Camembert aged outside or in a basement yields Generic Gouda. Two slices for 5 constitution. Pretty uninteresting, as promised.
Edit: Cellar cheddar in a cellar is also gouda.

Mothzerella outside becomes gouda, as does Camembert in the mines (I'm pretty sure, unfortunately I haven't kept good notes...)

Also, according to another source, ementaller in cellar, cave cheddar in cellar, and camembert in the cabin all degenerate into not-so-delicious gouda as well.

Here's what I've compiled so far, from the info in this thread. I'm assuming cheese aged twice in the same place automatically turns into Gouda.

Mothzerella:
Inside -
Outside - Gouda?
Cellar - Harmesan
Mine - Gouda

Camambert:
Inside - Gouda
Outside - Gouda
Cellar - Gouda
Mine - Gouda?

Cellar Cheddar:
Inside -
Outside - Brodgar Blue Cheese
Cellar - Gouda
Mine - Cave Cheddar

Ementaller:
Inside - Gouda
Outside -
Cellar - Gouda
Mine -

Cave Cheddar:
Inside -
Outside -
Cellar - Gouda
Mine -

Well, incredibly conveniently, I seem to have placed everything in the holes in the chart. I also just shoved Camembert in the mine (again?) to double-check that. I think my House cheeses should be finished tomorrow, and one of my outside cheeses. The other one's gonna take a bit longer (slightly past halfway).

[Vanigo]

A few new gouda results. Mothzarella outside is gouda, and I can confirm that camembert in the mine is gouda. Camembert doesn't age into anything interesting at all.

Edit: And cave cheddar in a mine turns into gouda.

[KoE]

The... Heck? It looks like some of the cheeses have duplicate recipes. Mothzerella in the house produces Harmesan, and Cellar Cheddar in the house produces Brodgar Blue Cheese.

[Vanigo]

Yeah, I can confirm the Harmesan indoors.
Edit: Also, emmentaler and brodgar blue both become gouda outside.

[KoE]

Emmentaller outside is gouda and cave cheddar inside is gouda. I believe that fills out Stage 2.

According to the sweet, sweet table on the wiki Emmentaler in a mine is still missing.
