I generally like the location based aging mechanic though I think cheese goes a bit overboard in it's complex usage of the mechanic. Any game mechanic can be abused but in principle this is a good one, it's rather original, is simple to use, it has a localizing effect on industry, it takes weight off ingredients and it makes for a more holistic process then a kind of Alchemy. I really like the idea of multiple products being created from the same source materials.
Also with respect to wine, I think most of the difference in wine comes from particular grape varieties interacting with climate, while that would be interesting to model I don't think the terrain/climate model is really sophisticated enough for that yet. Also I've never heard of fermenting temperature being a significant factor but I could be wrong. The main distinction in wine is if its white or red so making that split first would be most appropriate. Simplest way I can see is having a wine press produce 'white grape juice' from grapes, if the white grape juice is fermented it makes white wine. But if the white grape juice is left in the wine press for say ~5 minutes it becomes 'red grape juice' which becomes red wine.
