why "¼ of the harvest is made into wine" was not considered?

Hi Yushan,

I think this is an interesting question that may be relevant for many people. I would be happy to share my thoughts on it:

• Your observation is likely correct, as reselling the grapes would likely result in a lower price compared to wine production.
• Therefore, the calculation should have been divided into two parts, with 2.75 ha (i.e., ¼) allocated for wine production and 8.25 ha (i.e., ¾) allocated for reselling the grapes.

If you would like a more detailed discussion on how to address your specific situation, please don't hesitate to contact me directly.

Best,

Hagen

The yield does not depend on how you allocate production. I.e., the yield of the field is exactly the same regardless of allocating 0%, 25% or 100% to wine.
