Frequently asked questions

Why does the hemisphere matter so much in a harvest calendar?

Because it flips the seasons: while Argentina harvests in its autumn (February to April), France and Spain harvest in theirs (August to October) — they never fall in the same month of the year.

Is this harvest data connected to LagarLab's simulator?

Yes. These are the same 12 real estates in the simulator's catalog, using the same soil and climate research behind the fermentation engine.

Where do the harvest festival dates come from?

From real regional sources: the governments of Mendoza and Río Negro provinces for Argentina, the interprofessional bodies of each French appellation (CIVB, BIVB, CIVP), and the Consejo Regulador of DOCa Rioja for Spain.
