Free-run wine is wine from juice that freely flowed from the grapes / must before it was pressed. With white wine, this occurs in the press (but before pressing). The grapes split open under the weight of the bunches on top and release a part of their juice. With red wine, the free-run wine (or ‘vin de goutte’ in French) is the wine that flows from the tank after fermentation, but also before pressing. The wine that is produced after pressing is called ‘press wine’ and is often perceived as qualitatively less because extra acids and especially tannins are released during pressing.
