The process of mixing and fermenting multiple varieties of fruit is called "mixed fermentation."
"Field blend" refers to planting different grape varieties in the same vineyard and blending the grapes grown there.
Although they are all "blends," most modern blended wines are made by growing and fermenting each variety separately, and then blending the resulting wine.
In contrast, Field Blend is a method that is a revival of traditional, common methods of production.
In ancient Europe, the common wine was generally made at home using grapes grown in each household's fields. In those days, they didn't pay much attention to the variety of grapes, just harvested the grapes that were planted there, crushed them, and let them ferment naturally, which is a rather rough method of making wine by modern standards.
These old techniques were eventually refined and changed into the modern style of planting separate fields for each variety and harvesting and vinifying the grapes separately.
However, rather than using such sophisticated methods, this Field Blend is made using modern technology, but instead deliberately reviving the traditional style of mixed planting and fermentation.
The best harvest time varies depending on the grape variety, but with this field blend, even though various grape varieties are planted together in the same field, the harvest time is not changed for each variety. We look at the whole lot and harvest when we feel it is "the right time!", and then start preparing it all at once.
While incorporating traditional mixed planting and fermentation techniques, they also utilize modern cultivation and brewing techniques to effectively control the flavor.
This type of field blend can be said to be a way of making wine that expresses the vineyard itself, rather than focusing on expressing the individuality of the grape variety.
