Corn leads the mash
U.S. standards define bourbon as whisky produced from a fermented mash of not less than 51 percent corn, distilled within legal proof limits and stored in charred new oak containers.

Bourbon: The Cornfield
Before bourbon is a barrel, it is a field of grain. Federal rules require a mash of at least 51% corn, so every bottle starts with a crop that rises from seed to harvest in a single season.

The plants behind the pour
A staged climb
Corn development is tracked in vegetative stages (emergence through tasseling) and reproductive stages (silking through physiological maturity).
Source ↗Silking sets the yield
The silking stage is when pollination occurs; stress around this window has an outsized effect on the number of kernels each ear can set.
Source ↗A season in the field
General crop stages; timing varies with variety, region and management.
01
Emergence
The seedling breaks the surface and early leaves collar.
02
Vegetative growth
The plant adds leaf stages as roots expand through the soil profile.
03
Tasseling & silking
Tassels shed pollen as silks emerge—the pollination window.
04
Grain fill & maturity
Kernels fill and dry down to physiological maturity before harvest.
Ground truth before the glass
The GX-1 series angle · In grain ground, a GX-1A can record moisture, temperature and EC from planting through grain fill—especially through the pollination window—giving the grower a measured record beneath the canopy.
A root-zone record adds context beneath the crop: soil moisture, temperature and electrical conductivity at the measured location. Growers can consider that history alongside weather, field observations and their own agronomic advice.
These crop features are research context—not demonstrated crop performance, a sensor deployment prescription or a promise of beverage quality or yield.
