Wheat

Triticum aestivum

Wheat is the grain most closely associated with flour and bread. Its gluten-forming proteins are what give wheat dough its characteristic stretch and structure, but wheat is also a set of grain classes with meaningfully different behavior in the kitchen.¹

In New England, wheat is no longer just a historic staple remembered through old gristmills. University of Maine variety trials are explicitly aimed at identifying spring and winter wheats adapted to organic production in the region, which is one reason local grain projects now talk about wheat alongside rye, oats, and barley as a realistic food crop rather than a novelty.²

Hard and soft wheats behave differently before any baker touches them. McGee notes that hard wheats have stronger protein matrices and are preferred for bread, while soft wheats mill into finer particles and make weaker gluten better suited to cakes and pastries.¹ The familiar winter-versus-spring distinction matters too: it is partly agronomic, but it also shapes which wheats fit a Northeast season and which end up in local trials.²

Gluten is chiefly a mixture of gliadins and glutenins. Gliadins contribute extensibility and flow, while cross-linked glutenins contribute elasticity and strength; their balance helps explain why two wheat cultivars with similar protein percentages can still behave differently in dough.³ That distinction helps make sense of why a local wheat can be excellent for one use and frustrating for another even before freshness, extraction rate, or fermentation enter the picture.

Whole wheat is also structurally more than flour plus bran. Milling decisions determine how much of the bran and germ stay in the flour, and white wheats are often preferred for whole-grain flour because their lighter bran tastes less astringent than red wheats.¹ In a regional grain notebook, wheat is therefore less a single ingredient than a family of milling and baking possibilities tied directly to cultivar and place.
