Wheatgrass is the young shoot of the common wheat plant, harvested at about a week to ten days old, when it looks like a miniature lawn. It became famous in the 1930s through the promoter Charles Schnabel, and later through Ann Wigmore, who built a health movement around fresh wheatgrass juice. Today the small green shots are a juice-bar fixture, and trays of wheatgrass are among the easiest things a beginner can grow indoors. The claims made for it, however, have always been grander than the evidence — the honest picture is of a pleasant, vitamin-containing green juice wrapped in a great deal of mythology.
Growing Wheatgrass at Home
You need a shallow tray with drainage, an inch or two of potting soil or a growing mat, and hard red winter wheat berries, sold cheaply as wheatgrass seed. Soak the seed in water for eight to twelve hours, drain, and let it sprout for a day or so until tiny root tails appear. Spread the seed thickly and evenly over the moist soil — the grains should nearly cover the surface in a single layer — then cover the tray with another tray or a damp cloth for two to three days, misting daily, to encourage rooting. Once the shoots reach an inch or two, uncover the tray and move it into bright indirect light. Water lightly to keep the medium moist but never soggy. The grass is ready at six to eight inches tall, typically day seven to ten. Mold, the main enemy, is discouraged by good air circulation, not overwatering, and washing the seed before soaking. Cut the grass with scissors just above the seed line; it will regrow weakly for a small second cut, but most growers compost the mat and start over — wheatgrass grows so fast that a weekly tray costs pennies.
Juicing and Using It
Grass blades are fibrous and humans cannot digest them whole, so wheatgrass is juiced. A slow, masticating juicer (or a hand-cranked grass juicer) extracts far more juice than a centrifugal model, which mostly shreds and spins the blades dry-ish. The standard serving is one to two ounces, intensely green, sweet at first with a strong grassy finish. Many people mix it with apple, pineapple, lemon, or ginger. Juice is best drunk immediately, as it oxidizes and its flavor deteriorates quickly; freezing in ice cube trays is the common workaround. Dried wheatgrass powders and tablets are also sold — convenient, and gentler in flavor, though dried products differ from fresh juice in composition.
Nutrition: Claims Versus Facts
Wheatgrass juice does contain real nutrients: vitamin A, vitamin C, vitamin E, vitamin K, several B vitamins, iron, calcium, magnesium, amino acids, and chlorophyll, which makes up much of its dry weight and accounts for its color. Two famous claims do not survive scrutiny. Wheatgrass is often said to be extraordinarily concentrated — “one ounce equals several pounds of vegetables” is a marketing line rather than a measured fact; its nutrient levels are broadly comparable to those of other green vegetables, ounce for ounce. And while “detox” language surrounds it, the human body detoxifies itself through the liver and kidneys; no juice performs that job for it. Small studies have explored wheatgrass in specific medical contexts with preliminary and mixed results, but there is no solid evidence that it treats or prevents disease in healthy people. Enjoy it as what it is: a fresh, green, vitamin-containing drink.
Wheatgrass can cause nausea in some people, especially on an empty stomach or in larger servings, so start with a small amount. People with wheat or grass allergies or sensitivities should be cautious — the grass is cut before gluten-bearing grain forms, but seed residue and individual sensitivity vary.
