What A2/A2 milk is
A2/A2 milk comes from cows that produce only the A2 variant of beta-casein, not the A1 variant. The two variants differ by a single amino acid; A2 is the older, ancestral form found in heritage breeds (Jersey, Guernsey, Brown Swiss, Devon, Normande). Most modern Holsteins produce a mix of A1 and A2 because the A1 mutation spread through industrial dairy genetics over the 20th century.
A2/A2 raw milk combines the genetic profile of pre-industrial dairy with the unprocessed format of pre-industrial dairy. For many people who cannot tolerate "regular milk," A2/A2 raw milk is digestible without symptoms.

The Manhattan A2/A2 route
- Cows are milked at a small A2/A2-tested herd at a licensed New York dairy.
- The milk is bottled the same morning in half-gallon glass.
- The Saturday route runs the cooler from the farm to Manhattan.
- Cooler on your stoop Saturday afternoon.
Why A2/A2 raw milk specifically
- Digestibility. The A1 protein produces BCM-7 (beta-casomorphin-7) during digestion, which is implicated in some "milk intolerance" symptoms. A2/A2 milk does not.
- Intact lactase. Raw milk preserves the native lactase enzyme; pasteurization destroys it. Many people who are lactose-intolerant on store milk drink raw milk daily without symptoms.
- Pasture-fed nutrient profile. Grass-fed, on rotational pasture, the milk is dramatically denser in vitamin K2, omega-3s, conjugated linoleic acid (CLA), and butyrate than confined-feeding industrial milk.
- Heritage breed cream. Jersey and Guernsey cream is famously rich; the cream layer in a half-gallon glass is generous and recognizable.
Is A2 milk available at Whole Foods or grocery stores in NYC?
Some commercial A2-branded milks (a2 Milk Company) are available pasteurized and ultra-pasteurized at Whole Foods and select grocery stores. They are A2/A2 by genetics but pasteurized and homogenized; the heat-sensitive enzymes and the cream layer are gone. Raw A2/A2 milk is not sold in NYC retail; it is delivered farm-direct from licensed dairies.
