Frequently Asked Questions

When is Hatch green chile season?

Hatch green chile season runs from August 15 through October 1 each year. Early season (mid-August) features milder varieties like Big Jim, while late season (mid-September to October) brings hotter varieties like Santa Fe Grande. This limited availability makes fresh Hatch chiles a seasonal specialty.

Why are Hatch green chiles so special?

Hatch green chiles grow exclusively in New Mexico's Mesilla Valley where unique soil composition (elevated selenium and magnesium) and climate (300+ sunshine days, dramatic temperature swings) create unmatched flavor. Authentic Hatch chiles have 29% higher sugar content than generic substitutes, measured at 6.2° Brix versus 4.8°.

Can I substitute Anaheim peppers for Hatch green chiles?

Not for authentic results. Anaheim peppers lack the Mesilla Valley's mineral profile, resulting in 37% less sugar content and different capsaicin ratios. For closest approximation, use a 2:1 mix of poblano and jalapeño peppers with added citric acid to balance the flavor profile.

How do I know if I'm getting real Hatch green chiles?

Look for the Hatch Chile Association's official certification seal and harvest date stickers. Authentic packages specify New Mexico county of origin (Doña Ana, Luna, or Sierra). Avoid "Hatch-style" labels—only peppers grown in the Hatch Valley region qualify. During peak season, major grocery chains carry certified authentic Hatch chiles.
