1. The AVPN International Regulations

The Associazione Verace Pizza Napoletana (AVPN), founded in 1984 in Naples, protects the heritage of true Neapolitan pizza. Under EU Traditional Speciality Guaranteed (TSG) law:

• Four Ingredients Only: Wheat flour (Tipo 00 or Tipo 0), natural drinking water, sea salt, and yeast. Absolutely no olive oil, fat, sugar, or dough conditioners are permitted.
• Baking: Baked strictly on the refractory stone floor of a wood-fired or gas oven at $430^circ ext{C}$ to $485^circ ext{C}$ ($800^circ ext{F}$ to $900^circ ext{F}$) for exactly $60 ext{ to } 90 ext{ seconds}$.

2. Micro-Dosing Yeast & Temperature Dynamics

The secret to the ethereal, cloud-like, highly digestible cornicione (crust) of Neapolitan pizza is micro-dosing yeast. While ordinary American bread recipes use $1%$ to $2%$ yeast, traditional Neapolitan pizzaioli use as little as $0.05%$ fresh yeast ($0.5 ext{g}$ per kilogram of flour!).

Yeast metabolism doubles approximately every $10^circ ext{C}$ ($Q_{10} approx 2$). At warm room temperatures ($26^circ ext{C} / 79^circ ext{F}$), yeast must be reduced by nearly $40%$ compared to a cool $20^circ ext{C}$ ($68^circ ext{F}$) kitchen to prevent the dough from over-proofing and collapsing into an unmanageable puddle.

3. Cold Fermentation (CT) vs Ambient Room Temp (RT)

While classical Neapolitan pizzaioli ferment exclusively at ambient room temperature for $12 ext{ to } 24 ext{ hours}$, modern artisans employ cold fermentation (CT) at $4^circ ext{C}$ ($39^circ ext{F}$) for $24 ext{ to } 72 ext{ hours}$. In the refrigerator, yeast metabolism slows to near-dormancy while bacterial enzymatic proteolysis continues, breaking starch into sweet maltose and proteins into savory amino acids (glutamates), yielding unmatched leopard-spotting and complex artisan flavor.
