Flour + Water
Co-chef Ryan Pollnow's sister and mother both have coeliac disease.
Per-allergen evidence
Co-chef Ryan Pollnow's sister and mother both have coeliac disease. That fact drives a group-wide commitment to gluten-free. Flour + Water Pizzeria uses a dedicated gluten-free oven, a separate prep area, and Caputo gluten-free flour. The Pizza Shop and Pasta Shop locations offer dedicated ovens and pots, along with trained staff. The kitchens are shared, meaning regular flour is present. However, insider-led dedication combined with dedicated equipment makes this the strongest structural signal.
