- Why blend different pizza flours?
- Most home bakers have access to weak 00 flour (W 180–220) and Manitoba (W 350–400). By blending them in the right ratio, you can achieve any intermediate target W — for example W 280 for a 24-hour cold proof or W 320 for a 48-hour Biga dough. Blending gives flexibility without needing to buy multiple specialised flours.
- How do I calculate the W of a flour blend?
- The W of a blend is a weighted average: W_blend = (W1 × weight1 + W2 × weight2) / (weight1 + weight2). Example: 700g of W220 flour + 300g of W380 Manitoba = (220×700 + 380×300) / 1000 = (154,000 + 114,000) / 1000 = W268. This linear approximation is accurate enough for practical purposes.
- What ratio of Manitoba to 00 gives W280?
- To reach W280 blending W220 and W380 Manitoba: solve (220 × x + 380 × (1-x)) = 280 → x = (380-280)/(380-220) = 100/160 = 0.625. So 62.5% standard 00 + 37.5% Manitoba gives W280. The calculator handles this algebra automatically — just enter your flours' W values and target blend W.
- Can I blend more than two flours?
- Yes. The same weighted average formula extends to three or more flours. Many Italian professional bakeries blend three flours: a weak base (Tipo 1 or whole wheat for flavour), a medium strength 00, and Manitoba for structure. The calculator supports multiple flour inputs with arbitrary percentages that sum to 100%.
- Do I need a scale to blend flours accurately?
- Yes — a digital scale (1g resolution) is essential. Cup measurements are too imprecise for flour blending since flour density varies. For a 1000g batch, the difference between 30% and 35% Manitoba is 50g — easily measurable by scale but impossible to accurately estimate by volume.
- What about whole wheat or ancient grain flours in pizza blends?
- Whole wheat (farina integrale), semi-whole (tipo 2) and ancient grains (farro, Senatore Cappelli, Timilia) add flavour and nutrition but have unpredictable W values and absorb water differently. They also contain bran that cuts gluten strands. Keep these additions below 20% of total flour and increase overall hydration by 2–4% to compensate for the extra absorption.
