A biga is the simplest thing in the dough room: flour, water and a pinch of yeast, mixed a day ahead. Pizza Today’s dough columnist John Gutekanst gives the typical formula as 100% flour, 50 to 60% water and 0.8–1.5% fresh yeast, fermented “from 16 to even 48 hours depending upon temperature control.” That last clause is the whole decision. The flavor is real. The cost is a second clock running somewhere in your shop, at a temperature most pizzerias don’t have a shelf for.
A biga is a second dough with its own schedule
Same-day and cold-fermented doughs are one mix. A biga makes it two. King Arthur’s professional reference notes that because the biga has no salt, it “is made as a separate step in production”, mixed hours before the final dough. That is one more mixer cycle, one more tub, one more labeled time and temperature on the prep sheet, every day the pie is on the menu.
Gutekanst is candid about the trade. A straight dough, mixed in one go, “can be highly predictable, less sloppy and may fit your schedule and staff’s attentiveness.” The preferment route means “keeping a crew trained and dedicated to taking more steps to improve pizza dough.” His verdict: “It’s a tough call and it’s up to you which way to go.”
The temperature it wants is the one your kitchen doesn’t have
Here’s the part recipes skip. The American Society of Baking puts a biga at 8 to 16 hours at 59–68°F. PMQ’s report on the Italian MasterBiga app describes the traditional version as 44% hydration, matured 18 to 20 hours at 18–20°C (about 64–68°F), stretching anywhere from 14 to 40 hours as conditions change. A flour technician, a pizza maker and an engineer built an app to predict that timing from the room’s temperature.
Your walk-in runs well below that range. We’ve covered why dough boxes belong at 36–40°F for a cold ferment. Your kitchen, on a July afternoon next to a deck oven, runs well above it. Too warm, Gutekanst warns, and the biga develops “too much lactic acid activity”, the sour, slack result you can taste and feel on the bench. King Arthur lists “poor temperature control” first among the causes of an underdeveloped preferment. Pizza Today put the plain version in print: “not every pizzeria has the time or space for extended periods of fermentation.”
What the second clock pays you back
When it’s done right, the return shows up in the pie. Gutekanst credits preferments with “a stronger gluten net, moister cell structure, better taste and browning of the cornicione”, the puffy outer rim. King Arthur adds that overall production time is reduced because the final dough needs less bulk fermentation, and that the extra acidity improves keeping quality. At Anto’s in Conway, South Carolina, PMQ reports the owner uses 50% biga with 80% hydration “to create a lighter crumb” in his Roman-style dough.
One caution from the bakers: a biga adds strength, so the ASB warns against pairing it carelessly with stronger flour, “to avoid hurting extensibility”, meaning the dough’s willingness to stretch. If your skins already fight back, a biga on top of a high-protein flour can make the opening station slower, not faster.
A biga doesn’t remove the wait. It moves the wait to a smaller tub, at a temperature you now have to own.
If you already cold-ferment, the case gets thinner
Metro Pizza’s John Arena framed it for Pizza Today: “Each method is actually just a different way to manipulate time.” And: “If you have the space to do extended fermentation, direct method can yield outstanding results that are very manageable.” A shop already running a 48-hour cooler schedule is getting much of the time-built flavor a preferment offers, with one mix and one temperature.
Nor is a biga a rescue for a missed dough day. Asked by PMQ whether a preferment can speed things up, Wilhelm Rodriguez of the U.S. Pizza Team answered: “Yes, but I don’t recommend it.” A poolish or biga, he said, “could probably get you some blisters in about 24 hours if done right. But time is still the best method for fermentation, structure and flavor.”
If you do trial one, measure it the way the late Tom Lehmann taught. Answering an operator on PMQ’s Think Tank about scaling a biga, he said to set the yeast and water as a baker’s percentage (a share of flour weight) and to count the biga’s water in the dough’s total, warning that a 61% dough plus a 20% biga “might be a very high absorption dough.” His rule for a master biga: “consistency is the name of the game.”

What we couldn’t find: any published data on what a biga costs a pizzeria in labor minutes or waste, or whether customers order more of a biga pie. The temperature and time ranges above come from bread bakers and dough columnists, and they don’t agree with each other, which is exactly why the logbook matters more than the recipe. The 20% starting point is ours, picked from the low end of the ASB’s bread range; Anto’s runs 50%. Your own two weeks will tell you more than either.
