Molinos Valle del Cibao sell Princesa and Principe bread flours, both from hard red wheats. Princesa has a protein content of 12.5% and Principe has 11.7%, as per the technical data sheet. I used to use King Arthur All Purpose flour and now use Principe with no difference in the bread. The flours come in 120 lbs bags but there is a business in San Carlos who sells them from 5 lbs onward. The seller's name is Priamo, phone No.809-689-6287. He sells SAF instant yeast, also.
