Heartland Mill

Lot Index for test data

Not all lots have data for all tests. The Hearth Bake Test is performed on UBUE, malted UBAP, High Gluten (Strong Bread Flour), Baker's Patent, and Stone Ground Whole Wheat Flour milled from hard red wheat. Our lab runs Chopin Consistograph and Alveograph tests on all our roller-milled white flours.

For lab information on Whole Wheat Flour, just match the last six numerals, which will indicate the blend from which the flour was milled, not the date of production. We mill this flour daily, and have found over the years that there is not significant performance difference within a blend.

Understanding a Heartland Mill Lot Number

For example: 02183U9A3

The first five digits of any HMI lot number are the date on which the product was produced. The above lot number belongs to a product made or packed on February (02) 18 (18), 2003 (3). The next two digits (U9) are the Product ID, in this case unbleached, unenriched all purpose flour (see ID code guide below). The final two digits identify the blend of wheats from which this flour was milled, in this case, the first (A) blend of 2003 (3). Bakers Patent and All Purpose flours (both enriched and unenriched) are made from blends identified by letter-number combinations. Our higher protein blend, used for High Gluten, Whole Wheat Flour (Strong Bread Flour), and Golden Buffalo Flour is assigned a four digit number, the last four digits of the lot number. A lot number ending in 0302 would be the 2nd high-gluten/whole-wheat blend in the 2003. 0312 would be the 12th blend of 2003.
