I believe that you will find the Medieval and Rennaisance grades of sugar
are related to the quality of processing at the location the sugar was
produced. For example, Cyprian sugar was considered superior to Barbary
Sugar. Since it was was shipped and sold in loafs, modern classifications
don't really apply.

Before 1747, all sugar was cane sugar. Andreas Sigismund Marggraf produced
beet and carrot sugar experimentally. Achard developed the commercial
process at the end of the 18th Century and the first commercial beet sugar
plant opened in 1801.

The traditional method of sugar processing was to crush the cane and extract
the cane syrup then boil it with water, lime, and albumen (from blood or
eggs) to clarify the the juice and crystalize the sucrose. This would
produce a molasses-heavy (black) sugar. The sugar is put in a conical clay
mold where gravity and moisture are used to wash the sugar crystals. The
sugar remaining in the mold is dissolved, filtered (to remove molasses
residue) and allowed to recrystalize into (more or less) refined sugar. The
process is repeated a second time with the molasses from the first boil.
Then the remaining molasses is processed a third time producing refined
sugar and blackstrap molasses.
Modern processing replaces the gravity molasses extraction with centrifugal
extraction, uses carbon particles for cleaning and decolorization, and does
not use albumen.
Brown sugar was cheaper than white sugar in medieval times because less
labor was required to produce it.
