Making Herman the German starter using brown sugar

I have a recipe for Herman the German cake and starter that calls for white sugar. One of the comments said the person used brown sugar to feed Herman. It wasn't clear if she used brown sugar to create Herman. I love the flavors brown sugar gives. Can I make a starter using brown sugar? Or does it have to be white sugar to start and then I can switch to brown sugar when I feed Herman?

Here is the initial recipe and the link for the site:

• 5 oz plain flour, sifted • 8 oz castor sugar • 1 packet of active dry yeast (OP recommends using 3 tsp instead of the approx. 2 tsp in a packet) • 1 cup warm milk • 2 oz. warm water

The first link is to the starter recipe. The second link is the instructions on how to feed Herman and the standard Herman the German cake you can make with it. The third link is the recipe where she says she feed Herman with brown muscovado sugar (which Google tells me is similar to brown sugar) and wonders about starting Herman with muscovado sugar.

I'm not sure but I think brown suger can also be used to make a Herman. The Herman dough consists of Lactobacillales and yeast. Both need sugar to live. White refined sugar mostly consists of saccharose (99,96 % saccharose, 0,04 % inverted sugar syrup).¹ Brown sugar is nothing else than white sugar mixed with molasses. ² Therefore I assume that you can use brown sugar instead of white sugar. Due to the molasses in the brown sugar you might use a bit more brown sugar than the receipe says for the white sugar. Wikipedia says that "Based on total weight, regular brown sugar contains up to 10% molasses.". I think, about 10% more brown sugar and it will be fine.

¹German Wikipedia article about (the purity levels of) sugar says "Raffinade ist der kristallisierte schneeweiße Zucker mit dem höchsten Reinheitsgrad (99,96 % Saccharose, 0,04 % Invertzucker).", translated: "Refined sugar is the crystallized, snow-white sugar with the highest level of purity (99,96 % saccharose, 0,04 % inverted sugar syrup).
