I bummed some DME from a bud for the last 2 starter I have done but it is time to put in a big order at NB. SO. What is the best DME for running yeast starters. I assume Pilsen as it is the lightest but that is an assumption and ya know how dnagerouse those things are!!
I use pilsen usually. I have seen recommendations for one type or another. DME is produced by mashing and boiling, then it is sprayed through a vacuum vessel to flash off almost all of the water.
The typical advice with any extract LME or DME is that DMS is all gone by the time you get it. I would guess even if it was concern, which I don’t think it is, 1/2 cup or so in a starter will have little influence in the beer especially if the starter is decanted before pitching.
