Anyone try making a yeast starter with Corn Sugar instead of DME? If so what proportions of corn sugar did you use? I am planning on brewing a high gravity stout, and don't have any DME for the starter, but do have plenty of corn sugar.

Thanks.

You need the starter medium to contain maltose and other nutrients provided by malt, or the yeast that you grow will be poorly suited and/or lose the ability to ferment the maltose in a proper wort. This is especially true when brewing a high-gravity beer.

  • This is largely important due to the nutrients in barley wort that would not be available to the yeast from simple corn sugar.

Try adding yeast nutrient if you have it.

    Yeast nutrient won't provide the maltose the yeast need.
