yesterday i brewed a high gravity baltic. I believe I sparged too quickly. After cooling and pitching my OG came in lower then it should have. I decided I wasn't happy with that so I Boiled 0.5 lb of DME in about 3 cups of water for 15 minutes. Cooled and added it to the wort.
I am worried that because I didn't do a full boil there may be larger amounts of Dimethyl Sulfides in that DME wort. My question is, Has anyone ever done this and what where your results? Also, Is DMS prevelent in all grain wort only, and because DME has been processed it will be absent of DMS? Its a dark beer so I am not as worried but I am curious.
