No, since it is only partially covered. Read this:Could I cover my boil pot partially to prevent too much boil off, or will I run into DMS problems?
Im gonna barge in on this thread with a slightly on topic question:No, since it is only partially covered. Read this:
DMS is not a concern with extract. The initial boiling has already been done for you.Im gonna barge in on this thread with a slightly on topic question:
How does extract fit in here? does extract create DMS when heated also? I would love to do 90 minute boils, but would fear for the color of my beer if I needed to boil extract for 90 to reduce DMS further.
Im leaning towards it not being as big a DMS culprit since late additions of extract are the new favored method.
