I did one the other day, used treacle and dark soft brown sugar in mine with some home malted whole oat groats, but added .5oz Fuggles for 60, .5oz Citra for 20, .5oz Tet for 15 and .5oz Galaxy for 5. Its a 3 Imperial gallon batch. Then dry hopping with .5oz Citra. Tastes good so far. Very strange taste at first, but good. Even better now with the dry hop. Get an experiment done! I love mix and match to see what goes and what doesn't.
