brewed up a ris the other month. og was 1.084. pitched a 1L starter of WLP028. after probably 4weeks in primary at ~68 degrees fg was sitting at 1.031. expected is 1.021. I "shook" the primary to rouse the yeast and raised the temp to ~74 let it sit for another week. fg didn't drop. made another 1L starter and pitched it last week. assuming it hasn't dropped again what are my options to get the fg down further? recipe was
.5lb roasted barley
.5lb black patent
.5lb chocolate
9lb dark extract
2oz warrior for 60 min
2oz cascade for 0 min
