So HF inspired saison I've mentioned above (Omega C2C, TYB 184, Lacto brevis) that has had no off flavors to speak of as of two weeks ago after 6 months of aging and ~3 additional months bottle conditioning has now developed a relatively offputting aroma. Would lean towards butyric as it is slightly "bile-y" but not totally sure and didn't think butyric came to the party this late. Solely present in the aroma, I get none of it in the taste. Could just be something getting weird under pressure in the bottle and may need to just let it work itself out, but it's really pissing me off! Any thoughts?
