Not good news
I used to like smoked meat from a WSM , UDS or kamodo as much or more than an offset, I actually liked a little charred fat taste!
Well for the last year the smoked meat from a vertical smoker where the fat dripping vaporize has begun to taste BAD!
Not cooking differently just don't like the taste anymore.
It's a bummer, my offset is great in warm dry weather but my kamodo will cook in cold weather in a rainstorm & just chug along.
Gotton so bad I'm thinking of getting a cheap pellet grill & a good welding blanket
