I keg hopped for the first time a few weeks ago. I made the mistake of using the muslin bag instead of the women’s stockings I bought. I left the bag in too long and the beer started to taste like cotton. The last gallon of it went down the drain. Lesson learned.
That sounds like oxidation to me. I’ve keg hoped with while cones in a cotton sack before and never noticed a cotton flavor and cotton tastes similar to paper.
The fine nylon bag worked just fine by the way. Lots of hop flavor and aroma no floaties
Possibly but I don’t know how. I flush the keg with CO2 before racking. I did leave the bag in for 2-3 weeks. Definitely had cotton aftertaste so I assumed it was the bag. I will definitely use the nylons next time and take the bag out after I get the desired aroma and flavor. Keg hops absolutely impart a hop flavor.
