the gunk might just be krausen that hasn't dropped, or in a bottle it might just a fine krausen ring from the secondary fermentation of bottle priming, not always bad, but best to taste it and let your taste buds be the judgepeteru wrote:Gunk on top is generally bad. Most often indicative of an infection, unless you are talking about krausen or hops floating to the top.
Gunk on top when bottled is pretty much a guarantee that the beer is off.
Speaking of brewing... Has anyone managed to do some home brewing with matrix hops? I had a taste the other day (last half-pint of a Riverside Resurrection Ale) and liked it a lot!
I think the hop you are referring to is mosaic, fantastic hop, full on passionfruit, I brewed a saison that used a fair whack of mosaic a couple of months ago, i'm down to my last few glasses and the hop character is still shining ! love it
