Default Dunkelweizen Off-Flavor??

I'm not real familiar with Dunkelweisens, but wanted to brew one with a little teeth, so to speak. This was a partial mash with the malts soaking at 160-150į for an hour.

The first few swigs of this dark elixer don't seem promising. Kinda metallic taste. But halfway through the glass, the malts kick in and everything's hunky-dory. At any rate, it tastes real fine to me 'cept fer the first few sips. Very malty, a tad more hop presence than German tradition. And a tad more alcohol too. This is what went into it:

BARLEY: 2 lb. Munich malt, 1 lb. Chocolate Wheat HOPS: 2 oz. Hallertau pellet

EXTRACT: 6.6 lb. MUNTONS Wheat, 1 lb. MUNTONS Amber DME

YEAST: Safbrew wb-06

Is this perhaps just the taste of this particular yeast or did I screw up somewhere?

The metallic flavor you are tasting is what people can "Extract Twang". It comes from extract in a can not the extract itself. Muntons is usually the worst. Stick with extract from this continent that is from bulk not metal cans.

3 weeks fermenting. And it's been a bit over 2 months in the bottle.

I've not had this problem with extract before, and this was bought fresh from a reputable HBS. I've been brewing with (oftentimes) Muntons for many years. You could be right, but any other possibilities?

it's probably not the extract because i made an AG batch of dunkelweis that had the same problem. almost a minerally/metallic twang and had an aftertaste that reminded me of dog crap (or what i imagine it would taste like anyway). that batch is being dumped as soon as i need the bottles. i'm leaning more toward the water as the source of the off flavor, as the the only beer i've made that didn't have at least a trace of the off flavor is a DIPA.

Maybe just a thought….Munich didn’t convert fully. It takes longer to convert Munich. Did you do an iodine test?

I didn't do an iodine test - would less than converted malt result in an off flavor?

I canít say for sure as I have always fully converted my malt but I would imagine it would leave some kind of off flavor.
