1st all-grain - smelly pilsner

[joes99]

I attempted an all grain pilsner - Czeck yo self Pilsner. I had not read enough info about mashing and drained my cooler through a sanitized internal strainer. It was a tedious adventure but was able to keep the mash temp. It fermented for two weeks and I bottled it 3 weeks ago. I sample one at two weeks, tasted ok but smells like grass clippings cover with rotten eggs. Any idea if the odor will dissipate over time?

Recipe:
---- Danstar Nottingham Ale Yeast 2 ea
---- Weyermann Pilsner 0101470 11 lb
---- Weyermann Munich Type II 0.5 lb
---- Weyermann Cara Foam ® 1 lb
---- Saaz, Czech Pellets - Aroma/Flavor Hop 3.0% A 3 oz 1 @30,15,5 min
---- Warrior Pellets - Mainly Bittering Hop 19.7% AA .75 oz @ 60 min

Fermented at 58-60 degrees

Did you do a nice hard boil for at least 90 minutes? It sounds like you got some DMS going on there.

You used an ale yeast. It's more like a pale ale but fermented at a low temp. How was the fermentation? Did it kick off quickly?

 

[joes99]

I did a full boil.

It took a couple days to take off, I went out of town day 2,nothing happening, came home day 4 and it was going just fine

My point was that without a 90 minute boil, pilsner malt has a tendency to have DMS in the final product. DMS has a vegetal character, liked cream corn, or cooked cabbage. Pilsner malt needs an especially long hard boil to get rid of the DMS precursors.

I guess I am stuck with the odor since already bottled and carbonated.
Thanks for the info

I would worry less about the smell and more about the taste of the final product. Fermentation is a aeromatic enterprise, putting off all kinds of nasty smells.

 

[joes99]

I just finished one, kind of getting use to it, or sheer determination?

If you bottled it 3 weeks ago, let it age (lager) for a while. Most of the off odors should weaken.

Sampled another last night, 99% of odor was gone. I moved a case from my basement (68F) to the garage where it is closer to 80F, not sure if that helped but I'll take the end result. Thanks for all the input

I nioticed that too Yooper... I used pilsner in a batch of "cream of three crops"... but the smell of sweet corn (was very pronounced at first) eventually went away. OBTW? Is that you in your avatar? LOL

Sometimes cold storage (lagering) helps, but if it truly is DMS, it doesn't go away after bottling. I'm glad yours is better!

Oh, yes, that's me in the avatar. In my dreams.
