AHOY! Definitely yeastbergs. I have witnessed them many times.

Explosive fermentations are a great show, don't mean much as far as great beer.

I HAD EXACTLY THE SAME THIS WEEK !!!!
I just posted on the all grain thread and decided i should move it here !!

(not trying to hijack but we have the same problem ! )

This is my original post :

-----------------------------------------
Two weeks ago I brewed this :

Murphy's Irish Stout

Yield: 5 Gallons OG: 1.040-1.043 FG: 1.008-1.010 ABV 4.2%
SRM 81

AG

5.75 lb British 2 row
1/2 lb chocolate malt
7 oz Roasted Barley
4 oz British Crystal 55 L

Mash for 90 minutes at 150 f (2.5-3 gallons at 162 strike temp)

1 oz target (boil 60 minutes)
1/4 oz E. Kent (Flavor, 15 minutes)...don't forget Irish Moss here

yeast: Wyeast 1084 Irish Ale or 1098 British Ale ***Substituted Safale 04***

--------------------------

I wanted to wash the yeast, and when I racked to secondary after 9-10 days, the trub looked like nothing I've seen before (4th batch) it looked almost like broccoli !! The trub I've seen in the past after racking was like an opaque yellowish honey/taffy on the bottom of the ale pail, but not so this time.. i washed it anyway according to the yeast washing sticky, and the jars of washed yeast looked like his did after 1 year. (looks like sweet tea with a thin layer of whitish powder on the bottom)

I bottled it yesterday and there were still some little brownish/greenish floaties on the top, that I thought were hops, but after squeezing them in my fingers, appear to be parts of the broccoli trub !! It should also be mentioned that the beer was delicious! it was supposed to be a murphy's clone and it tasted great, even to my brewing friend with much more experience...

so does anyone have any advice ? ever seen the mysterious "broccoli trub" before ?? am I going to die when I drink this delicious brew ? are the jars of washed yeast worthless ?

Thanks so much !
Joey

- I'd still be sitting in my shed drinking beer instead of brewing it, without you guys ! -

So I bottled it, and tried to keep the "yeastbergs" out of the bottles, it was in the primary for 2 weeks and the secondary for one week.. holding the bottles up to the light,i could still see a few of the yeasties in the bottle.. i cracked one open and sure enough, 20-30 yeast spots floating around the bottom.

Is this stuff OK to drink, will they settle or break up .. are they alright to drink ?
