It Looks Like Phlegm!!!!

[Bubblehead08]

Last night I made brew #6 which was my first AG - an Old Peculiar clone.

My chiller isn't built yet (I should have waited but I'm impatient) so I poured the boiled wort into a sanitised FV, sealed the lid on it and left it in a sink of ice water overnight. It's at the right temperature now but when I looked inside, there is a load of floating debris - now some looks like it bits of hops that must have got through the strainer but there are some floating lumps which look a bit like phlegm!!!

Is this protein, something else perfectly normal or is it something I should be worried about?

Also, I'm using a dry yeast (Mangrove Jack) which says to sprinkle directly into he wort but should I make a starter first?

That sounds like protein clumps. Because you didn't achieve the cold break this is likely what is floating around. Doesn't sound like anything to worry about. A photo would help though.

Yep you can pitch the yeast dry, or pour it into 100ml warm water around 30c to rehydrate it for 15 mins and pour it into your wort. This is called rehydration and garner you a better cell count. Not usually a need to make starters with dry yeast :thumb:

That's quite misleading...

The OP did achieve cold break, just not in the boiler and therefore cold break material flocculated in the FV instead.

The only experimental evidence I've found around cold breaking indicates that it is the minimum temperature achieved rather than the rate of temperature loss that causes flocculation of these NMPs (non microbial particles).

Sorry, I didn't explain myself properly. Thanks for the correction :thumb:

Cheers for the responses folks. Sorry, I completely forgot to take a pic but you've set my mind to rest.

I'll make sure my chiller is finished for the next brew!
