Crazy low FG....?

[einnebcj]

Into the second week of fermenting the coopers clone on the recipe database. 18l stovetop BIAB. brew day went off well and starting gravity was bang on the money. Took a sample tonight and dipped the hydrometer in - 1.004! Recipe sees FG at 1.012. Big difference! The sample was heavily sedimented - dead yeast and probably got a little more trub in the fermenter than ideal. Could this impact the reading?

Thoughts?

Cheers

I've wondered about trub altering gravity readings in the past. I did a few tests swirling large amounts into some samples and found no significant change in gravity readings.
My money would be on mash temps. What was your mash schedule?

 

[Fat Bastard]

I find the gravity climbs on the refractometer a little as the trub drops out, but maybe only by .002-.003.

Lots of other factors to consider, mash schedule yeast health etc. Have you done this brew before?

Did you use a refractometer or hydrometer for that reading?

dipped the hydrometer in

Coopers yeast is a beast.

db calculator has never been accurate.

Being stove top BIAB - grain put in at 70c and mashed for 90 minutes - approx 13l of water. After 90 temp was 61 with a reading of 1.030 - adjusted to 1.044@20c

You've probably spent a significant amount of time in Beta town, producing a highly fermentable wort, combined with the Coopers yeast has got you down under where you want.

Kegs or bottles?

Maybe you could steep and boil a little spec malt and add? Considering this myself on a CPA kit Brew I have in atm that I feel lacks a bitof body (go figure)

 

[einnebcj]

In bottles......can you expand the spec malt solution....uncharted end waters for me......

 

[einnebcj]

So...should I just continue and bulk prime in a few days or......other thoughts? What will be the result....just a high alcohol content or will taste....head retention...other been affected?

I did the same recipe clone with recultered yeast from a dozen stubbies in a double batch.
biab no chill in the fermenter @1038 done @1002 .

what did it taste like?

what did it taste like?

if your talking to me
well it tastes bloody good i'm drinking as I type

 

[einnebcj]

Well that's reassuring Gabba.....thanks. Never had one drop down so low! It's as low as the cider I've got sitting next to it at the moment!
