Final SG Of Finished Fermentation

Afternoon all

I think my wash has now finished fermenting. No more bubbles rising and an SG of 1010. Do you think its ready for the next stage.

Cheers

What's in it? 1.010 does seem a little high unless it's All Grain and even then....

I thought it was a little high tbh. Its made with 6kg of sugar and the last of my Still Spirits turbo yeast and carbon pack.

There's still quite a bit if sugar left in that, I expect my sugar washes to finish below 0.990

Are you using any form of temperature control? I use a thermostatic aquarium heater to keep vodka star at 26C and lentil washes at 28-30C.

Yup that's a bit high .. is it bubbling through the airlock?

If it's in a bucket then airlocks are rarely a good indicator. I have only ever had one which sealed properly, if there's any pressure leak around the lid then bubblers won't bubble,

@Stillbrewing: It may indeed be still brewing. 1.010 would indicate there is still sugar remaining. The question is whether or not the wash has become stuck or not. If it has, run it and take the small loss. Next time will probably be better.

As you are stating "no more bubbles rising",my own indicator,(assuming no attempt at an airlock)I would declare this one ready to rack and run.
As others have stated,it is still high in sugar,for some reason.
Something to ponder upon.
But personally,I would run it.
The yeasties could have done better for you.
Ask them,and yourself why they didn't.

Hold off on the Doomsday solution a while ;D

The worthwhile principle of 'Exhaustion of Remedies' suggests you a should give it a mighty stir, re-seal the lid and airlock and leave it a couple of days to see if the gravity reading improves.

Often, little is learned by throwing in the towel too easily.

Agree with what the others have said.

I used to panic when the airlock stopped bubbling. What's gone wrong ? Is it stalled? How do you make a nutrient bomb? I have much more relaxed attitude now. If you used a decent amount of yeast to kick it off then it's likely just slowly chomping its way through the wash. Stick your head in the bucket and have a sniff. If it feels like someone's just jabbed a pencil up each nostril it's still fermenting.

Fruit ferments sitting in a bowl on the sideboard. No airlock. No Ph strips or dap. Yeast will triumph over us all in the end . O0

Cheers for all the help and info gents.

I gave it a right good stir and left it a few more days. The temperature was fine and it finally dropped a little more down to 1004, but no more.

I've now gone ahead and racked it off and started the clearing process as its been brewing for over two weeks now and I want to avoid any sort of infection. TBH, I have never managed to get the FG much below 1000 before. Don't know why, I have always kept the temperature right and have even used a stick thermostat when its been cold.

From now on I'm going to try the Vodka Star yeast like you guys do as I have been using Still Spirits packs from day one. Maybe that might make a difference.

Have you checked the pH? It can really dive on a sugar wash and that will stall the yeast.

Hi Chill

No, I didn't check the water PH, its something I never thought about. On this occasion its too late because I have already cleared it ready to go into the still but will grab a testing kit to add to my armoury.

When it comes to making spirits I'm a complete novice and have always made it the same way as shown in the vids by a UK supplier of Smart Stills. Now that I know a finer spirit can be made at home using this basic still I'm very eager to learn.

I don't think I will ever be able to upgrade from the Smart Still so I hope I will get the best from it.
