Adding Yeast To Secondary

[taylotim]

I am brewing a RIS and used one pack of Salfel yeast. The gravity has gone from 1.095 to 1.040 after a week - should I add another packet of yeast to the secondary??

OK here's what I think I know:

- 2 cans coopers stout
- 1kg Dark Dry Extract
- 500g Light Dry Extract
- 1 kg Corn Syrup
- 1 pack S-04
- 19 liters

Boiled all together
Colled quickly to 23 degrees
Fermented very well at about 20 degrees (in my garage)
Been going for 8 days

Appreciate any advice - I am not a great documenter....

While you probably should have added 2 packs at the beginning, I can't see why you would add it in now unless it's stuck.

When you say corn syrup are you refering to maltodextrin or dextrose? Also with those ingredients it looks to me as though your OG should have been a fair bit higher than 1095, a good 10 points higher.

Edit: adding to mantilce, I would say if it isn't moving then it prolly is stuck due to only pitching 1 pack. What alc tolerance does S-04 have? Might be pushing it a bit in that department also

I am pretty sure it is dextrose

That is a monster. I'd say it has another few points to go, 15 or so, but without putting it onto a calculator I cant say -

But it can't hurt to throw in another packet of yeast - to make sure its not stuck, and ferments right out. can it?

I have done in the past. throw it in and see how it goes mate.

I wouldn't just throw yeast in willy nilly. First wait until you know it's stuck, then try the usual unsticking methods (swirling, warming, racking etc) then make a starter with the yeast before adding it in. Just chucking dried yeast into a stalled ferment can often do nothing. If, as some people have pointed out, the yeast has exhausted its reserves then you may need to look at finishing with a yeast strain that has a higher abv tolerance.

If it is not dextrose but really maltodextrin and you used a whole kilo then I reckon you'll struggle to get much lower than 1030 and it will be a very thick brew.
