Cider stopped fermenting at 1.020
 
Hi all,

I've done a few batches with a few different kinds of beer before, so I thought it was time to give cider a go. I used a black rock cider kit with 1kg sugar, can't really go wrong, right?

Well, the airlock stopped bubbling after day three. On day 4 I took a hydrometer reading, got 1.020 and it was still very sweet (tasted just like apple juice with a slight hint of alcohol). On day 8 another reading, same story - 1.020, sweet tasting.

So any ideas? Temperature started at about 26C and has been running around a constant 24 from then (that's 79F and 75F to old people ;) Would it be worth mixing it a little in case the yeast is 'trapped'? Or adding new yeast in case the old stuff has somehow died?

Thanks in advance.

What kind of yeast did you use?

I used 40702 cider yeast.

Guess I'll need someone else to pipe in on this. So what was your recipe exactly 5 gallons? I'm guessing that's about 4 cups of sugar? What was your hydrometer reading when you started?

I personally have only used Wine Yeast with Cider, I haven't used Cider Yeast. The 2 gallon batch I made with wine yeast got it down to 1.000.

The initial gravity was 1.056, but I'm not sure how accurate that was. It was 1kg of sugar, so yeah, about 4 cups, made to 23 litres (5 gallons).

It's still exactly the same. As far as I know, the only options I can try are adding more yeast, or mixing it up.

You may want to go ahead, and let it go a few more days, if it's STILL at 1.020, then you could try adding more.
