As a follow on to this thread I thought I'd try a batch using juice only without the expensive red grape juice concentrate.

Another twist is that I'm going to ferment the juice using the lees from the previous batch as there was no pulp and little sediment. This saves 70p of yeast :). I'm expecting this to be a lot lighter when finished than the first variant but it's £2.50 for the concentrate and therefore should be attempted.


Method

I'm fermenting this in a demijohn so won't top it up too much at first. We have the lees from the previous batch in the bottom, hopefully with lots of viable yeast.


  • Add 3 Morrisons Red Grape & Pomegranate. Total 421.2g sugar, 1212g required in 4.5L for 13.4% ethanol
  • Add 100g Tate & Lyle. Total 521.2g sugar
  • Add 1g pectolase
  • Add 2g yeast nutrient
  • Add 2g citric acid
  • Swirl until mixed

This is fermenting strongly after one day, giving it a swirl now and then.

Uh oh :(.

I can smell a hydrogen sulphide type odour in the demijohn :(.

I read that this might be due to lack of nitrogen so in went another 2g yeast nutrient.
 
Seems to be less now and it's quite a strong ferment. I might add some mulling spices to this one and put it away until Christmas just in case :). I can't really tell if there is a hydrogen sulphide smell :S.
 
After doing a little reading hydrogen sulphide might be a result of yeast cannibalism. After adding more sugar the smell disappeared.

Last of the juice went in so that should be about 1212g total sugar.

Still fermenting with a specific gravity of 0.994 at 15C. Quite a slow ferment, it might be the low temperature or perhaps the yeast was damaged from the first fermentation. topped it up to 4.5L and will let it ferment out.
