First taste of my first attempt:
I put stabiliser and finings into my RGJ and strawberry kiwi today. I could see that it had already cleared a fair bit in matter of five hours so I just poured out a bit into a glass to try. First impressions were: not bad but a little harsh and acidic. I don't think I'd have been able to tolerate it in large volume.
When I made it I did end up adding about 250ml of extra juice to the recipe, because I had some left over, maybe it could have done without it.
I tried mixing a little more water into it in the glass though and also adding half a teaspoon of sugar and it tasted much better. The harshness was gone. I think on that basis that I will do that with the whole demijohn.
Final gravity was .990 - never measured the SG but think it was around 13 percent. If watering it down brings it down a bit that is fine if it makes it go down in a more refreshing way rather than harsh as it was. I can imagine that after a week or two it will improve too, would you say?
Would you agree that watering to a point of making it refreshing is the right course here or does the harshness disipate after a while without it.
