Hey guys,
I was looking for a little advice on this one - I put this together on Thursday night hobo style (doing it as an exercise in cheap homebrew for some university students who have 0 budget):
3.5l Asda SP apple juice
1l Cherry Vimto (boiled for 15m)
190g Sugar (boiled for 10m)
25 Raisins (instead of yeast nutrients - seems to work in hobo mead recipes)
Young's yeast (unmarked but from Bitter starter kit)
I've got it all in a 5l water bottle with a pin pricked balloon on the top and there's a veritable storm of small bubbles rising to the surface.
Anyway - I took a OG reading of 1.066 on Thursday night. On Friday though after bubbling for about 18 hours the gravity reading had gone UP to 1.075. It's quite possible I took the reading wrong (or the acid made the raisins release all their sugar, although that should only have added ~11g of sugar).
Last night around midnight it was at 1.050 - and just taken it now (~12 hours later) at 1.035! We've tasted it to now and there's an awful lot of sweetness left, I'd guess around 6% alcohol but very little vimto flavour.
Now ideally I want to take it to a halloween party on Friday (as Satan Juice) - and could do with getting it carbonated with more vimto in it.
So I'm thinking I can't stop the fermentation or I won't be able to to force a small secondary fermentation in it to fizz it up. Also to get more Vimto flavour into it I need to get rid of more of it's current sugar or it will be way too sweet.
Would I be right in thinking I just need to let it run it's course (the speed it's going it should be done by Tuesday morning) then bottle it adding 40ml of Vimto to each 2l Pepsi Max bottle, leave it in the warm for 2 more days then fridge it (hopefully Thursday morning with an aim to clear it as much as possible by Friday night - not to fussed on clarity, it looks evil atm). I know it will be pretty dry if I let it run it's course but Vimto does contain Sucralose and Acesulfame K which should help - another option would be to use No Added Sugar Vimto for sweetness and more flavour - and either normal sugar, or "half spoon" for fizz.
I got the 40ml figure for the Vimto as the bottle says made up 1 part Vimto to 4 parts water 100ml contains 4.7g so 40ml should contain just under 10g of sugar per 2l bottle.
Does this all sound right? - I'm totally new to homebrew and really looking at beer (which is going well) but did this as a laugh for a mates son.
Oh final question - should I leave a 500ml headroom in each bottle just in case?
