So I don't understand this and have never used these products .... teach me.

I like Scotch & dry ginger as a long drink. Let's say I dilute it 1:4 with my mixer, so that's reducing it to only 8% abv in my glass.

According to their website, 8kg of sugar in water to 25 litres with Alcotec 48 yeast will produce 25 litres @ 20% abv in 5 days. Now that's 320g sugar in the litre which will give OG 1.115 so I fail to see how 20% is achievable unless it ferments down to 0.968 - is that possible? I've never had a dry wine ferment below 0.988 - what's the theoretical gravity of 20% alcohol in water? Am I missing something glaringly obvious here, do I somehow lose 4 litres over the process?

This product then needs charcoal treatment. Thinking aloud, could you run it through a Brita filter?

Supposing I end up (after clearing and racking) with 22 litres at 20%. 8kg of sugar will cost me £6.40, the yeast's around £3, say a quid for finings and £2.50 for a filter cartridge, that works out at 60p a litre.

Balliihoo's flavouring essences are for 75cl of 40% spirit but I will only be diluting my ‘whisky’ flavoured drink 1:2 to get the same 8% abv in the glass so I assume I use one bottle of essence to flavour 1.5 litres of drink?

Bottom line: It's going to cost me around £2.80 for 1.5 litres of 20% ‘whisky’ flavoured drink when the cheapest supermarket own brand blended Scotch now seems to be around £11, so that might be worth a try, but would this actually taste anything like a cheap blended Scotch even when drowned with dry ginger? Who has made these brews? Has anyone made them more than once?

Is this not over ambitious expectations written by the companies copy writers :whistle: :whistle:
 
SG H2O = 1.000
SG C2H6O = 0.789

4 * 1.000 + 0.789 = 4.789

4.789 / 5 = 0.958

Seems legit...
 
My little calculator estimates 8kg of sugar in a 25L batch to get down to around 0.985, which is around 18%.

That's with Youngs Super Wine yeast though, as I don't know how aggressive Alcotec is.

I've tried fermenting sugar water with wine yeasts, it doesn't work.

It doesn't seem to matter how much nutrient you throw in, they still turn around and tell you to get stuffed.

Ahh, strange that. The calculation is just based on the attenuation though, I'm guessing that the Alcotec stuff will have a higher attenuation?

I definitely think between 18 and 20% is very possible regardless :)
 
yeah definately doable, i do a v nice alcholic sodawater for mixing with the sodastream concentrates using tromozymol and champagne yeast- i think this yeast is best cos of its v low flavour profile- if anything is kinda peachy- and rapid flocculation but ive only gone up to 8%- which is probably the way to go- as get lovley natural carbonation and no nasty e numbers
ie making a 8% ginger beer then adding scotch extract to the glass- job done :)

Don't know if the carbon in one of these would produce the desired effect, but if you try it then I think you'd want the wine to be very clear first, otherwise I think the filter will clog up really quickly.
 
In my experience it'll probably go to about 18% before the yeast waves the white flag, I think the 20% is "under lab conditions"

The charcoal was certainly neccesary for the one I made, it was cloudier than a summer's day in Bolton. To speed the process I placed my DJ in a cold water bath and it dropped bright in 3 days.

Most filters recommend use with clear water only, so it'd have to be pre-filtered or cleared before running it through the Brita.

Whilst the Brita does have a charcoal bed to remove taint it is there to remove the taint of chlorine from the water. I'm not sure how it would cope with 4lts of alco-wash. :wha:

YMMV
