Haha, I do that sorta thing all the time and I teach maths to children, I'm a liability in that department! Thanks Matt mate

Nice one thanks oldbloke

any chance you can explain the calculation mate?

I have 4.5 litres of finished WOW at 12.7% ABV however it finished at 990 and is over dry so I'm planning on back sweetening with 150mls of grape juice just to take the edge off. Is there a calculation I can carry out to work out what the new ABV will be?

I have my wow fully fermented out, and have let it sit for just over a week. It's begging to clear, the top half of the DJ is pretty translucent, how do I know that the yeasties have cleaned up all the nasties they left behind whilst fermenting and when to rack it?

I'd read that 9% is absolute minimum. Its of no interest to me, 11% at least or I'm not bothered :)

Nice one. I suppose mastering the hydrometer and sugar quantities needed ( prefer 11 -12% - weak enough to attempt drinking a second bottle ;) ) is a good excuse to acquire more DJs and get more brews on the go. Happy days

I shall measure the capacity of my dj when it's empty, then use the 20g per litre = 1% rule I think oldbloke told me last time I was asking for help. Appreciate it thanks mate! Chippy you're a legends Well you both are, cheers fellas! Spot on

Nice one oldbloke chippy says 1100g for 14% Who to trust?!?! Hahaha :thumb:

Cheers chippy mate I shall allow it to finish then let it down with a little water and grape juice to sweeten and hope it takes the % down a little. How much sugar would you suggest for 12%? I trust your advice more than the chart I used which must be wrong

Yeah mate, standard gallon dj. So the 1.068 looks right? So there's a flaw with the chart I used? The measure was spot on, digital scales that set themselves at zero when you turn em on with the bowl on top.

Reading was 1.068, I was expecting 1.090 or close

There was 228g of sugar in the juices so I used this chart http://www.brsquared.org/wine/CalcInfo/HydSugAl.htm to calculate I needed to add 860g of sugar. I did add boiling water to it and heated it on the stove. Is the boiling water an issue? DJ was filled to just below the shoulder

Made it into a syrup buddy as I thought the reading would be off with sugar poured straight in, could that have affected it? I had considered if I had stirred it enough though I really made the effort to and gave it a good shake

Hi folks, total beginner so be patient :) Was having a bash at a straight up wurzel following the recipe, calculated the sugar I would need (was aiming for 12%), weighed it out, added everything to the DJ,mixed well and took a hydrometer reading however it was telling me there was a lot less...

Hi mate Chances are you're misreading your hydrometer, have a good look at the scale and you'll likely realise your readings are 1.082 and 1.092. From one newb to another haha! Made a similar mistake myself when I started. I feel less like the new boy now :D

Will the wow method work with just grape juice?

Thanks for very useful replies! Most helpful! If 1100g sugar will result in 13% abv is there a formula I can use to tailor the sugar to 11 or 12% abv?

They do state approx ABV but I'd like to be able to check progress, specially whilst the temperature is fluctuating a bit in winter. I'm more interested in calculation for the supermarket juice wines

Any chance you can explain the calculation buddy? I know I'm a pest, I could just use all the help I can get thanks!
