Hi all,

Wasn't sure where to post this, so I'm trying here...

I made a sugar wash that started at 1.060 and finished apparently at 0.860. Now I couldn't believe what the online calculators said, but then when I worked it out ((1060 - 860) / 7.4)= 27.02% ABV.

That can't be right, can it? I used EC-1118 and I didn't think it could tolerate anything more than 18% ABV?

Have I got my calculations wrong or have I made something absolutely mental?

Recipe was tap water, campden treated, 4kg white sugar, Omega Propper Seltzer nutrient, EC-1118 yeast.

Forum calc gives 26.25%.
What will you do with it?

Split it over two kegs, flavour one with lemon and lime juice and one with strawberry Lowics syrup, gas it up and have 60 pints of hard seltzer for about £15, which would have bought maybe 8 x 250ml tins in the supermarket.

Also, I'm going to learn not to randomly fire 4kg sugar into a fermenter because I thought I was doing a wine kit without checking anything else.

Hi Harry. I think your FG must be wrong- that's a drop of 200!!!

I know, that's why I asked the question. I've checked a couple of times with a hydrometer, and while I expected it to ferment dry, I didn't think it'd be .86 - I'll just assume that's wrong and go with it fermenting to 1.000 which gives a more believable 9%, which split over two kegs makes it sessionable.
