Shall do. Meanwhile somehow, at some point I had some left over and put it in a small, empty, glass ketchup bottle I found at the back of the cupboard.
It has a metal twist top. Anyway I pulled that out after about 3 weeks and stuck it in the fridge. When I got it out this morning it was crystal clear and when I opened it it fizzed like a sparkling wine.
It was very nice but hard to judge the alcohol content as there was so little.
Anyway just ordered some wine making yeast. (Turns out just any old yeast will do but yeast specifically for wine is better).
Apparently if you get some muscat grapes yeast grows naturally on them and you casn cultivate your own.
Alternatively and as a backup I've asked the office girls not to wash there pussies for a couple of weeks and I'll be doing a scraping.
