def need to add more honey to it.
Too dry? You really need to know the current 'final' gravity to know the alcohol content, if it is fermented out.
That should give you some idea (if you know the alcohol tolerance of your yeast) of how much more sugar (honey) is required, otherwise it is a bit of a guessing game. Stopping the fermentation sometimes leads to 'sticking' of the fermentation, so is not recommended - it ideally needs to be steadily fermented out and then racked off, after clearing, to avoid the leas 'tainting' the wine. Adding too much will result in a sweet wine - maybe too sweet. I now know how much is in my demijohn (pop it on my scales) or fermenting vessel (calibrated for volume) and do an original gravity on a 'surplus' fermentation sample.
That can be added after the initial vigorous fermentation (when I only fill the demijohn to the shoulder to avoid frothing into the air lock). Any remaining 'extra' can be retained for adding after racking to keep the demijohn filled to the neck to avoid oxidation.
This way I can at least reproduce my fermentation as closely as the variable starting ingredients allow - so if it works OK this time, it should be very similar next time. I'm only a beginner at this lark and, like beekeeping, experience will follow. Just want to avoid making the same mistakes next time if it doesn't work this time.
C J J Berry (First Steps in Winemaking) who died in 2002(?) had a vast experience of wine making but most of the recipes are aimed for the beginner and not the hydrometer user. I may be fermenting at too high a temperature, according to him, as mine is about 18 degees. The beer brewers seem to prefer nearer 24 C but yeast varieties have changed and things appear more specialised these days.
