hi to all. i had a silly thought. what makes , say, your specific gravity higher at the beginning of fermentation? is it the sugar, the fruit juice or both ? i started wondering if you can raise s.g. before fermentation by adding sugar or more juice and does this thinking have a place in winemaking? best regards, lucas
SG is a measure of the density of the solution. Density is how much a given volume weighs. To get a higher SG you need to increase the weight of that volume. To do that you have to add something more dense. Adding fruit juice that is 1.060 toa solution that is 1.070 will not increase the gravity. What you have to do is dissolve more stuff in it or blend in a higher gravity solution.
So yeah, you can add more sugar to it and get a higher sg.
In the future it would be nice if you left that url out of your posts. We are not here to bump your google rating and make you money through google ads.
Solids dissolved in water tend to raise its s.g. -- it gets heavier for the same volume 'cause there's more "stuff" in it. A cup of salt will raise the s.g. of a quart of water -- but that will never ferment. Its usually assumed, for winemaking purposes, that fruit juice, either pressed from grapes or bought from the store, has a higher s.g. than water only because of its sugar content. Yes there's other things dissolved in it, but they have a negligable effect on s.g. You can use sugar, or more sugary juices, or frozen juice concentrate, or cans of grape juice concentrate bought from the wine making supply store to get the s.g. to where you want it.
You have already been given the answer to your question but there is a relationship between the wine style and the SG. A Riesling at 14 % alcohol may taste hot where a Cab at the same alcohol is not. The yeast used also matters, some don't mind a lot of alcohol, some strangle in it.
Sugar makes up around 98% of the disolved solids in clean must; the others for the most part are the acids and tannin in reds and they stay behind for the most part too.

hi, thank you for your answers.i understand now. im retired from the marines. the url was is a tribute to the men who served our country. i make nothing off of it.sorry it offended you . best regards,lucas
Well I didn not go to the URL. And I apologize if I was crabby about it.
If you are not trying to make money off of it that is another matter. I just get tired of guys trying to use the groups as a way to increase hits on their sites. That is why I do not go to links I see listed in messages. Again, i apologize for being an ass about it.
no need for apolagy mr droopy, but accepted. best regards, lucas
Suggestion regarding your link so everyone knows what you intend it for: Work it into a genuine .sig line, something like ...
