yeast and sugar aid in the fermentation process that produces alcohol
Different wine tasts different in different climats because of water and soil differences which change the grapes that the wine is made of.

Sigh...there are whole sections in the bookstores devoted to this subject. But here is the simplified answer and reasons.
Sugar and yeast are required for fermentation, (plus water and the right temperature). Without fermentation, you will be just drinking grape juice, more or less. Sweet, simple, without alcohol and very volatile. Sugar is food for the yeast and yeast turns sugar into alcohol and CO2 plus a few other minor things.
In the old days, they do not add sugar nor yeast artificially to make wine. The sugar is already in the juice and the yeast is in the air. Nowadays, less is left to nature so sugar is added sometimes and the yeast is selected to insure successful and timely fermentation in a controlled manner.
Climate affects the length of growing period, harvest & growing temperatures, rain fall and the total amount of sunshine during the growth period. These are just a few of the key factors. In the end, different climates turn out grapes with different sugar and acid levels, amongst other things, which will determine the character of the end product.
Bottom line is, wine making is like playing golf, no two shots are exactly the same even given all "the same conditions". There are just far too many hidden variables to ever have the exact same results twice. It's the one that can produce the best most often that will be holding the trophy.
So cheers !

If you are talking about the wine served in a good restaurant -- i.e. 'proper wine' made from grapes rather than home made wines, then the answer to your question is that the reason that grapes are used to make wine is that they contain ALL that is necessary to make wine.
Wine is the fermented juice of grapes. The definition of fermentation is the conversion of sugars into alcohol by the action of yeast. Ripe grapes contain sugars in their juice, and naturally have yeasts on their skins.
Most wineries use commercially yeasts instead of the 'wild' yeasts to do the femebation as they are more reliable, but sugar is rarely added (known as 'chaptalisation', it happens in northern climes in bad vintages to raise alcohol level when the grapes aren't ripe enough.
Why wines taste differently from thesame grape varieties grwon in different places is one of the great delights of wine. Much is the effect of the winemaker and the clones of grape varieties used, when the grapes are picked, how ripe they are, how many grapes are produced by acre -- well the parameters are endless. Underlying it all is something the French call 'terroir' -- the unique combination of soil, land and weather - the rain and sun, heat and cold.
Start studying, taste all you possibly can. Its a tremendous hobby and that is veryrewarding. And you'll never ever know it all :)

The number one reason would have to be pH. The soil in different areas has different PH hence the difference in the type of wine an area it produces. The reason why sugar and yeast are used to make wine is to speed up the fermentation process. Otherwise it would take longer to make a bottle of wine.

well all of the above. sugar acts as a food for yeast which in turn converts sugar into alcohol but irony is the same yeast is killed by the alcohol it has so hard worked to produce. the sweetness and dryness of the wine depends on the time the yeast was allowed to function. the difference comes due to terrior(which r combined factors of soil, climate, sun, water) and pruning methods. in addition the taste of wine depends on its aging process as well. thus even neighbouring vineyards using the same grapes willl produce diff wines.

The sugar feeds the yeast, which ferments the grapes.
A grape is only as good as the water, soil and sunshine that nourish it. Different climate, different grape, different wine.
I'm not a vintner, but I hope that helps a bit.

Yeast ferments it and sugar activates the yeast and adds flavor.

very simple: yeast eats sugar and poops alcohol. any moonshiner knows that!
