I believe for most people alcohol is an acquired taste.
Generally speaking one finds a wine or combination of alcohol that tastes sweet or seems devoid of alcohol and then then they gradually expand their tastes.
A novice drinker may think wine is wine or beer is beer.
However once one acquires a taste they have their favorites as well as those they continue to dislike. I didn't start appreciating Pinot Noir wine until I had a bottle of Wild Horse in a restaurant. I also enjoyed their Merlot. The winery, it's location, & year makes a difference.
It was a similar experience for me with Chardonnay. I was at a company Christmas party that was serving Cakebread Cellars Chardonnay.
Another factor has to do with whatever type of food you're having. Certain wines go better with beef, fish, chicken...etc. Different years also matter. White wine is usually chilled and red usually is not.
You might enjoy going to a wine tasting event with a group of friends.
If you live near a Costco or Sam's you may notice in their wine departments a (point scoring system) by the various wines along with a blurb describing the wine's taste and aroma along with other attributes for that bottled year.
Naturally most of their wines be in the high 80s or above.
Wine Spectator's 100-Point Scale:
95-100 -- Classic; a great wine
90-94 -- Outstanding; superior character and style
80-89 -- Good to very good; wine with special qualities
70-79 -- Average; drinkable wine that may have minor flaws
60-69 -- Below average; drinkable but not recommended
50-59 -- Poor; undrinkable, not recommended
You may even surprise yourself a like a wine that is not rated all that high or in the $10-$12 per bottle price range like Robert Mondavi Private Selection Central Coast Pinot Grigio.
It may come down to your family's taste in wine is different from your own or you may never find a wine you do enjoy. Some people are really into having scotch, vodka, beers, or assorted cocktails with meals. Each type of alcohol has it's own sophisticated followers or enthusiasts.
