Absolutely! I taste everything! I had to postpone probably 6 wines till (hopefully) this year because of poor flavor.I'm going to chime in with some unsolicited advice. It is always important to remember quality of ingredients. Don't go and get a shelf stable litre of orange juice and expect it to make a good wine.
I made this mistake early with my dandelion wine. The recipe called for an orange and I never accounted for my personal taste, I just went to the store and grabbed a large orange. Well, I would never choose to eat one, so why I thought I would like it in wine is beyond me. I like Mandarin's and clementine's, adding your every day large orange is also equal to at least 2 of the smaller oranges, so at last tasting I had a dominant orange flavor that I didn't like.
Just something to keep in mind. Use what tastes best to you, and the highest quality juice is going to come from fresh oranges. Squeeze them yourself.
After flavor organic is the next most important to me. I've read some oranges had up to 15 different pesticides identified. To think they all wash away is naive as far as I'm concerned.
