It’s quite simple, really. Lighter foods such as light appetizers and dinner foods such as fish and chicken deserve a lighter wine. So think white wines.
Heavier dinner foods such as steak and potatoes go great with red wines.
The beauty of wine is that there are so many to choose from, and it takes time to find ones you like! Perhaps attend a food & wine event near you to sample different wines. Best of all, the wine representatives will be there to share their knowledge with you and help you learn about wine. Cheers!
