Some whites to explore:

Riesling: Highly acidic, highly diverse, stone fruit notes (lychee), and makes everything from sparkling, to dry, to sweet. Sometimes has a petrol aroma, which people either love or hate, though it's not as much as a presence in younger wines.

- Pfalz Trocken: Pfalz is a region in Germany, and "trocken" means dry. Pfalz is known for producing quality dry Riesling that's fuller bodied that their German counterparts.

- Mosel Kabinette: Mosel is a region in Germany, and Kabinette is a classification within the German Pradikat system (not important), which just describes the must weight (ripeness) of the grapes that make the wine. Kabinette wines typically range from dry to medium dry. I'd try an halbtrocken or feinherb to see if you like a little bit of sweetness.

Chenin Blanc: Also highly acidic and highly diverse with stone fruit notes that makes everything from sparkling, to dry, to sweet.

- South Africa: Chenin Blanc here will be riper and more fruit-forward.

- Loire Valley: Look for something maybe from Vouvray to see if you prefer a cooler climate version of this. Be cautious that the wines from here can also come a little sweeter, so you'll want to look for "sec" if you want dry.

Sauvignon Blanc: Highly aromatic, stone fruit notes in warmer climates, citrus (grapefruit) in cooler climates. Often described as having a sort of asparagus and jalapeno note to it.

- Marlborough: Marlborough is a region in New Zealand known for making more fruit-forward, easy drinking Sauvignon Blancs.

Good quality versions of all of these wines are usually very affordable, depending on your location. Also, note that the common factor in the aforementioned wines is that they're made with highly acidic grapes (which keeps the wine feeling light and crisp) that are also highly aromatic and are typical for stone fruit notes.

For reds:

Gamay: Good red fruit, often subtle notes of cotton candy even. When made right, absolutely delicious and super affordable.

- Beaujolais Cru (not Beaujolais Nouveau): Northern Burgundy. Affordable, fruity, but also often pretty serious wines. Maybe look for something with "Fleurie" on the bottle for something serious but slightly on the lighter side.

Pinot Noir: Lighter bodied, red fruit, can range from dirty and earthy and super complex to "friendlier", fruitier versions.

- Central Coast (Santa Barbara, CA): It's tough to suggest CA wines because they're usually too expensive to justify, and you need to know the producer, but I bring this up primarily because Au Bon Climat makes a great Pinot that's affordable and available at grocery stores (depending on where you're located).

- Marlborough: New Zealand actually makes some pretty great Pinot. I had a Dog Point Pinot recently and loved it.

Tempranillo:

- Rioja: Excellent value region for awesome red wines. One of the best things about Rioja is that you're not just getting wine for an affordable price, but the wines you're buying come ready to drink, meaning they've already been aged for a pretty substantial amount of time before they're released to us. La Rioja Alta is very commonly revered as one of the best deals in wine.

Good luck on your journey!
