Wine has been enjoyed for thousands of years and is produced in many different styles around the world. From light and fruity reds to rich and full-bodied blends, understanding common wine varieties can help you appreciate the unique characteristics that make each wine different.
One of the most widely recognised red wine varieties is Merlot, a versatile grape known for its approachable flavour profile and smooth texture.
In this guide, we’ll explore Merlot alongside several other popular red wine varieties to help you better understand the world of wine.

A wine variety refers to the specific type of grape used to make the wine.
Each grape variety has its own characteristics, including:
- Flavour profile
- Aroma
- Acidity
- Tannin levels
- Colour
- Ageing potential
Factors such as climate, soil, winemaking techniques and ageing methods also influence the final style of the wine.

How Climate Influences Wine
Climate plays a major role in determining how a wine tastes.
Cooler Climates Often Produce:

- More subtle fruit flavours
Warmer Climates Often Produce:
- Riper fruit flavours
- Fuller body
- Higher alcohol levels
This is why the same grape variety can taste different depending on where it is grown.
Understanding Tannins
Tannins are naturally occurring compounds found in grape skins, seeds and stems.
They contribute to a wine’s structure and mouthfeel.
High-tannin wines may feel drier or firmer, while lower-tannin wines often feel softer and smoother.
Examples:
- Higher tannins: Cabernet Sauvignon, Syrah
- Medium tannins: Merlot, Malbec
- Lower tannins: Pinot Noir
Understanding Acidity
Acidity provides freshness and balance in wine.
Higher-acid wines often feel brighter and more vibrant, while lower-acid wines may feel softer and rounder.
Acidity also influences a wine’s ageing potential.
