What Makes a Candle Smell Stronger?

Uncovering the Secrets Behind Powerful Fragrance Throw and How to Choose Potent Scents

A beautifully scented candle does more than just light up a room—it transforms it. Whether you're seeking a cozy ambiance or a refreshing vibe, the strength of a candle's aroma plays a crucial role. But what exactly makes a candle smell stronger? Let’s explore the science and artistry behind fragrance throw and how to choose candles that truly make an impact.

Understanding Fragrance Throw: Hot vs. Cold

To begin, it’s essential to understand the two types of fragrance throw:

• Cold Throw refers to the scent a candle emits when it’s unlit.

• Hot Throw is the scent it releases once the wax melts and the flame is burning.

Both are important, but a strong hot throw is usually the hallmark of a high-quality candle. Now, let’s dive into the key factors that influence how strong your candle smells.

1. Wax Type Matters

First and foremost, the wax used in a candle significantly affects fragrance performance. Different waxes hold and release scent oils in distinct ways:

• Soy wax is popular for its clean burn and eco-friendly appeal, but it tends to offer a more subtle throw.

• Paraffin wax, while not as natural, is excellent at delivering powerful scent—especially in hot throw.

• Coconut and beeswax blends provide a luxurious alternative, often yielding a rich, smooth aroma with excellent performance.

For the best results, look for candles with a wax blend that optimizes scent delivery while aligning with your values.

2. Fragrance Oil Load

The amount of fragrance oil added to the wax—known as the fragrance load—is another determining factor. Most quality candles contain 6–10% fragrance oil by weight, which is often the optimal range for a strong throw. However, more isn’t always better. If the oil load exceeds the wax’s ability to bind it, the scent can become distorted or weak over time.

Premium candle brands, like William West Candles, master the balance between high fragrance load and optimal performance to ensure a memorable scent experience every time.

3. Proper Curing Time

Curing allows the wax and fragrance oils to bond completely, which improves the scent throw once the candle is burned. As a general rule, soy and natural wax candles require at least 1–2 weeks to cure, whereas paraffin candles cure faster. Skipping or shortening the curing time often leads to a muted aroma, especially in cold throw.

4. Quality of Fragrance Oils

Not all scent oils are created equal. Synthetic oils can sometimes smell overpowering but lack depth, while essential oils may offer authenticity but fade quickly. The strongest candles often use a blend of high-grade fragrance oils engineered for longevity and richness.

When choosing candles, opt for brands that invest in premium, phthalate-free fragrances—your nose (and health) will thank you.

5. Wick Size and Placement

A candle’s wick acts as the engine that fuels the fragrance release. A wick that’s too small won’t produce enough heat to melt the wax evenly, weakening the hot throw. Conversely, a wick that’s too large can cause tunneling or burn the wax too fast.

Well-made candles feature strategically sized and placed wicks, often using cotton or wood for a clean, steady burn. Multi-wick candles can enhance fragrance distribution in larger spaces.

6. Container Size and Room Placement

The size of the candle and the room it's in both affect perceived strength. A single-wick candle in a large, open-concept room may not deliver the same intensity as it would in a smaller, enclosed space.

Therefore, match the candle’s size to the room where it will be used. For stronger scent, go for larger candles with multiple wicks in open areas or cluster smaller candles for greater impact.

7. Burn Technique and Maintenance

How you burn your candle matters, too. For maximum scent throw:

• Burn for at least 2–3 hours on the first use to form a full melt pool.

• Trim the wick to 1/4 inch before each burn to prevent soot and uneven melting.

• Keep the candle away from drafts to ensure even burning.

These small practices enhance both fragrance and longevity.

Choose Candles That Speak to the Senses

When you're shopping for a truly aromatic candle, don’t settle for less. Pay attention to wax composition, fragrance oil quality, wick design, and overall craftsmanship. All of these elements come together to create a candle that doesn’t just burn—it performs.
