Most candles smell wonderful in the shop and of nothing at home. On wax, wicks, and what to look for if you want a candle worth lighting.
There is a particular disappointment in a candle that smells of nothing. You buy it because the shop smelled of cedar and smoke; you light it at home and get a faint suggestion of warm air. The culprit is rarely the fragrance itself. It is everything around it.
Wax matters more than the label suggests
Soy, rapeseed and coconut waxes burn slowly and carry scent well. Paraffin burns hot and fast and can smell faintly of kerosene at the end. A blend is fine — many excellent candles are blends — but ask what is in it, and be wary of a candle that will not say. Natural waxes also burn more evenly, which means less wasted wax at the sides of the jar.
Scent throw is about temperature, not promises
A candle's scent is released by heat, so a wide jar with a small wick may never get hot enough to fill a room. Look for a wick-to-jar ratio that feels generous, and give the candle time: the first burn should last long enough to melt the whole top layer, or you will get a tunnel and a candle that only ever smells in the middle.
Read the ingredients, not the poetry
“Amber oud, smoked vanilla, a whisper of leather” tells you what the perfumer was aiming for. What matters more: is the fragrance a blend of essential oils and aroma compounds, or entirely synthetic? Neither is automatically bad, but natural blends tend to smell softer and develop as they burn. A candle that lists its notes honestly is usually a candle worth buying.
Burn it properly
Trim the wick to five millimetres before every burn. Keep the candle away from draughts, which make it burn unevenly. Never burn longer than four hours at a stretch. And when the wax is gone, keep the jar — a good vessel is half the reason to buy well in the first place.
A candle is a small luxury, and it should earn its place. Choose one that smells like something, burns like something, and makes the room feel finished when you put the match down.
