Most candles on a shelf are paraffin. Most people lighting them have no idea.

It's not a scandal — paraffin makes a perfectly good candle, and it's why candles are cheap. But if you've started reading labels, you've probably run into the soy-versus-paraffin question and a lot of strong opinions with not much behind them. Here's the honest version, including the places where soy isn't automatically the winner.

What paraffin actually is

Paraffin is a byproduct of refining petroleum. It's inexpensive, it holds a lot of fragrance and dye, and it throws scent hard the moment you walk in the room. That's the case for it.

The case against: it burns hotter and faster, it tends to produce more visible soot, and — for a lot of people — "petroleum wax melting in my living room" is reason enough to look elsewhere.

What soy is

Soy wax is made from soybean oil. It's renewable, it burns cooler and noticeably slower (so a soy candle lasts longer than a same-size paraffin one), and it burns cleaner, with less soot. Done right, it carries scent beautifully.

Soy isn't perfect, and we'd rather tell you than not. It can "frost" — a harmless white, crystalline look on the surface — because it's a natural wax. It's softer, so it needs the right vessel. And a cheaply made soy candle can have a weak cold throw (the scent before you light it). Soy is only as good as the maker.

How they compare, plainly

  • Burn time: Soy wins. Cooler, slower burn means more hours per ounce.
  • Soot: Soy runs cleaner. Less of that gray film on the jar and the wall above it.
  • Scent throw: A toss-up that comes down to craft. Paraffin throws hard out of the gate; a well-made soy candle throws true and even, all the way down.
  • Source: Soy is renewable and biodegradable. Paraffin is petroleum.
  • Price: Paraffin is cheaper to make. Soy costs more, and a real soy candle reflects it.

Where we land

We pour 100% organic soy, every batch, by hand in San Diego. Not because soy is the trendy answer — because it burns the way we want a candle to burn: slow, clean, and honest to the scent. We pair it with a hemp wick, which keeps the flame steady, and we don't cut our fragrance to stretch it.

That's the whole philosophy: fewer corners, slower burn.

If you want to see what that's like, the current batch is three scents — Blood Moon, Storm Watch, and Flannel — hand-poured in small runs. And if you're the type who reads the label first, the bundles are the easiest way to try more than one.
