It's one of the first questions people ask before trying a simmer pot for the first time — and a fair one, since it directly affects whether it's actually worth it compared to a candle.
How long one simmer session lasts
A single simmer typically runs 2-4 hours on low heat, filling a room steadily the whole time. Unlike a candle, the scent doesn't fade evenly toward the end — it stays fairly consistent as long as there's water in the pot.
How many times you can reuse a blend
This is the part most people don't expect: a single batch of ingredients can usually be simmered 1-2 additional times. Just add fresh water once the original simmer is done, and the blend releases scent again, though slightly softer each round.
What actually ends a blend's life
The ingredients themselves — citrus, herbs, spices — will start to break down and lose potency after 2-3 total simmers. At that point, it's time for a fresh batch rather than more water.
How this compares to a candle, cost-wise
A candle burns once, start to finish, and it's gone. A simmer blend, reused 2-3 times, effectively stretches further than its per-use price suggests — you're getting multiple sessions out of one batch rather than one continuous burn.
A few tips to make a blend last longer
- Keep the heat low — a rolling boil burns through water (and ingredients) faster than it needs to.
- Top off water as it evaporates instead of letting the pot run dry.
- Store unused portions in the fridge between uses if you're not simmering it all in one sitting.
