I Want a Candle with 50% Vanilla, 30% Coffee and 20% Caramel Fragrance Blend — How Do I Convert That Blend into Grams for a 1 Kg Wax Batch?

The conversion, both ways

A blend ratio is a recipe for one thing: the fragrance. It has to be combined with a second decision, the load, before it turns into grams. CSI's convention, used throughout this series, is that load is the share of the finished candle that is fragrance. The ratio then divides that fragrance: each component = blend grams × its share. The blending hub sets out the rule. This page applies it to one specific batch: 1 kg, 8%, 50/30/20.

The phrase "1 kg wax batch" is where the confusion starts. Some makers mean they have a 1 kg bag of wax and will use all of it. Others mean they want 1 kg of candle at the end. The two need different amounts of fragrance, and both are legitimate. The table gives both, plus the shortcut many people take without realising it changes the load.

Reading A uses the fixed-wax formula: blend = wax × load ÷ (1 − load). It is the right one when the wax weight is the thing you are not going to change, for example a single 1 kg bag of Luxury Soy Wax Chunks. The batch comes out at 1,086.96 g, which is 5.43 candles of 200 g: five full candles and 86.96 g over. Pour the extra as a test candle or a wax-melt sample; do not stretch it across the five jars, or each candle will be heavier than its label.

Reading B uses the finished-weight formula directly: blend = 1,000 × 0.08 = 80 g, wax = 920 g. It is the tidier choice when you are filling a known number of jars, because five 200 g candles is exactly 1,000 g. You will have 80 g of Chunks left in the bag for the next batch.

Reading C is the one to watch. Stirring 80 g of blend into a full kilo of wax is common, and the candle it makes may be perfectly good. It is just a 7.41% candle, not an 8% one. That matters when you compare it against a test you believe was 8%, or when you scale it up. 80 g or 86.96 g? covers the two conventions in detail, and the 10 kg version shows how the gap grows at production scale.

There is no CSI oil called Caramel

On the 24 September 2026 pull, the Fragrance Oils collection lists 93 products and none of them is called Caramel, Salted Caramel or Toffee. We could point you at the nearest gourmand and call it caramel. We are not going to, because you would be building a candle description on our guess about your nose. What you can do is test candidate oils in the 20% slot, judged as what they are, and decide whether the finished candle meets your brief. Two candidates are in stock in 15 g testers:

The control matters more than it looks. A third oil at 20% of an 8% blend is only 1.6% of the candle. It may change the character noticeably, or it may barely register once the candle is burning. Without a candle that leaves it out, you cannot tell which. Why two good oils can make a weak blend explains how dilution works inside a blend, and evaluating blends in wax explains why the bottle cannot settle this for you.

Choosing the vanilla and the coffee

The two anchor slots are simpler, because CSI lists oils that are named for them. For the vanilla slot, Dark Vanilla and Vanilla Bean are priced identically on the pull date: ₹130.00 for 15 g, ₹410.00 for 50 g, ₹790.00 for 100 g and ₹7,646.00 for 1 kg. Choosing between them is a matter of smelling both in wax. For the coffee slot, Roasted Coffee is the value choice at ₹93.22 for 15 g and ₹3.90 a gram at 100 g. Coffee Vanilla Tobacco is a richer, multi-note alternative from ₹449.00 for 50 g.

One caution on Coffee Vanilla Tobacco. Its name tells you it is already a multi-note profile, and it carries vanilla in the title. Putting it in the 30% coffee slot is not a like-for-like swap; it is a different recipe, and the vanilla-to-coffee balance you designed will move. That can be a good thing. Just test it as its own candle rather than assuming 50/30/20 still describes the result. If vanilla ends up dominating after cure, the coffee-vanilla cure-shift page is the next read.

Test the recipe before the kilo

Before you commit a kilo of wax and about 87 g of oil, pour three 200 g test candles on the same day from the same wax: one for each caramel-slot candidate and one control. Every candle is 8% of 200 g, so 16 g of blend and 184 g of wax. Only the recipe changes.

The three candles use 26.00 g of vanilla and 15.60 g of coffee, so 15 g testers of the anchors will not cover them. For the vanilla, compare the routes honestly: a 50 g (₹410.00) covers the test but leaves only 24.00 g against the batch's 43.48 g, so you would buy again. The 100 g (₹790.00, ₹7.90 a gram) covers the test and the reading-A batch with 30.52 g to spare. The coffee needs 15.60 g, just over a tester, so the 50 g (₹230.00) is the right size and carries into the batch. The caramel-slot candidates only need 3.20 g each, so a 15 g tester of each is ample.

What the batch costs

Costing the 1 kg batch (reading A) with Chocolate Fudge in the 20% slot and every oil at its 50 g rate: Dark Vanilla ₹8.20 a gram, Roasted Coffee ₹4.60 and Chocolate Fudge ₹3.96. The blend averages ₹6.27 a gram.

Per 200 g candle, the same blend is 16 g at ₹6.27 a gram, which is ₹100.37 of fragrance. Add 184 g of Chunks (₹110.22), an Eco Thin C1 wick (₹5.90) and a White Matte Glass Jar (₹70.80) and the material cost is ₹287.28, excluding labour, packaging, freight and GST. With Cinnamon Vanilla in the 20% slot the blend averages ₹6.57 a gram, ₹4.68 more per candle. Vanilla drives the cost: at ₹8.20 a gram it is half the blend by weight and 65.4% of the blend's cost.

Rolling shopping list

The list below is built so the test oils roll straight into the 1 kg batch. You buy once for the test, pour three candles, and top up only what the winning recipe still needs. CSI does not sell a blending kit, sample set or combo; you build it from single oils.

The test uses 552 g of the first kilo of wax, leaving 448 g for extra test pours. After the test, the vanilla and coffee already cover the reading-A batch. What is left to buy is a fresh 1 kg bag of wax and a 15 g top-up of the winning third oil, because the tester has 11.80 g left against the 17.39 g the batch needs: ₹692.22 with Chocolate Fudge or ₹705.20 with Cinnamon Vanilla. Reading B (80 g of blend, 920 g of wax) needs 16.00 g of the third oil, still more than the 11.80 g left, so the same 15 g top-up applies. If the control wins and you drop the third slot, you need no top-up oil at all. Plan the usual 3–5% extra for pour loss as a working assumption.
