Fighter Fuel Shigeri | mixing rate and steep time

Seven shop listings, three different mixing rates, and steep times that run from two days to nearly three weeks. The Fighter Fuel Shigeri concentrate can leave you hesitating with the syringe in hand. A ready-made shortfill sold under the same name adds to the confusion. Before anything goes into a bottle, it pays to know which product you are holding and which figure deserves your trust.

The Fighter Fuel Shigeri mixing rate to start from

Start at 9% concentrate in a 50/50 base, then taste after two to three days of steeping. That is the most widely published figure for Fighter Fuel Shigeri. Four of the seven listings we checked in October 2026 give it, and three of them attribute it directly to Maison Fuel, the French company that makes the range.

Treat it as a starting point rather than a law. One listing quoting 5% also claims to follow the maker, and another goes up to 15%. Starting at 9% leaves room to move in either direction, and a final tasting at around one week settles the question.

Concentrate or shortfill, two Shigeri products not to mix up

The Shigeri name covers two separate products in the Fighter Fuel range, and the 9% rate only applies to the first one.

The Shigeri concentrate comes in a 30 ml PET bottle with a safety cap and a dropper tip. It is made of flavourings and propylene glycol, contains no nicotine and is never vaped neat. Listings describe a blend of pomegranate, wild strawberries and kiwi, lifted by a cooling note.

The Shigeri e-liquid, by contrast, is sold notably as a 100 ml nicotine-free shortfill at 30/70, in a 120 ml bottle with room for two nic shots. Two 10 ml shots at 20 mg/ml bring the whole bottle to roughly 3.3 mg/ml. That liquid is already flavoured, so the only thing you add is nicotine.

Why the Fighter Fuel Shigeri listings disagree

For one and the same 30 ml bottle, here are the rate and steep time shown by each shop in October 2026, unrounded.

Listing checked	Rate quoted	Steep quoted
Le Petit Vapoteur	9% at 50/50	2 to 3 days
Arômes et Liquides	9% at 50/50	2 to 3 days
Vapoclope	9% at 50/50	2 to 3 days (2 to 5 days on its spec sheet)
Taklope	9% at 50/50 (5% at 70/30, 14% at 30/70)	3 to 7 days
Création Vap	5% at 50/50 (7% at 70/30, 10% at max VG)	1 week
Arsène Valentin	5%, ratio not stated	12 days
Eliquid & Co	15% at 50/50	15 to 20 days

The same tension runs through the published figures for the Red Astaire concentrate.

Two ratio grids that contradict each other

Two listings also publish rates for other bases. The first follows the usual logic, more concentrate as the glycerine share rises. The second asks for more at 70/30 than at 50/50, which runs against that behaviour and is reason enough to set ready-made grids aside for this concentrate.

What the gap between 5 and 15% weighs

In a 50 ml mix, 5% means 2.5 ml of concentrate and 15% means 7.5 ml, three times as much. That is no longer a matter of taste, it is a different recipe. At 4.5 ml, the 9% rate sits between the two.

How long to steep a Fighter Fuel Shigeri mix

Steeping gives the flavour molecules time to spread evenly through the base. The make-up of this concentrate explains part of the gap between listings.

The cooling note comes through almost at once, while the pomegranate and wild strawberry need a few days to blend in. Tasting too early gives a liquid that is mostly cool and thin on fruit, and the rate is not to blame. The higher the vegetable glycerine content of the base, the longer the steep, a principle several listings repeat.

A three-date tasting plan at day 2, day 5 and day 7

Rather than picking one duration from the table, mix a single 10 ml bottle at 9% and taste it on three dates, noting the balance between coolness and fruit each time. It is the same spaced tasting discipline we apply to the Heisenberg concentrate.

On day 2, check whether the coolness still hides the fruit.
On day 5, see whether the pomegranate and strawberry stand out from the kiwi.
On day 7, compare with your day 5 note.

If nothing changes between day 5 and day 7, there is no point waiting the fifteen to twenty days of the most cautious listing. If it is still moving, give it another week before you touch the rate.

Adjusting the rate for a base other than 50/50

The 9% figure is given for a 50/50 base, and several listings say it needs adjusting for other ratios. A glycerine-rich base, thicker and sweeter, generally needs a higher rate for the same perceived intensity. Our guide to the DIY base and its PG/VG ratio explains why.

With no reliable grid to lean on, work in steps. At 30/70, start at 9% and go up one point at a time if the fruit feels muffled. At 70/30, try 7 or 8% for the first batch instead.

Mixing 10, 30 or 50 ml, the sums

The sum is always worked on the final volume, concentrate included. At 9%, these are the volumes to measure.

For 10 ml, 0.9 ml of concentrate and 9.1 ml of base.
For 30 ml, 2.7 ml of concentrate and 27.3 ml of base.
For 50 ml, 4.5 ml of concentrate and 45.5 ml of base.

Measure with a graduated syringe rather than by the drop, because the number of drops per millilitre varies with the tip and the viscosity. Retailers also advise gloves, safety glasses and a label giving the name and rate on every bottle.

Adding nic shots

A nic shot takes up volume, so it comes out of the base, never out of the concentrate. For 50 ml at 3 mg/ml you need 150 mg of nicotine, which is 7.5 ml of shot at 20 mg/ml. The recipe becomes 4.5 ml of concentrate, 7.5 ml of shot and 38 ml of base.

In the UK, nicotine-containing e-liquid is capped at 20 mg/ml and sold in bottles of 10 ml at most, and a refillable tank cannot hold more than 2 ml. The shot’s own PG/VG ratio also shifts the final balance slightly.

Dark Shigeri and Bloody Shigeri, other recipes under the same name

One misread bottle is enough to throw a rate off. Dark Shigeri adds blackcurrant to the pomegranate and strawberry, and it also exists as a 30 ml concentrate and as a 100 ml shortfill. Bloody Shigeri swaps the kiwi for dragon fruit and comes as a 100 ml shortfill. These variants carry their own instructions, and the 9% rate only holds for the original Shigeri.

FAQ

Does the Shigeri concentrate contain nicotine?

No. Its make-up is limited to flavourings and propylene glycol. Any nicotine comes only from nic shots or from a base that already contains it, added at the mixing stage.

Can Shigeri be paired with another concentrate?

Yes, but the 9% rate no longer applies as it stands. Each added concentrate takes its share of the flavour volume, and both rates need lowering to avoid a saturated mix. Try any such pairing on 10 ml before scaling up.

Does a DIY mix taste the same as the Shigeri shortfill?

Listings describe the same fruit, but the result will not be identical. The shortfill is built at 30/70 with a rate chosen by the maker, while a home mix at 9% in a 50/50 base carries the flavour differently.

Which bottle should I mix in?

An empty bottle, graduated if possible, holding at least the volume you want. Pouring the concentrate straight into the base bottle rules out any accurate rate, because the amount of base is no longer under control.

Can an overloaded Shigeri mix be rescued?

Yes, by topping it up with plain base until the rate is back near 9%. Steeping does not reduce the amount of flavouring present, it only evens it out.

Fighter Fuel Shigeri, one starting figure and three tastings

Keep 9% in a 50/50 base and a first tasting after two or three days, then judge the result over three tastings rather than on a single listing. The 5 and 15% figures exist, but they lack any consensus.

The rest is bench discipline, a sum worked on the final volume and a label on every bottle. That habit works for every concentrate, including the one inside a ready-assembled DIY kit, and it lets you judge a Fighter Fuel Shigeri mix on the evidence rather than on someone else’s number.
