Alfaliquid Peach, which version suits your draw

On the shelf, one bottle of Alfaliquid Peach looks much like the next. Same name, same 10 ml format, same flavour on the label. What differs sits in small print, a base ratio and a nicotine strength, and those two figures behave very differently in a tight pod and in an open tank. Picking this liquid without thinking about how you inhale is a little like buying a recipe without knowing which oven it will go into.

Which Alfaliquid Peach for which draw

The Alfaliquid Peach from the brand’s Boissons (drinks) range comes in two bases. The 70/30 version, rich in propylene glycol (PG), is aimed at the tight mouth-to-lung (MTL) draw. Its 50/50 version, with more vegetable glycerine (VG), suits looser draws, from an airy MTL to a restricted direct lung (RDL) draw.

The manufacturer draws the line by coil resistance. Above 0.8 ohm for a standard coil, or above 0.6 ohm for a mesh coil, it recommends the 70/30. Below those thresholds, it points towards the 50/50.

Style of draw	Typical coil	Suggested base	Strengths offered (mg/ml)
Tight MTL	above 0.8 ohm (standard)	70/30	0, 3, 6, 12, 16
Airy MTL	around the threshold, mesh above 0.6 ohm	70/30	0, 3, 6, 12, 16
RDL	below 0.8 ohm (standard) or 0.6 ohm (mesh)	50/50	0, 3, 6, 12

The table already shows one limit. The 16 mg/ml strength only exists in 70/30, so the highest strength in the range is missing from the base meant for open draws.

Tight MTL, home ground for the 70/30

Mouth-to-lung vaping holds the vapour in the mouth before inhaling, through a narrow draw close to that of a cigarette. Our guide to MTL vaping and the tight draw covers the technique in detail. This style relies on higher resistance coils and modest wattage, which is exactly where a thinner base earns its place.

Why a thin base suits a higher resistance coil

A coil of 1 ohm or more heats only a little liquid with each puff, through narrow wicking ports. A PG-rich liquid flows quickly through those ports and re-soaks the cotton between puffs. Too thick a base can leave the wick drying out instead, with a burnt taste as the result.

PG also carries flavour more sharply. With peach, that clarity matters, because a delicate fruit is easily lost in dense vapour.

Strengths in the 70/30

The 70/30 covers the whole scale of the range, from 0 to 16 mg/ml. In the UK, nicotine-containing e-liquid is capped at 20 mg/ml under the Tobacco and Related Products Regulations 2016, so every strength of this Peach sits under that ceiling.

Airy MTL and RDL, where the 50/50 takes over

As soon as the airflow opens and the coil resistance drops, the liquid is used faster and the wick has to keep up. Our article on DTL and RDL vaping describes these airier draws. The 50/50 base of the Alfaliquid Peach answers that change of pace.

A thicker option for low resistance coils

On a coil of 0.6 ohm or less, the wicking ports are wider. A very thin base passes through them faster than the coil can vaporise it, and the surplus can leak through the airflow. Being more viscous, the 50/50 slows that flow and keeps pace with the heat.

The airy MTL case

In between, an airy MTL draw sits right on the threshold. A 0.8 ohm mesh pod stays above the 0.6 ohm limit the manufacturer sets for mesh, so it remains 70/30 territory. The same value in a standard coil sits exactly on the line, and the 50/50 becomes a sensible choice if the pod tends to weep.

Nicotine strength and liquid used, draw by draw

The leaflet supplied with Alfaliquid’s 10 ml bottles states that a tank filled with 1 ml of liquid delivers the quantity of nicotine shown on the label. Strength is therefore expressed per millilitre, and it is the volume vaporised that changes what each puff carries.

What a looser draw changes

An RDL draw vaporises more liquid than a tight MTL draw over the same number of puffs. Common practice therefore pairs open draws with lower strengths, which fits with a 50/50 version that stops at 12 mg/ml. Our comparison of nic salts and freebase nicotine looks at the same link between draw and strength.

A simple sum for comparison

A 2 ml pod filled at 6 mg/ml holds as much nicotine as a 1 ml tank at 12 mg/ml. That ratio helps when comparing two devices of different capacity without changing liquid.

Filling a pod from the 10 ml bottle

The bottle of Alfaliquid Peach is designed for slow filling, and a few instructions that shop listings rarely repeat help avoid flooding a pod.

A dropper that does not run on its own

The bottle is made of low-density polyethylene, and its dropper tip lets through no more than 20 drops per minute when held upright without pressure, at a temperature of 18 °C plus or minus 5 °C. In practice you squeeze the bottle gently to fill, which lets you add the liquid drop by drop and stop below the fill line.

Shake, fill, let it soak

Shake the bottle well before use. Once the pod is filled, give the cotton a few minutes to soak before the first puff, especially with a new coil. The wait matters more with the 50/50, which takes longer to work into the wick.

Keep the bottle closed and away from light, within the same 13 to 23 °C range. Direct sunlight is best avoided. In the UK, refillable tanks and pods are limited to 2 ml, so a 10 ml bottle fills a full-size pod five times.

Wattage and airflow to keep the peach clear

A fruit recipe copes poorly with overheating. Past the top of the coil’s range, the peach loses definition and the vapour turns hot. Set the wattage within the range printed on the coil, ideally starting at the bottom of it.

Then adjust the airflow. On MTL, an almost closed airflow concentrates the flavour. On RDL, a wider opening cools the vapour and lets the wattage climb without scorching. Our article on picking the right coil resistance explains how each value sets that frame.

One last pointer is worth keeping. If a pod gurgles with the 70/30 on a low resistance coil, the cause is usually the base rather than the device.

FAQ

A few practical questions about this bottle, beyond the choice of base and draw.

Can you add water to stretch the Peach?

No. The recipe is sold ready to vape, and the manufacturer makes no provision for adding anything to the 10 ml bottle. Diluting it with water would change both the base and the strength, with no guidance from the brand.

Can you mix the 70/30 and the 50/50 in one pod?

You can, since both versions share the same recipe. In equal volumes, the blend gives a base close to 60/40. It is still better to empty the pod before switching versions, so you know what you are vaping.

Who makes Alfaliquid Peach?

The liquid is made and bottled in France by Gaiatrend, in Rohrbach-lès-Bitche in the Moselle. The brand also highlights the Origine France Garantie label and ISO 9001 certification, with a batch number on every bottle.

Should you empty the pod before moving to the Peach?

Ideally, yes. The cotton holds on to part of the previous flavour for several fills, and a delicate peach is easily masked by a heavier recipe. A fresh coil gives the cleanest taste.

Does the 50/50 work in a tight MTL pod?

It can, but the thicker base may struggle to feed a high resistance coil quickly enough. If the flavour fades or turns dry after several quick puffs, the 70/30 is the better match for that pod.

Alfaliquid Peach, a base that follows the draw

The recipe stays the same across both versions, only the base changes. Higher resistance coils and tight draws call for the 70/30, with strengths up to 16 mg/ml. The 50/50 goes with low resistance coils and open draws, up to 12 mg/ml.

Before choosing an Alfaliquid Peach, read the value of your coil and compare it with the manufacturer’s threshold. That idea runs through all of Inhale Zone, comfort in vaping comes from the way you inhale long before the choice of flavour.
