Glas Basix Butterscotch Reserve E-Liquid Review

Glas Basix Butterscotch Reserve sits in a narrow lane: an RY4-style tobacco base with dessert sweetness that can either feel balanced or feel cloying. I reviewed it because the mix ratio and flavor style tend to expose weak wicking, fast coil gunking, and flavor fade. Three variables shaped almost every session: sweetness buildup, how the tobacco note presents at different temperatures, and how consistent the finish stays late in the day.

What is the Glas Basix Butterscotch Reserve E-Liquid?

Glas Basix Butterscotch Reserve is a freebase e-liquid sold in a 60mL bottle with a 70% VG / 30% PG blend and nicotine options commonly listed as 0mg, 3mg, and 6mg. Flavor-wise, it’s positioned as a tobacco blend with butterscotch and caramel, often framed as an RY4-style profile. It fits adult users who want a sweet tobacco dessert and who are fine managing sweeter liquids that can darken cotton faster than bright fruit mixes.

Why choose the Glas Basix Butterscotch Reserve E-Liquid?

This works best for adult users who like RY4-style tobacco with a clear dessert edge, and who prefer restricted DL or a loose MTL where the sweetness can open up without feeling sharp. It also suits people who want a warmer, rounded exhale instead of a crisp, dry tobacco finish.

Skip it if you want an ultra-dry tobacco, if you hate caramel-style sweetness that can linger on the palate, or if you’re sensitive to the way sweet notes can thicken and feel “sticky” late in a tank. It’s also a poor fit for people chasing a tight, cigarette-like MTL with minimal aftertaste, and for anyone who needs a setup that stays clean with very light coil maintenance.

How We Tested It

We ran this over 3 days, with each tester landing around 100–300 puffs per day depending on schedule and nicotine strength. I focused on flavor accuracy, puff-to-puff consistency, airflow/draw behavior (as it relates to viscosity), throat hit, heat stability, and leak/condensation risk during refills. We used the widely listed freebase strengths (3mg and 6mg) and tracked coil darkening, sweetness buildup, and late-day flavor flattening across repeated top-offs.

Performance Scores of the Vape

Test window: 3 days, mixed short sessions and longer chains (roughly 100–300 puffs/day per tester). Scoring uses 1.0–5.0; flavor and throat hit are mostly subjective, while leaking, refill mess, and consistency were logged as observed behaviors.

Our Testing Experience

Our Testing Results

By the end of day one, the profile was already stable: butterscotch up front, caramel warmth on the exhale, and a tobacco base that didn’t vanish once the sweetness landed. The main change came from repeated heat cycles. In Marcus’s heavier sessions, the sweetness thickened and started to feel more “coating,” especially when he ran back-to-back pulls without a pause. That shift lined up with faster cotton discoloration and a slightly muted finish.

Jamal’s pattern exposed the opposite problem. Short hits kept the tobacco note a little sharper, then the aftertaste stayed longer between tasks, which he noticed while walking. I saw the cleanest balance in mid-length sessions where the coil had time to cool. Refill handling stayed tidy. I didn’t see persistent cap seepage or oily residue on the outside of the bottle, but the sweetness did punish coils faster than lighter tobaccos.

Draw Experience

Butterscotch Reserve delivered the most consistent “warm dessert tobacco” feel: butterscotch on the inhale, caramel on the exhale, and a tobacco thread that sits underneath instead of punching first. That description matches how it’s positioned in multiple listings.

For contrast, I rotated two other Basix flavors as checkpoints. Glazed Donut leaned fuller and sweeter, with less of that tobacco backbone, and it felt heavier during tight draws. Mango Tango was brighter and easier to reset between sessions, with tropical fruit notes that didn’t cling as long.

The shared takeaway across all three: Basix liquids tend to reward a slightly more open draw and a pace that avoids constant chain pulls.

Glas Basix Butterscotch Reserve E-Liquid Vs. Alternatives

Pick this if you want (1) a sweet RY4-style tobacco that stays readable, (2) a warm caramel-butterscotch finish, and (3) a high-VG blend that feels dense in mid-power use.
If you want a smoother, semi-sweet tobacco often compared to RY4, Halo Tribeca is a common reference point.
If your priority is dessert bakery with caramel accents rather than tobacco, Five Pawns Gambit sits closer to “pie” than “tobacco.”

Pro Tips for Glas Basix Butterscotch Reserve E-Liquid

• Shake the bottle for a few seconds before filling. The profile stays more even across the tank when the mix is uniform.
• Prime new cotton longer than you would for thinner blends. A 70/30 liquid can look ready, then still run dry in the center after the first warm pulls.
• Start your first tank a little cooler than your usual sweet spot. Two short sessions are enough to see how quickly the caramel note thickens at higher heat.
• Use a slightly more open draw if you keep getting a syrupy finish. A tighter pull can concentrate sweetness and make the aftertaste feel heavier.
• If the flavor starts to flatten, pause for a few minutes instead of pushing through. The profile often “resets” once the coil cools and the wick catches up.
• Wipe the fill port and the bottle tip after refills. That prevents sticky residue from collecting dust, especially if the bottle rides in a pocket or bag.
• Expect faster coil darkening than with bright fruit liquids. Build a routine: quick rinse for tanks where it helps, and earlier cotton changes for rebuildables.
• If you alternate liquids, run something brighter between tanks. Fruit profiles tend to clear the lingering caramel note faster than another dessert.
• Keep the bottle out of heat and direct light. A warm car compartment makes sweetness feel heavier and can dull the tobacco edge.
