The Black Mint Just Juice Bar Saltfill brings together the brand's signature approach to menthol with an extra-strong mint profile that's designed for all-day vaping. Available now at Grey Haze, this 40ml shortfill combines the refreshing qualities of fresh mint with an icy menthol finish, creating what many consider to be one of the more invigorating options in the Just Juice Bar range. The saltfill format means you're getting concentrated flavour in a convenient bottle size, with space left for your preferred nicotine shots if needed.

Just Juice has built their reputation around creating smooth, well-balanced e-liquids, and the Black Mint variant showcases this expertise particularly well. The mint profile here isn't just your standard cooling effect - there's depth to it that comes from blending different mint characteristics. Some users notice subtle dark fruit undertones that complement rather than compete with the primary mint flavour, though this varies depending on your setup and vaping style.

The menthol component provides that frosty finish without being overwhelming, which is often where cheaper mint e-liquids fall short. You'll get the cooling sensation without the harsh bite that can irritate your throat during longer vaping sessions, making it a standout in the Just Juice Bar range.
The saltfill format offers some practical advantages over traditional shortfills. The 40ml bottle size strikes a good balance - it's substantial enough to last most vapers a decent amount of time, but not so large that flavour degradation becomes a concern if you're someone who likes to rotate between different juices regularly.
The VG/PG ratio is optimised for versatility, working well in both MTL setups and sub-ohm devices, though you'll want to consider your coil resistance and wattage settings to get the best flavour reproduction. Adding nicotine shots is simple thanks to the extra headspace in the bottle.

Yes, the smooth mint profile makes it accessible for new vapers, though the "extra-strong" designation means it's got more intensity than milder mint options. Start with lower wattages if you're new to vaping.
The 40ml bottle typically has space for 1-2 nicotine shots, depending on your desired final strength. Adding one 18mg shot will give you approximately 3mg final nicotine strength.
The 40ml saltfill offers the same flavour profile in a more concentrated format, whilst the 100ml shortfill provides better value for heavy users who've already confirmed they enjoy this particular blend.
Absolutely, the balanced formulation works particularly well in refillable pod systems, though you might find the flavour more pronounced in devices with adjustable airflow.
Most users report consistent flavour throughout the bottle, with the mint profile remaining vibrant rather than fading like some fruit-based e-liquids can do over time.
