Best DIY E-liquid Concentrate Brands UK 2026

DIY e-liquid mixing in the UK is dominated by five or six concentrate brands that carry virtually every recipe you’ll find online. With the October 2026 UK vape tax making pre-made e-liquid significantly more expensive, DIY is about to become the default approach for serious UK vapers. Below are the best DIY e-liquid flavour concentrate brands available in the UK, ranked by quality, UK retailer availability and value.

Quick Verdict

• Best all-rounder: Capella — huge range, cheap, every UK DIY retailer stocks them
• Best for complex flavours: FlavourArt (FA) — Italian-made, refined, used in premium commercial e-liquids
• Best potency/value: Inawera (INW) — Polish, potent, works at 1–3% in most recipes
• Best budget range: FlavorWest (FW) — huge catalogue, consistently under £2 a 10ml
• Best for authentic flavour character: The Flavor Apprentice (TPA/TFA) — the industry benchmark

1. Capella

Country: USA · Typical UK price: £1.49–£4 per 10ml · Recommended mix %: 5–20% depending on flavour

Capella is the UK DIY default — virtually every UK concentrate retailer (Vapable, Vapour Depot, Prime Vapes, Alchemists Cupboard, Make My Vape) carries the full 190+ flavour range. Known for strong, clean flavour profiles and their legendary Vanilla Custard V1 and V2, which appear in more recipes than any other single concentrate in the DIY world.

Standout flavours: Sweet Strawberry, Vanilla Custard V2, Super Sweet (the #1 go-to sweetener), Juicy Lemon, Sweet Mango, Caramel V2.

UK stockists: Vapable (largest official UK importer), Vapour Depot, Prime Vapes, Alchemists Cupboard.

2. FlavourArt (FA)

Country: Italy · Typical UK price: £1.69–£4.50 per 10ml · Recommended mix %: 2–8% (highly potent)

FlavourArt takes flavour creation as seriously as any house in the industry — their concentrates are used in many premium UK and European commercial e-liquid brands. Higher potency than most US brands, so recipes use smaller percentages. FA Lemon Sicily, Custard, and Black Cherry are benchmarks in the category.

Standout flavours: Black Cherry, Lemon Sicily, Custard, Meringue, Red Touch (strawberry), Dark Bean (coffee).

UK stockists: Vapable, Prime Vapes, Vapour Depot, Make My Vape.

3. Inawera (INW)

Country: Poland · Typical UK price: £2–£2.50 per 10ml · Recommended mix %: 1–3% (extremely potent)

Inawera concentrates are the strongest on the market — most recipes use 1–2% as a single-flavour base and 0.5–1% in complex mixes. Built their reputation on tobacco concentrates (Tobacco Reserve, RY4, 555 Gold) and the widely-used Inawera Biscuit, which appears in more custard, pie and bakery recipes than any other biscuit flavour in DIY. Their Shisha range is unmatched for authentic Middle Eastern fruit profiles.

Standout flavours: Biscuit, Tobacco Reserve, Shisha Strawberry, Cactus (the fruit-juicer), Wild Strawberry, Red Fruit Mint.

UK stockists: Vapour Depot, Vapable, Prime Vapes.

4. The Flavor Apprentice (TPA / TFA)

Country: USA · Typical UK price: £1.69–£3 per 10ml · Recommended mix %: 3–15% depending on flavour

TPA is the oldest and most-referenced brand in the DIY world — if a recipe online lists a concentrate without a brand prefix, it’s probably TPA by default. Huge range covering every flavour category, strong cream and bakery profiles, and the industry-standard Koolada (the cooling agent used for “ice” versions of fruit mixes).

Standout flavours: Koolada 10%, Vanilla Swirl, RY4 Double, Strawberry Ripe, Dragonfruit (a secret strawberry enhancer), Banana Cream, Brown Sugar.

UK stockists: Vapable, Vapour Depot, Alchemists Cupboard, Prime Vapes.

5. FlavorWest (FW)

Country: USA · Typical UK price: £1.49–£2.50 per 10ml · Recommended mix %: 5–15%

FlavorWest has one of the largest catalogues in the DIY industry and is consistently one of the cheapest. Flavour quality is variable flavour to flavour — their menthols and tobacco range are excellent, their custards are decent, their fruit profiles sit in the middle of the pack. Good for bulk DIY mixers who want range at low cost.

Standout flavours: Extreme Ice (the go-to menthol), Vanilla Tobacco, Pineapple, Vanilla Custard, Sour (adds tartness to fruit mixes).

UK stockists: Vapable, Vapour Depot, Prime Vapes.

6. Molin Berry (MB)

Country: Poland · Typical UK price: £1.70–£3 per 10ml · Recommended mix %: 3–8%

Polish house making a name for themselves with clean, vivid fruit profiles. Mixers use Molin Berry when Capella or TPA versions of a flavour don’t nail the character — their Creamy Watermelon, Bilberry and Wild Plum are notably better than the US alternatives.

Standout flavours: Creamy Watermelon, Bilberry, Wild Plum, Cheesecake, Sweet Toast.

UK stockists: Vapable, Vapour Depot.

7. Solubarome

Country: France · Typical UK price: £2–£4 per 10ml · Recommended mix %: 3–8%

Choosing Your First DIY Brands

Avoid over-buying in your first month. Ten well-chosen concentrates will give you access to hundreds of recipes. Each 10ml bottle lasts months at typical mix percentages.
