Home / Sour RDA Flavour in Bristol: the review shortlist

What the label on Sour is allowed to say

A sour RDA from the reviewed options in Bristol costs about £3.13 per 10 ml once delivery is counted. That number decides whether the habit survives the first month, not the sticker price.

Sour RDA reviews tend to be written after one tank. We run 15 units and 8 days per unit, because that is where the honest answer changes.

If you only read one line: the RDA you buy decides how long sour tastes right, and the coil inside it decides how long that is.

What a sour RDA really costs in Bristol

There is no single best way to buy Flavour in Bristol. There is only the batch that arrived, the coil that came with it, and whether the shop tracks the production run.

How we tested sour in a RDA

1. Pick the RDA that fits the device already on your desk, not the one on the headline page.
2. Choose strength against the ceiling in the UK, which is 20 mg/mL for retail here.
3. Order before 14:00 so the parcel leaves the same day and lands inside 2–4 business days.

• Batch code and production date, so a sour bottle turned in 8 weeks ago is not sold as new.
• Clear PG/VG ratio on the label, which predicts throat hit more accurately than strength.
• The listed nicotine ceiling, which is 20 mg/mL in the UK, not a suggestion.
• Stock depth: 15 lines held, so the shortlist does not turn into a special order.

Where sour goes wrong

• Ignoring the batch date on a RDA and discovering the listed price was for old stock.
• Treating the advertised £31 entry kit as the real cost when refills run £3.13 per 10 ml.
• Mixing sour with a coil rated for a different wattage, which dulls the flavour and drains liquid faster.

The rules that apply here

UK rules cap e-liquids at 10 ml and 20 mg/ml, with batch codes on every bottle.
