Juice N Power

The theme is plain Liquid plus a small JavaScript layer for the bits that genuinely need it, age verification, variant selection, and the cart drawer. Sections are metafield-driven so editorial content lives in Shopify rather than in code, and the product page is built around the variant model: each flavour and strength combination maps to a real variant rather than a synthetic option, so inventory, pricing, and analytics stay accurate end to end. Performance work focused on the LCP element on category and product templates: responsive image sources, inlined critical CSS, and deferring anything below the fold.

Vape e-commerce is mobile-heavy and variant-heavy. Most customers arrive on a phone, on a paid ad, looking for a specific flavour at a specific strength. A theme that can't get a customer from PDP to add-to-cart in one tap, or that buries the variant they actually want behind an option picker that ignores stock, costs orders.

Variant model that mirrors the catalogue

The vape category has unusually deep variant trees. A single product might exist in twelve flavours across three nicotine strengths and two bottle sizes, with combinations selectively in stock. The previous theme collapsed this into a single "select an option" dropdown that didn't reflect inventory and produced add-to-cart failures at checkout. The custom theme models each combination as a real Shopify variant and surfaces inventory state inline, so customers see what's actually available before they tap add.

Age verification that respects returning customers

UK retail rules require an age gate, but a gate that fires on every single visit costs conversions and trains customers to dismiss it without reading. The implementation here gates first-time visitors only, records the confirmation in a long-lived signed cookie, and falls back to a re-prompt only when the cookie expires or the visitor switches device. The cookie is set first-party so it survives the tracking restrictions that affect third-party storage.

Editorial sections in metafields

Every content surface that the marketing team needs to touch, the home hero, category headers, the brand storytelling band, the lifecycle promotion slots, is backed by a metafield. The theme is generic; the content lives in Shopify. That means a campaign refresh is a copy edit, not a developer ticket.
