01 — The Opportunity

The Opportunity

It started with a personal observation: my social circle was ordering sparkling water at bars and apologizing for it. I started asking why. The data confirmed what I was seeing wasn't anecdotal.

The European picture is unambiguous: the ESPAD study — the most authoritative longitudinal survey on youth drinking across 35+ European countries, running since 1995 — shows lifetime alcohol use among European adolescents dropped from 88% in 1995 to 74% in 2024. Recent alcohol use fell from 55% to 43% over the same period. In France, the proportion of 17-year-olds who have never consumed alcohol multiplied from less than 5% in 2002 to nearly 20% in 2022 (French Observatory for Drugs and Addictive Behaviors, 2023). In Britain, more than a quarter of 16–25 year-olds now describe themselves as teetotallers, compared with just 15% of those over 55.

But the most recent data adds nuance: IWSR's 2025 survey of 26,000+ European consumers shows Gen Z alcohol abstinence dropped by up to 10 percentage points in Italy and 9 in the UK year-over-year. Gen Z isn't simply abstaining — they're choosing deliberately, occasion by occasion. NielsenIQ confirms this: 31% of European Gen Z say they're drinking less than before, but they're drinking less alcohol, not drinking less overall. That's the bigger opportunity: they want intentional drinks worth choosing, not substitutes.

The market reflects this: the mocktail market is growing at 10.5% CAGR through 2029 (Technavio). Dry January participation grew 36% year-over-year in 2025, and non-alcoholic beer purchases rose 22% in 2024 (NCSolutions).

The product gap was clear: wellness-focused people had nowhere designed for them. Cocktail blogs assumed alcohol. Wellness apps ignored taste. No platform combined ingredient science with a discovery experience worth the occasion. That was the brief I wrote for myself.

02 — User Persona

Who I Built This For

One persona, drawn from a pattern I kept seeing: a woman who's choosing, deliberately what to drink, but nothing out there is designed for her

Cécile

Primary persona
Age 24 Occupation Digital Marketing Coordinator Location Paris, France Status Sober curious since 2023
Background

Cécile grew up drinking socially but started questioning it at 22 when she noticed alcohol affecting her sleep, skin, and energy. She didn't make a dramatic declaration — she just started choosing not to drink more often than she chose to. The problem: every time she's at a restaurant, a party, or hosting at home, her options are either "still water" or something that tastes like diluted juice. Nothing feels curated for her.

Goals
  • Find drinks that taste complex and intentional
  • Understand what she's putting in her body and why it helps
  • Feel like she's not missing out socially
  • Build a personal repertoire of go-to recipes
Pain Points
  • Mocktail recipes online are buried in cocktail blogs or parenting sites
  • Most apps assume she drinks — no-alcohol sections feel like afterthoughts
  • Recipe apps don't explain the wellness benefits of ingredients
  • Nothing helps her build a consistent ritual, just one-off recipes
Behaviors & Brands She Loves
Headspace Aesop Spotify Wrapped Oura Ring

Premium, personalized, science-adjacent — the brands she pays for know her and can explain themselves.

03 — Competition

The Competitive Landscape

Direct — mocktail-specific apps

Sippy The Mocktail Mixologist

Recipe database + AI bartender. No wellness angle, generic UI, low user ratings.

MockTale

Venue discovery — find NA-friendly bars. Not for home use or recipe discovery.

Mocktail Recipes App Luz Ochoa

Basic recipe list, 1.0 App Store rating, zero personalization, no design language.

Indirect — where Cécile actually solves this today

Ready-to-drink NA brands Ghia, Kin Euphorics, JNPR, Djin

The zero-effort answer to the same craving: an intentional, beautifully branded drink with functional ingredients — no recipe required. They own the "consolation prize → status object" repositioning Sip & Glow is built on, but at €25+ a bottle, and they sell products, not knowledge or ritual.

TikTok & Instagram mocktail creators

Where Gen Z discovery actually happens: visual, aspirational, free. But it's a feed, not a repertoire — recipes vanish into saved folders, there's no personalization, and the wellness claims are vibes, not science.

AI assistants ChatGPT & co.

The fastest-growing default: "give me a mocktail recipe with what's in my fridge." Instant and personalized, but generic taste, zero curation, no ingredient trust, and no ritual built over time.

Yuka & ingredient-scanning apps

Owns the "know what you put in your body" trust in France. It validates ingredients but stops there: no recipes, no experience, no discovery. Sip & Glow picks up exactly where Yuka's job ends.

The experience benchmark (not a competitor)

Headspace, Oura, Aesop

The brands that set Cécile's expectations for design, personalization, and science-that-explains-itself. Sip & Glow doesn't compete with them — it has to feel like them to earn its place on her home screen.

04 — The Brief

Audience
Gen Z wellness enthusiasts: mobile-first, design-literate, health-conscious
Role
End-to-end PM ownership: opportunity sizing, user research synthesis, product brief, information architecture, 4 user flows, a 12-screen inventory with prioritised user stories, UX critique, and a working TypeScript prototype
Tools

Sip & Glow is a mocktail discovery app for a generation that drinks less and expects more from their drinks, and from the products they use.

After 3 years managing food delivery products at Smood, I wanted to build a digital product at the intersection of food, wellness, and intentional consumption. So I did, end to end, as a solo PM: writing the brief, mapping every user flow before a single screen existed, defining the information architecture and visual system, and shipping a working prototype. This page walks through the thinking, from opportunity to shipped product.

05 — Visual Direction

Visual direction

Sip & Glow moodboard — electric yellow and lavender palette, botanical and graphic references, keywords clean, elegant, calming

The moodboard set the tone before any screen existed: clean, elegant, calming, but at the same time electric. Citrus yellows against deep purples, organic botanical texture against bold graphic shapes. The tension is deliberate: wellness apps default to sage green and beige whispers; drinks culture is vibrant and social. Sip & Glow lives where the two meet.

Color decisions

Typography

Serif headings signal editorial quality, not utility. Clean sans-serif body copy and UI labels keep everything effortlessly readable. Confident maximalism: Heading sizes run deliberately large (32–40px on key screens).

Illustrations

Every recipe gets a custom botanical illustration in an editorial watercolour-and-ink style, and each illustration's palette matches the recipe's benefit category (green for energy, etc).

06 — The 4 User Goals

Personalisation from
the very beginning

At onboarding, users pick one wellness goal, and that choice seeds their entire feed. Each goal owns a benefit colour that follows the user throughout the app.

Coral

Skin Glow

Boost collagen, reduce inflammation. Recipes built around turmeric, citrus, and antioxidant-rich ingredients.

Lavender

Calm

Lower cortisol, sleep better. Adaptogens and botanicals for winding down.

Green

Energy

No crash, sustained focus. Matcha, ginger, and clean caffeine alternatives.

Amber

Immunity

Strengthen your body's defences. Ginger shots, vitamin-dense blends, and seasonal support recipes.

07 — User Flows

Four flows, mapped
before any screen design

Every screen in Sip & Glow traces back to one of 4 flows.

01

Login / Authentication

/splash → /auth → /onboard

Key decision: split new and returning users at the auth check. Returning users skip the goal quiz entirely and land on discovery; first-time users take it once, and it seeds their personalised homepage feed. The quiz is skippable, so no one is blocked from entering the product. The flow also maps the full password-reset sequence, including the email-mismatch retry loop.

02

Discovery

/home → /search → /recipe/:id

Key decision: two parallel paths to one destination. Carousel browsing is passive and mood-driven; search is intentional, surfacing predictive results from the third character typed. Filters and search stack rather than reset, and an empty state covers the no-match case. Both paths converge on recipe detail — the centre of the product's core loop.

03

Host mode

/recipe/:id → servings stepper

Key decision: deliberately simple. One control, 2 directions, a live quantity update, and two hard limits (minimum 1, maximum 30 servings). Host mode turns a personal wellness app into something you can use to throw a party, without adding a single new screen.

04

Retention

/recipe/:id → mark as tried → /profile

Key decision: real-time feedback, not batched. The flow opens in a neutral state — both Try and Tried visible — and branches on whichever the user taps first. The tried count updates the instant a recipe is marked, reinforcing the behaviour before the user leaves the screen.

08 — Wireframes

Structure before style

Low-fidelity wireframes locked the hierarchy of each core screen before any colour or illustration entered the picture.

Discovery screen wireframe: header with avatar, benefit filter chips, trending and community carousels, personalised For You list

Discovery

  • Browsing is primary, search secondary. Hierarchy set by layout
  • Benefit filter chips always visible, first chip active by default
  • Two horizontal carousels + one vertical list personalised by goal
  • Avatar in header taps to profile
Recipe detail wireframe: editorial illustration hero, to-try and tried CTA buttons, ingredients with servings stepper, method steps, cool sister tip

Recipe detail

  • Hero illustration big enough to feel editorial, not so big it buries content
  • 2-button CTA (To-try / Tried) — the core retention trigger, placed before the ingredients
  • Host mode servings stepper sits inline with the ingredients header
  • "Cool sister tip" uses a left-border accent to stand apart from body copy
Profile wireframe: avatar, stats row (tried / to-try / mastered), ingredient library, tried recipes list, on my radar list

Profile

  • Goal badge under the name reminds the user of their chosen intent
  • 3-stat row (tried / to-try / mastered) — a visible scoreboard for the retention loop
  • Tried recipes to keep track of what has been tried
  • On my radar recipes to keep track of the saved recipes to try in the future

09 — Key Product Decisions

Why I built it this way

Goal quiz at onboarding

Whydid I ask users their wellness goal at signup?
Because users need to find relevant recipes immediately.
Whydo they need relevance immediately?
Because without context, all recipes look equally useful, which will be more likely creating paralysis, not engagement.
Whydoes that matter for retention?
Because a generic feed increases friction and the user leaves before discovering value.
Whyis personalization the solution and not just better search?
Because Gen Z expects apps to know them from day one (Spotify, TikTok, Netflix, etc. set this expectation).
Whydoes this make the product meaningfully different?
Because no existing mocktail app personalizes at all. The goal quiz is the core retention mechanism.

Leading indicators

"On my radar" saves

An intent signal — recipes bookmarked before they're tried.

Ingredient library growth per user

An engagement-depth signal — the ritual building over time.

What I'd do differently

I'd run 3–5 user interviews before writing a single user story. The persona is grounded in market data and pattern recognition, but real users would have sharpened the goal categories, the onboarding copy, and the search entry point.

13 — Try it yourself

Experience the prototype

The best way to judge a product decision is to feel it. Pick a goal, browse the feed, scale a recipe for 10 guests.
