Who this page is for
You're launching an alkaline water brand, building a private-label alkaline program for a regional retailer or club channel, scaling an existing brand into Mexico, or evaluating Mexican capacity to ship alkaline water under USMCA into the US. PET is the format. This page tells you whether BEV fits.
If you're looking specifically for regular spring water or sugar-free flavored water, the same line runs both — see Spring water bottling in Mexico.
Why alkaline water — and why now
Alkaline water has been the fastest-growing category in bottled water for the last seven years. The premium price band (typically 2–3x the price of regular spring water) makes the unit economics work even at lower volumes than mainstream water.
What buyers respond to:
- Higher pH as a perceived health and recovery benefit.
- Mineral profile — calcium, magnesium, bicarbonate — pitched as "smooth taste."
- Premium positioning that lets the brand sit on the same shelf as Smartwater, Essentia, or Liquid Death without the cost structure of a national brand.
From a co-packing standpoint, alkaline water is one of the cleanest categories to run: low microbial risk, simple QC, no flavoring, no carbonation. The complexity is in the pH targeting and mineral profile control — and that's what we built our line around.
Two paths to alkaline — naturally alkaline vs. electrolyzed
There are two ways to get alkaline water into a bottle. We can run either:
1. Naturally alkaline source water
Some underground formations produce water with naturally elevated pH — typically from contact with limestone or dolomite over long retention times. The mineral profile (calcium, magnesium, bicarbonate) is the source's, not added.
Pro: cleanest marketing claim ("naturally alkaline"), highest premium tier.
Con: less control over exact pH — you bottle what the source gives you.
2. Electrolysis-adjusted pH
The alternative: take regular spring or filtered water and run it through an electrolysis cell that separates alkaline from acidic fractions. The alkaline fraction (higher pH, higher OH⁻) is what gets bottled.
Pro: precise pH targeting (8.5, 9.0, 9.5 — pick a number).
Con: regulatory framing has to be careful — it's "alkaline water" but not "naturally alkaline."
We can run both. For most launching brands, electrolysis is the right call — predictable pH, consistent product, easier to scale. For premium / "naturally alkaline" positioning, we'll work with you on source-water selection and naturally alkaline source qualification.
A note on labeling — alkaline doesn't have an FDA standard of identity
Unlike "spring water" (which has a strict FDA definition under 21 CFR 165), alkaline water doesn't have a regulatory standard of identity. That's actually a feature — you have more flexibility in how you market and label.
What this means in practice:
- You can call it "alkaline water," "alkalized water," "ionized alkaline water," "9.5 pH water," or any reasonable variant — as long as the pH claim is accurate and substantiated.
- You can layer in mineral claims ("electrolyte enhanced," "magnesium-rich") if your formula supports them.
- You can position alongside premium water without claiming "spring water" — useful if your source isn't a true spring.
What you can't do: claim health benefits the FDA hasn't approved. The well-established benefits (hydration, electrolyte balance) are fine. Disease-treatment claims are not.
What we bottle on the same line
The PET line runs three categories — same equipment, separate runs:
- Alkaline water (this page).
- Spring water — see Spring water bottling in Mexico.
- Sugar-free flavored water — functional waters, electrolyte-fortified, vitamin-fortified, naturally sweetened.
What we don't bottle in PET: juice, dairy, sparkling water (PET cold-fill doesn't carbonate), HPP, hot-fill, aseptic. If your alkaline water is also carbonated, see our cans page — we can do alkaline-style mineralized sparkling in cans.
Six bottle sizes
| Size | Format | Typical alkaline use |
|---|---|---|
| 500 ml | 17 oz | Premium single-serve, gym / fitness positioning |
| 750 ml | 25 oz | Sport-cap fitness, tall-format premium |
| 950 ml | 32 oz | "Big bottle" hydration, post-workout |
| 1 L | 34 oz | On-the-go, cooler-door positioning |
| 1.5 L | 51 oz | Multi-serve, table format |
| 2 L | 68 oz | Family multi-serve, value-pack |
Decoration options: shrink sleeves (most common — full-body design), pressure-sensitive labels (premium positioning), or print-direct-on-bottle for the highest-end SKUs. For alkaline water specifically, blue/teal/silver color schemes lead the category visually — your designer will know.
Capacity and lead time
- PET line speed: 9,000 bottles/hour cold-fill on European-grade equipment.
- Annual capacity: 40 million liters/year total across all PET categories.
- Standard lead time: ~6 weeks from approved spec and materials to first pallets in your warehouse. Repeat runs after the first move faster — 3–4 weeks once formula and materials are in standing supply.
For a launching alkaline brand, 100,000 bottles is a single production run — your first pallets shipped about six weeks after we lock the spec. For an established brand on quarterly cadence, multi-million-bottle runs fit in the schedule.
MOQ — 100,000 bottles per SKU
Minimum order: 100,000 PET bottles per SKU. That's roughly one production run on the PET line.
For private-label alkaline programs at regional retailers, 100,000 bottles is a sensible launch quantity — alkaline turns slower than mainstream water, but the higher unit margin compensates. For brand-built programs, 100,000 is enough inventory for 4–8 weeks at moderate-velocity stores.
Quality and regulatory
SQF Edition 9 certified
Cert 25-7302, audited annually by Mérieux NutriSciences. Scope covers Cat. 16 — Beverage Processing, including water bottling.
Anton Paar QC for alkaline water
Same QC stack as spring water, with extra emphasis on pH and mineral content because that's what the product actually is:
On-site Anton Paar lab, every batch:
- pH verification (the headline number — has to match your label exactly).
- Alkalinity titration (separate from pH — measures buffering capacity, sometimes claimed on labels).
- Mineral profile (TDS, conductivity, calcium, magnesium, sodium, bicarbonate).
- Microbiological screening (heterotrophic plate count, total coliforms, E. coli).
- ORP (oxidation-reduction potential) — sometimes claimed on premium "ionized" alkaline brands.
- Bottle-integrity check on every shift.
In-line monitoring: continuous pH, conductivity, and temperature on the line. If pH drifts outside spec by even 0.1 units, the line stops and the operator investigates.
No batch ships without a COA.
Regulatory paperwork
COFEPRIS — sanitary registration and label review. Mexican alkaline labeling requires clear pH disclosure.
FDA — no standard-of-identity to comply with, but truth-in-labeling rules apply. We provide the source-water analysis and pH verification documentation US importers need.
EU — handled with the regulatory paperwork built into the engagement.
How we engage on alkaline water projects — four tiers
| Tier | What we cover | Best for alkaline projects |
|---|---|---|
| Full Project | Development → Design → Legal → Sourcing → Manufacture → Logistics | Founders launching a new alkaline brand, retailers building a house alkaline SKU |
| Full Tolling | Sourcing → Manufacture | Brands with brand identity, design, and target pH but no Mexico supply chain |
| Hybrid | Sourcing → Manufacture → Logistics | US alkaline brands nearshoring with cross-border distribution into the US |
| Soft Tolling | Manufacture only | Established alkaline CPG bringing own materials |
For new alkaline launches, Full Project is most common. For private-label programs (a regional retailer wants their own house alkaline SKU), it's also Full Project — design, source-water selection, materials sourcing, manufacture, and logistics all need to come together.
Why nearshore alkaline water bottling to Mexico
Same four reasons as spring water, with an alkaline-specific twist:
- Tier-1 PET equipment at Latin American operating cost. Our PET line is European-grade. Operating costs in Mexico make the unit economics on premium alkaline work even better.
- USMCA tariff treatment for finished water. Cross-border movement of finished bottled alkaline water from Mexico to the US is fast and predictable.
- Source-water options. Mexico has more accessible naturally alkaline mineral sources than US bottlers typically realize. We've built relationships with the qualified sources for clients who want naturally alkaline positioning.
- Same time zone, bilingual operations. US Central Time. Quote, contract, technical specs, COAs all available in English or Spanish.
Frequently asked questions
What pH can BEV target?
Anywhere from 7.5 to 9.5, with the sweet spot for the alkaline category at 8.5–9.0. Above 9.5, taste becomes a problem — the water gets soapy. Below 8.0, the alkaline claim feels weak. We'll guide you to the right number.
Can BEV provide a naturally alkaline source?
Yes — we've sourced from naturally alkaline strata for clients who want the strongest naturally alkaline marketing claim. Lead time on naturally alkaline source qualification can add 2–4 weeks to first-run timelines, depending on the source's availability and analytical readiness.
What's the difference between alkaline and ionized water?
Ionized is a marketing term for water that's been through electrolysis. The two are often used interchangeably in marketing, but technically: alkaline = high pH; ionized = electrolyzed; ionized alkaline = electrolyzed water with the alkaline fraction bottled. We can produce all three positioning angles.
Can BEV add electrolytes or minerals to the alkaline base?
Yes. Many premium alkaline brands fortify with magnesium, calcium, or proprietary mineral blends. We can run a mineral-fortified formula on the same line — adds about 1–2 weeks to first-run formula development.
What's the smallest first run for a new alkaline SKU?
100,000 PET bottles per SKU. Production-run economics of the PET line.
Can we use our own bottles, caps, or labels?
Yes — that's Soft Tolling. You ship your bottles, preforms, or label rolls; we run the line. For Full Project / Full Tolling / Hybrid, we source through our supplier network.
Do you ship internationally?
Yes — primarily to the US under USMCA. EU and other LATAM markets handled with regulatory paperwork built into the engagement. Bottled water is heavy and low-margin — most water programs target USMCA distribution.
Where is BEV's plant?
Tlazala #73, Col. San Miguel Tecpan, Jilotzingo, Estado de México 54571. Northwest of Mexico City, in the highland industrial corridor.
