Monster

Monster Energy at Local Supplies covers the current UK case selection – multipacks of 12 and 24 cans across the standard Monster Original range, the coffee-based Java line, the lower-calorie Ultra flavours, and the newer Voodoo Grape flavour. If you're buying a single can for the fridge, the supermarket's fine; the case format on this page is for people going through 6+ cans a week and wanting a better cost-per-can than the corner shop can offer.

Prices run from £30.99 for a 12-pack up to £69.99 for the biggest 24-pack. Same-day dispatch on weekday orders before 4pm, free UK delivery over £35 (which most cases hit on their own).

The Monster Energy Line-Up, Explained

Monster's UK range has grown a lot in the last few years. Rough guide to what's what, so you know which flavours belong to which sub-line before you pick a case:

Monster Original (Green)

The classic. High caffeine, high sugar, aggressive energy drink flavour that basically defined the modern energy drink category. Cans still say the same thing they did when it launched.

Monster Ultra

Zero-sugar, lower-calorie versions with fruit-forward flavours – Ultra Rosa, Ultra Sunrise, Ultra Wild Passion, Ultra Punk Punch, Ultra Vice Guava. Same caffeine hit as Original, none of the sugar. This is where most repeat Monster drinkers land if they don't want the sugar every day.

Monster Java

Coffee-based energy drinks – think ready-to-drink iced latte with the Monster caffeine kick added on top. Flavours include Loca Moca, Salted Caramel, Java Irish Cream and Mean Bean. Popular as a morning drink or for people who prefer coffee flavour to the fruit/synthetic profiles of Original and Ultra.

Monster Voodoo, Punch & Limited Editions

The rotating flavour range – Voodoo Grape, Hawaiian Punch, Strawberry Shot, Electric Blue. Sits between Original and Ultra in style. These come and go depending on stock and season.

Which Monster Line Suits What?

Quick sanity check before you pick a case:

  • Long shift, hard workout, hangover – go Monster Original or a strong Ultra (Ultra Wild Passion, Ultra Punk Punch). Standard 160mg caffeine per 473ml can, hits fast.
  • Daily drink, watching sugar – Monster Ultra range. Zero sugar, same caffeine hit. Ultra Vice Guava and Ultra Wild Passion are the most popular sugar-free picks.
  • Morning drink or coffee replacement – Monster Java. Coffee-forward, dairy notes, closer to a canned iced latte with extra caffeine than a traditional energy drink. Salted Caramel and Loca Moca are the sweeter picks; Mean Bean is closer to straight coffee.
  • Something different / gifting a mixed case – the 24-can 473ml mixed pack, or the Voodoo Grape case if you want a single stand-out flavour.

The 444ml vs 473ml Can Size Question

Both sizes are on this page and they're not the same product. Quick breakdown so you don't pick the wrong case:

  • 473ml (16oz) – the standard US-format Monster can, now common in the UK. The Original range, most Ultra flavours, Voodoo Grape and Hawaiian Punch all come in this size.
  • 444ml (15oz) – slightly smaller can, currently used for the Java coffee range and some newer Ultra flavours in the UK market.

Practically it's about a 30ml difference – roughly two big sips. Same caffeine per can in most cases, so per-can pricing matters more than can size when comparing cases.

Delivery & Ordering

Cases of drinks are heavier than most orders, so delivery matters. Weekday orders before 4pm ship same day; next working day delivery is available UK-wide. Free delivery over £35 – every case on this page qualifies on its own. Cases are packed to avoid crushed cans in transit; if a can arrives split or damaged, get in touch and we'll sort a replacement.

Monster Energy – Common Questions

How much caffeine is in a can of Monster? ×

A standard 473ml (16oz) Monster Energy can has around 160mg of caffeine – roughly equivalent to two standard espressos or one and a half instant coffees. The Ultra range has the same 160mg. The Java coffee range typically sits around 150–160mg per can. For context, Red Bull 250ml sits at 80mg, so a full Monster is about twice the caffeine hit.

What's the difference between Monster Original, Ultra and Java? +

Original is the classic green-can version – full sugar, aggressive energy drink flavour. Ultra is the zero-sugar range with fruit-forward flavours (Vice Guava, Wild Passion, Punk Punch, Rosa). Java is the coffee-based line – more like a canned iced latte with the caffeine hit added, in flavours like Loca Moca and Salted Caramel. All three use the same "Monster Energy Blend" and hit roughly the same caffeine level.

Is there an age restriction on buying Monster Energy in the UK? +

Legally, no – there's no age restriction on energy drinks in the UK. However, most UK supermarkets and many online retailers voluntarily restrict sales of high-caffeine energy drinks to 16+, following NHS and government guidance about caffeine consumption in under-16s. Individual retailers set their own policy.

How long does the Monster caffeine hit last? +

Caffeine has a half-life of roughly 5 hours in most adults, so a 473ml Monster (160mg) will still be affecting you 5–6 hours after you finish it. That's why energy drinks are usually a bad idea in the evening – the caffeine is still in your system when you're trying to sleep. Peak effect hits around 30–60 minutes after drinking.

Are Monster energy drinks vegan? +

Most of the Monster Energy Original and Ultra range is vegan-suitable – check the ingredients on the individual can, but the standard formulations don't contain animal-derived ingredients. The Java coffee range does contain dairy (milk), so those flavours are not vegan. If in doubt, the ingredient list on the can is definitive.

Are Monster cases the cheapest way to buy energy drinks? +

Per-can pricing on cases works out considerably cheaper than buying individual cans at a corner shop or petrol station, where Monster typically retails at £1.75–£2.50 per can. A 24-pack at £69.99 works out at £2.92 per can – not always cheaper than a supermarket single-can price, but you save the trip and have stock at home. Compare against a supermarket 4-pack price if you're deciding which format to buy.

How should I store Monster cans? +

Room temperature is fine – cans don't need to be refrigerated for storage, just cold when you drink them. Keep them out of direct sunlight and away from anywhere that'll get above 40°C (like a car boot in summer) as heat can affect flavour and, over time, the can pressure. Best-before dates are typically 12–18 months from manufacture.
