Why Cold-Pressed Juice Is Your Body's Best Friend This Summer

Cold-pressing uses no heat, which helps protect the vitamins, enzymes, and antioxidants that processing strips away. Here’s the science, and why summer is the season to make it a habit.

QUICK SUMMARY

Not all juice is equal — the difference is what happens to the nutrients before they reach your glass. Cold-pressing skips the heat that pasteurization and processing rely on, helping keep more of what makes fruits and vegetables worth drinking. Summer, when your body is working hardest, is the right time to make it daily.

Summer is officially here - longer days, more movement, more sun, and, if we’re honest, more of everything that quietly drains us.

The heat asks more of your body than most seasons do. You sweat more. You lose more electrolytes. Digestion can slow. And most of us reach for whatever’s cold and available, usually something sugary, artificially flavored, or built to sit on a shelf rather than to nourish.

“Cold-pressed juice isn’t a trend. It’s one of the most intentional things you can give your body — and summer is exactly the season to make it a ritual.”

THE SCIENCE

What makes cold-pressed juice different?

Most shelf-stable juices are pasteurized or HPP-processed (high-pressure processing). Both extend shelf life - but heat and prolonged processing can degrade the delicate enzymes, vitamins, and antioxidants that make produce worth drinking. Cold-pressing uses a hydraulic press with no added heat, which helps keep those compounds intact.

The evidence is real and worth stating carefully. In a peer-reviewed comparison of grape-juicing methods, the cold-pressed (slow masticating) juice retained more total polyphenols, flavonoids, and vitamin C than juice made with a high-speed centrifugal juicer. A 2021 review in the journal Foods similarly found that heat processing reduces the stability of many polyphenols. The size of the gap varies by fruit and method. This isn’t a magic multiplier, but the direction is consistent: less heat tends to mean better nutrient retention.

	Store-Bought	HPP-Processed	Netty’s Cold-Pressed
Heat exposure	High (pasteurized)	Pressure-based	None
Live enzymes	Largely degraded	Reduced	Better preserved
Vitamins & antioxidants	Heat-degraded	Partially retained	Better retained
Added sugars	Often added	Varies	Never
Preservatives	Common	Sometimes	Never

In a peer-reviewed comparison, cold-pressed grape juice retained more polyphenols, flavonoids, and vitamin C than centrifugal juice pressed from the same fruit.

At Netty’s, every juice is raw, hand-crafted in small batches, never pasteurized, and never HPP-processed. We ship frozen to help lock in nutrients from the moment it’s pressed to the moment you drink it. See the full lineup on our cold-pressed juice plans.

THE PAYOFF

5 reasons your body welcomes it this summer

01	Hydration that carries more than water Water is essential, but it doesn’t carry many nutrients. Cold-pressed juice delivers fluid alongside naturally occurring minerals like potassium and magnesium — some of the same electrolytes you lose sweating through a hot afternoon.
02	Steadier energy Whole-food juice provides B vitamins, iron, and natural plant sugars — a gentler lift than an energy drink, without the additives. Paired with a balanced meal, it’s a smart part of your morning.
03	Skin support from the inside Vitamin C, beta-carotene, lycopene, and flavonoids act as dietary antioxidants that may help your body manage the oxidative stress of more sun exposure. Sunscreen protects from the outside; a nutrient-rich diet supports you from within.
04	A gentler choice for digestion Because cold-pressed juice is already broken down and free of insoluble fiber, many people find it easy on the stomach — a light, nutrient-dense option on hot days when a heavy meal is the last thing you want.
05	Everyday nutrients for an active season Cold-pressed juice is rich in vitamin C, zinc, and a range of phytonutrients — the kind of everyday nutrition that supports an active summer, when you’re asking more of your body than usual.

DID YOU KNOW?

Phytonutrients give plants their color — and many carry protective properties for us, too. Lycopene (in red produce) is studied for heart health, citrulline (in watermelon) for circulation, and a range of plant compounds for their antioxidant activity. Because several are heat-sensitive, gentle extraction helps keep more of them intact.

THE RITUAL

Make it your summer ritual

The most common reason people don’t juice regularly isn’t motivation - it’s time and access. Buying produce, washing, cutting, pressing, and cleaning up adds up fast. That’s exactly why Netty’s delivers cold-pressed juice straight to your door, frozen and ready. No equipment, no prep — just pour and go.

Plan	Juices	Price	Best for
Sampler	3 juices	$39.95	Just getting started
Bronze	5 juices	$55.95	A weekly wellness boost
Silver	6 juices	$67.95	Committed to the ritual
Gold ★	9 juices	$94.95	All-in on summer

Your wellness starts with one sip.

No prep, no hassle — just pure, cold-pressed juice delivered to your door, frozen and ready.
