Cold pressed juice has become a high-margin menu category for cafes seeking to attract health-conscious customers willing to pay premium prices. Unlike centrifugal juicing, cold pressing uses hydraulic pressure to extract juice without generating the heat and oxidation that rapid blade spinning causes. The result is a juice with brighter color, smoother texture, and — proponents claim — better nutrient retention. However, from a food safety perspective, cold pressed juice is a high-risk product. It is unpasteurized, made from raw produce, and consumed without any kill step for pathogens. Multiple foodborne illness outbreaks have been linked to unpasteurized juice, making rigorous food safety controls essential rather than optional.
Unpasteurized juice carries inherent microbiological risks that pasteurized juice does not. Pathogens including E. coli O157:H7, Salmonella, Cryptosporidium, and Listeria monocytogenes have all been associated with unpasteurized juice outbreaks. These organisms can be present on the exterior of raw produce and are introduced into the juice during pressing.
Many jurisdictions have specific regulations governing the production and sale of unpasteurized juice. In the United States, the FDA requires a HACCP plan for juice production and mandates a warning label on unpasteurized juice sold at retail. In the European Union, food business operators must follow general food hygiene regulations (Regulation EC 852/2004) and may face additional national requirements. In the United Kingdom, the Food Standards Agency requires hazard analysis for juice production. Research and comply with the regulations specific to your jurisdiction before adding cold pressed juice to your menu.
The regulatory distinction between juice served directly to a consumer at a cafe counter and juice pre-bottled for later sale is important. Some jurisdictions exempt juice made and served immediately at a retail establishment from the full HACCP requirements applied to wholesale juice producers. However, if you bottle juice for grab-and-go sale, you may fall under packaged food regulations that require labeling, nutritional information, and production controls. Clarify your regulatory classification before investing in equipment.
The safety of cold pressed juice begins with the quality of the raw produce. Source from reputable suppliers who follow Good Agricultural Practices (GAP). Request documentation of their food safety protocols — a supplier who cannot provide this information may not have adequate controls in place.
Inspect every produce delivery upon arrival. Reject items showing signs of decay, mold, pest damage, soil contamination, or off-odors. Pay special attention to leafy greens (spinach, kale, wheatgrass) and sprouts, which have been implicated in multiple juice-linked outbreaks. If you include sprouts in any juice recipe, understand that sprouts are classified as a high-risk ready-to-eat food by most food safety authorities.
Store produce at the appropriate temperature immediately upon receipt. Leafy greens, celery, cucumbers, and herbs require refrigeration at 4-5 degrees Celsius. Citrus, apples, and root vegetables (carrots, beets, ginger) can be stored at slightly higher temperatures but still benefit from refrigeration to extend freshness and slow microbial growth.
Separate produce from raw animal products in storage. While a juice-focused cafe may not handle raw meat, if your menu includes sandwiches, eggs, or dairy, maintain clear separation in the refrigerator. Store produce above animal products to prevent drip contamination.
Wash all produce thoroughly under running potable water before pressing. Use a designated produce wash sink — never wash produce in a handwashing sink or a dish sink. Scrub firm-skinned produce (apples, carrots, ginger, beets) with a clean produce brush to remove soil, wax, and surface contamination.
For leafy greens, submerge in clean cold water, agitate to loosen debris, lift out (do not pour through a colander, which allows sediment to redeposit on the greens), and repeat with fresh water. Some juice producers add a food-grade produce wash or vinegar solution to the rinse water — this can reduce surface microbial load but does not eliminate pathogens and should not be relied upon as a sole safety measure.
Remove damaged, bruised, or decayed portions of produce before pressing. Damaged tissue supports more rapid microbial growth and can introduce decay organisms into the juice that accelerate spoilage. Trim generously — a small bruise on an apple can harbor bacteria beneath the surface that extends beyond the visible damage.
Cut produce on sanitized cutting boards using clean knives. If pressing high-allergen ingredients (such as tree nuts for nut milk blended with juice), use dedicated cutting equipment that is not shared with allergen-free preparations.

Disassemble the press to the extent recommended by the manufacturer and clean every component that contacts juice. Biofilm (a slimy layer of bacteria) can form in crevices, seams, and hard-to-reach areas of the press — visual cleanliness does not mean microbiological cleanliness.
Press juice in a temperature-controlled environment. The pressing area should be cool (below 21 degrees Celsius if possible) to minimize the time juice spends at temperatures that support bacterial growth. Process juice efficiently — do not leave pressed juice sitting in collection containers at room temperature while preparing the next batch.
Bottle juice immediately after pressing into clean, sanitized containers. Glass bottles or food-grade plastic bottles with tamper-evident caps are standard. Fill bottles completely to minimize headspace (the air above the juice), which reduces oxidation and slows aerobic bacterial growth.
Label every bottle with: the juice name and ingredients, the date and time of pressing, the use-by date, the storage instruction ("Keep Refrigerated"), and an allergen declaration if applicable. If your jurisdiction requires an unpasteurized juice warning, include it prominently on the label.
Refrigerate bottled juice immediately at 4-5 degrees Celsius or below. The shelf life of unpasteurized cold pressed juice is typically 3-5 days under proper refrigeration. Some producers use high-pressure processing (HPP) to extend shelf life to 30-45 days, but HPP requires specialized equipment that is beyond most cafe budgets. Without HPP, strict refrigeration and conservative shelf life limits are your primary safety controls.
Cold press equipment requires thorough cleaning after every production run. Juice residue left on pressing surfaces, in crevices, or in tubing becomes a breeding ground for bacteria and mold within hours.
Disassemble the press according to the manufacturer's instructions. Remove all screens, filters, pressing cloths, and collection trays. Rinse all components with warm water to remove visible juice residue. Wash with a food-grade detergent, scrubbing all surfaces including seams, threads, and screen mesh. Rinse thoroughly with clean water to remove all detergent. Sanitize using an approved food contact sanitizer at the manufacturer's recommended concentration. Allow components to air dry completely before reassembly — trapped moisture supports bacterial growth.
Pressing cloths (if used) should be washed in hot water with detergent after each use, sanitized, and dried completely. Replace pressing cloths regularly — even with proper cleaning, cloth fibers trap organic material that becomes increasingly difficult to remove over time.
Clean and sanitize the bottling area, funnels, measuring containers, and any other equipment that contacts juice during the bottling process. Include the exterior of the press in your cleaning routine — splashed juice on the outside of the equipment attracts fruit flies and creates a hygiene issue even if it does not directly contact the product.
Cold pressed juice production is one of the highest-risk food preparation activities a cafe can undertake. Staff must understand the microbiology of raw produce, the importance of temperature control, and the specific hygiene protocols that separate safe juice from a potential outbreak source.

No. Cold pressing is a physical extraction process that uses hydraulic pressure to squeeze juice from produce. It does not generate the heat needed to kill pathogenic bacteria. The temperatures involved in cold pressing are ambient or slightly elevated from friction — nowhere near the temperatures required for thermal pasteurization (typically 72 degrees Celsius for 15 seconds or equivalent). Cold pressed juice retains whatever microbial load was present on the raw produce, which is why thorough produce washing, sanitary pressing conditions, and strict refrigeration are critical controls.
Under proper continuous refrigeration at 4-5 degrees Celsius, unpasteurized cold pressed juice should be consumed within 3-5 days of production. The exact shelf life depends on the specific produce used, the microbial load of the raw materials, the sanitary conditions during pressing and bottling, and the consistency of refrigeration. Citrus-heavy juices (lower pH) may last slightly longer than green vegetable juices (higher pH). Always err on the conservative side — if in doubt about the age or storage history of a juice, discard it.
Selling unpasteurized cold pressed juice beyond your immediate premises introduces significant food safety and regulatory challenges. You lose control of the cold chain once the product leaves your cafe. Most jurisdictions classify bottled unpasteurized juice sold at retail as a "packaged food" subject to labeling requirements, nutritional information, and potentially HACCP plan requirements. Shipping unpasteurized juice requires insulated packaging with cold packs and temperature monitoring — and you bear liability if the cold chain is broken during transit. Many cafe-scale juice producers who want a delivery channel invest in HPP (high-pressure processing) to extend shelf life and reduce the regulatory burden.
