Argentine Sirloin Steak | Rioplatense Blue Box | Corn Feed 250 days

Description

Rioplatense Blue Box sirolin represents the essence of Argentinian style. Beef with character, natural juiciness, and the refined depth typical of South American flavour.

Angus cattle are raised on the green pampas of the La Plata River basin and finished on a corn-fed programme lasting 250 days. This approach creates an ideal balance between muscle structure and marbling.

The result is beautifully marbled beef with a deep, buttery profile and a silky texture that reflects passion, tradition, and precise modern craftsmanship.

Origin and Rioplatense philosophy:

The Rioplatense Blue Box programme showcases Argentinian expertise in beef production. Cattle are raised in the La Plata region across Buenos Aires and Santa Fe provinces, where open pastures and a mild climate provide optimal conditions for free-range Angus farming.

In the final stage, cattle transition to a corn-fed diet with 250 days of grain feeding based on high-energy maize.

This system delivers even marbling, finer muscle fibre structure, fuller flavour, natural juiciness, and consistent quality comparable to leading programmes from the USA and Australia.

The beef is wet-aged to preserve freshness, clarity of flavour, and the distinctive aromatic profile of premium Argentinian beef.

Flavour and characteristics:

• flavour bold and buttery with nutty notes and subtle grain-driven umami
• texture tender yet structured, the hallmark of South American beef
• marbling high, achieved through 250 days of corn feeding
• aroma gently caramelised after cooking, deep and refined
• best suited for grilling cast-iron pan or sous-vide
• seasoning salt pepper and a touch of olive oil

Argentinian style values simplicity, precision, and fire. Rioplatense Blue Box striploin is best enjoyed in its purest form.

What does Corn Fed 250 Days mean?
It refers to a finishing programme where cattle are fed a maize-based diet for a minimum of 250 days, resulting in higher marbling, improved tenderness, and fuller flavour.

How does Rioplatense Blue Box differ from standard Argentinian beef?
It is a premium export line with genetic selection and strict quality control over marbling and flavour, recognised by chefs worldwide.

What is the best way to cook Argentinian striploin?
On a cast-iron pan or grill, ideally cooked to medium-rare at 54 to 56 °C. This steak does not require sauces or marinades, as its flavour stands on its own.

Can the beef be frozen?
Yes. It is best frozen in its original vacuum packaging. Once defrosted, consume within 24 hours.
