Egg Grading & Sizes Explained: What Food Businesses Need to Know | Suncoast Eggs Supplier Blog

If you've ever opened a wholesale egg delivery and noticed some size variation, or found a recipe producing inconsistent results despite using the "same" eggs, egg grading might be the missing piece of the puzzle. Here's a straightforward breakdown of how commercial eggs are graded and why it matters for food businesses on the Sunshine Coast.

What Does Egg Grading Actually Mean?

Egg grading refers to the quality assessment and size classification of eggs before they reach commercial buyers. In Australia, egg grading is governed by strict standards that cover shell cleanliness and integrity, internal quality (air cell size, yolk firmness and albumen clarity) and weight classification by size tier.

Australian Egg Size Classifications

Australian eggs are sold by weight per dozen. The commonly used size tiers are:

• Jumbo (700g+): The largest commercial grade, ideal for wholesale food service where egg volume and yolk size are priorities. This is the standard we supply at Suncoast Eggs.
• Extra Large (600–699g): Used widely in commercial kitchens. Great for scrambled, poached and fried egg dishes.
• Large (500–599g): Often found in retail packs. Less common in wholesale food service supply.
• Medium and Small: Rarely used in commercial applications unless specified by a recipe.

Why 700gm Wholesale Trays?

Suncoast Eggs Supplier focuses on 700gm wholesale trays because this is the sweet spot for commercial kitchens. Larger eggs mean more usable content per egg, better visual results in plated dishes and more consistent baking outcomes. If a recipe specifies 3 large eggs, using 3 jumbo eggs gives you slightly more volume, which often improves the final product.

Shell Grade vs Size Grade

It's worth understanding that shell grade (appearance and cleanliness) and weight grade are separate assessments. A Grade A egg has clean, intact shell with no cracks, a firm yolk, clear thick albumen and a small air cell. Commercial wholesale supply should always be Grade A. If you're receiving cracked or dirty eggs in your delivery, that's a quality control issue worth raising with your supplier.

Does Egg Grade Affect Cooking Outcomes?

Yes — particularly in precision baking. Cakes, custards, soufflés and hollandaise are sensitive to egg volume. Using consistent 700gm grade eggs means your pastry team isn't guessing. It removes a variable and keeps your recipes reliably repeatable from one production batch to the next.

Ordering the Right Grade for Your Kitchen

For most Sunshine Coast food businesses, 700gm wholesale egg trays are the right choice.
