Luxury specialty ingredients are not year-round products. The finest truffles have a six-week peak. Some caviar lots are available in limited quantities that sell through quickly. Foie gras quality varies meaningfully by season. Building a menu program that makes the most of these peaks — and maintains quality between them — requires a deliberate seasonal calendar, not a static menu with luxury line items that don't change.

The Seasonal Framework for Key Ingredients

The basic seasonal availability calendar for TBGC's core categories:

• White Truffle (Tuber Magnatum): Mid-October through late December. Peak in mid-October to late November. The defining luxury season — drive special menu features and prix fixe experiences around this window.
• Black Périgord Truffle: December through March, peak January–February. The working-season truffle — integrate into sauces, compounds, and composed dishes for the winter menu.
• Black Summer Truffle (Tuber Aestivum): May through August. Lighter, nuttier character. Allows truffle presence on summer menus at significantly lower cost. Excellent on pasta, with eggs, and over simply prepared fish.
• Caviar: Year-round availability from farmed species. Review the full seasonal calendar for allocation timing and premium lot releases.
• A5 Wagyu: Year-round from Japanese export partners, with allocation tightness in September–October (fiscal year transitions in Japan).
• Foie Gras: Available year-round, best quality September–March when ducks carry more fat going into colder months.

Building the Annual Menu Calendar

Structure your luxury menu around four distinct seasonal moments:

• Fall Feature (October–December): White truffle season. This is your highest-impact luxury moment. Dedicated menu features, prix fixe option, table-side truffle shaving. The season is short — make it count.
• Winter Depth (January–March): Black truffle at peak, foie gras at best quality. Richer, more composed preparations. Truffle sauces, torchon courses, classical preparations that work with winter menus.
• Spring Transition (April–May): The inter-season — summer truffle begins in May. Bridge the gap with caviar features, wagyu presentations, and spring-forward compositions.
• Summer Lightness (June–September): Summer truffle, caviar, light wagyu preparations. Fresher flavor profiles, heat-friendly cooking methods that complement rather than fight the season.

Communicating Seasonality to Guests

The seasonal nature of premium ingredients is a selling point, not a limitation. Guests who understand they are eating white truffle during its six-week annual window will value the experience more than if they believe truffles are always available. Make seasonality explicit in your menu language:

• Use date-bound language: "White Truffle Season, October–December" rather than just "White Truffle"
• Brief server scripts explaining why this is the moment for this ingredient
• Email or social media announcements at the start of each season to create anticipation with your regular guests
• Waitlist or reservation incentives around peak season openings

Planning with Your Supplier

The practical complement to seasonal menu planning is advance communication with your supplier. Establishing your white truffle allocation at the start of October — before demand peaks — ensures supply when you need it most. The same applies to caviar standing orders and A5 weekly allocation windows.
