A Comprehensive Guide to Truffles: Varieties, Products, and Market Insights

Introduction

Truffles, the highly prized subterranean fungi, belong to the genus Tuber and are renowned for their unique aroma and flavor. They form symbiotic relationships with tree roots, primarily oaks and hazels, and are harvested using specially trained dogs or pigs. This article explores the diverse varieties of truffles, their culinary applications, market dynamics, and tips for storage and usage.

Truffle Varieties

1. White Truffle (Tuber magnatum)

Known as the "Alba truffle," this variety is predominantly found in Italy and Croatia. It has a pungent, garlicky aroma and commands the highest prices in the market, often exceeding €5,000 per kg during peak season.

2. Black Truffle (Tuber melanosporum)

Also called the "Perigord truffle," it thrives in France and Spain. With a robust, earthy flavor, it is a staple in gourmet cuisine. Prices range from €800 to €2,500 per kg, depending on quality and seasonality.

3. Summer Truffle (Tuber aestivum)

Milder in aroma, summer truffles are more affordable (€200–€600 per kg) and are harvested from May to August. They are often used in salads and light dishes.

4. Winter Truffle (Tuber brumale)

Similar to black truffles but less intense, winter truffles are harvested from November to February. They are a cost-effective alternative for chefs.

5. Burgundy Truffle (Tuber uncinatum)

Harvested in autumn, this variety has a nutty flavor and is popular in French cuisine. Prices average €300–€800 per kg.

6. Bianchetto Truffle (Tuber borchii)

Often confused with white truffles, bianchetto truffles are less aromatic and more affordable (€200–€500 per kg).
