What is the Scoville scale grade of an espellette pepper?

The Espellette pepper, known for its distinctive flavor and moderate heat, is rated between 4,000 and 5,000 Scoville Heat Units (SHU). This positioning on the Scoville scale makes it a versatile ingredient in various dishes, providing warmth without overwhelming a dish's overall flavor profile. The 4,000 SHU value correctly reflects the general assessment of Espellette peppers, as they are celebrated for adding a mild heat that pairs well with many foods, enhancing rather than dominating the dish’s taste.

The other options don't accurately represent the heat level of Espellette peppers according to established sources, as they place the heat either too low or too high in relation to the established range for this specific pepper variety.
