Wyeast 3787 Belgian High Gravity

Brew authentic Belgian abbey ales with Wyeast 3787 Belgian High Gravity, a premium liquid yeast strain renowned for producing the complex balance of fruity esters, spicy phenolics, and dry finish that define classic Trappist-inspired beers. This versatile strain performs exceptionally well across a wide fermentation range while maintaining excellent attenuation, making it a favorite for both traditional Belgian recipes and creative specialty ales. Wyeast 3787 is ideal for brewing Belgian Dubbel, Belgian Tripel, Belgian Golden Strong Ale, Belgian Specialty Ale, and Bière de Garde.

Wyeast 3787 develops layered flavors of dark fruit, light spice, and subtle peppery phenolics while allowing malt complexity to remain prominent. Fermentation temperature can be adjusted to emphasize either fruit-forward esters or a more restrained Belgian profile, giving brewers flexibility to tailor the finished beer. As a true top-cropping strain, it produces vigorous fermentation and benefits from additional headspace during active fermentation.

This liquid ale yeast features medium flocculation, 74–78% attenuation, and an alcohol tolerance of 11–12% ABV or higher. It performs best between 64–78°F (18–25°C), providing dependable fermentation across a broad range of Belgian beer styles while delivering the high attenuation needed for strong ales with a dry, balanced finish.

For best results, keep the yeast refrigerated until use and pitch into well-oxygenated wort. Because this strain ferments vigorously, leave ample headspace or use a blow-off tube during primary fermentation. Healthy pitching rates, proper oxygenation, and temperature control will help maximize attenuation while producing the expressive Belgian esters and phenolics this strain is known for.

Trusted by homebrewers and commercial brewers alike, Wyeast 3787 Belgian High Gravity delivers the authentic fermentation profile expected in classic Trappist-inspired beers. Its combination of high attenuation, complex flavor development, and reliable performance makes it an outstanding choice for brewing rich, expressive Belgian ales with exceptional balance and drinkability.
