Triple Double Yeast | Imperial Yeast B48

Craft Bold Belgian Ales with Balanced Esters

Imperial Yeast B48 Triple Double is a high-gravity Belgian strain designed for brewing traditional Trappist-style ales. With its moderate ester production and minimal phenolic characteristics, this yeast delivers complex yet balanced flavors. Triple Double is highly alcohol-tolerant, making it ideal for fermenting robust Belgian ales such as Tripels, Dubbels, and Golden Strong Ales. This true top-cropping yeast forms a thick krausen during fermentation, a hallmark of classic Belgian fermentations.

Our Commitment to Yeast Health

At SoCal Brewing Supply, we take yeast storage and viability very seriously. We ensure yeast is always stored under optimal conditions, with 24-hour monitoring of refrigerator temperatures to prevent spikes that could negatively impact yeast health.

For liquid yeast orders, we recommend shipping with an ice pack and insulated envelope to ensure your yeast arrives in top condition. It’s normal for ice packs to melt during transit; their purpose is to protect the yeast from extreme temperatures caused by external weather conditions.
