Mangrove Jack’s M47 Belgian Abbey Yeast – 10g Sachet
This yeast is 40% off because it’s within at least one month of its best by date. We never ship expired yeast, but it may arrive near or just past that date. In our own lab tests, we've seen up to 85% viability beyond the best by date—much better than most calculators predict. It's a smart way to save without compromising your brew.
