Dry yeast is much more durable than liquid yeast. It has a longer shelf life (some up to 3 years) and doesn’t require refrigeration. Dry yeast ships easier without the need for ice packs, reducing the risk of decreased viability due to travel. An 11-gram packet of dry yeast is packaged with nutrients and contains double the cell count as a typical pack of liquid yeast. This makes it a much more affordable option, especially for higher gravity batches.
