Please note: It is highly recommended that a cold pack be purchased when ordering liquid yeast. High Gravity cannot guarantee the viability of liquid yeast if it fails to work unless it was purchased with a cold pack. You can add it to the order by checking the cold pack box near the bottom of the page before adding the yeast to the cart.
