We highly recommend making a yeast starter when using a Wyeast Activator or Propogator pack, even though a freshly swollen Activator will start 5 gallons of wort on its own. A starter will supply more yeast than an Activator pack can provide, assuring the fast start of fermentation, which minimizes the risk of bacterial infection and subsequent sour beer. Making a yeast starter can also revive an old Wyeast pack that has not swollen enough to use.
Our Yeast Starter Kit includes a 1000ml Erlenmeyer Flask, Foam Stopper, Anti-Foam, Safety Mit, and 1 pound of Dry Malt Extract as nutrient (enough for 12 400ml starters). Our Yeast Starter Kit is unique in that it includes food grade Anti-Foam and a bacteria filtering foam stopper, so you can boil the nutrient in the Erlenmeyer Flask on a stove without the nutrient foaming over, reducing the chance of infection. Because Anti-Foam is included, starters can be made to 400 or 800ml volumes in the included 1000ml flask.
A gas stove is recommended for the Erlenmeyer flask, as electric burners can cause the glass to crack.
Order a Stir Starter stir plate (see link below)to increase yeast growth and activity.
