Propagating a single pack of yeast using our yeast starter kit exponentially increases the number of cells you pitch. With a higher pitching rate, you will see a shorter lag phase, lower amounts fermentation-related off-flavors, and less incidence of bacterial contamination in your homebrewed beer.
Preparing a yeast starter is easy - you mix a very small batch of malt extract wort (without hops), briefly boil and chill it, then ferment it in a flask a day or two before brewing the main batch. The yeast cells from a single pack of yeast will reproduce in the starter, increasing in number from a few dozen billion cells to hundreds of billions.
The 2000 ml yeast starter kit is preferred for large starters for lagers, strong beers, and 10 gallon batches of homebrew. It features a heat-resistant borosilicate glass flask, which allows you to boil, cool, and ferment the starter wort in the same vessel. Also includes a foam stopper, one pound of DME, and complete instructions.
