The Deluxe Yeast Starter Kit will have you making top shelf yeast starters right out of the box. Yeast starters offer higher cell counts at the time the yeast is pitched, leading to faster, healthier fermentations and better tasting beer! Any beer will benefit from a yeast starter, but they're especially recommended for high gravity beers and cold fermenting lagers.

This kit includes step-by-step instructions for making a 2L starter, as well as some fantastic upgrades that set it apart from our standard Y320 starter kit. Once you've prepared the starter, sanitize and drop in the stir bar, install the foam stopper, and place the flask on the magnetic stir plate. Turn the dial up until a shallow vortex forms.

Magnetic Stir Plate
A stir plate will greatly improve the quality of your yeast starter by providing continuous aeration. Yeast need oxygen to produce sterols and multiply. When all the available oxygen is used up the yeast will stop reproducing. Using a stir plate will ensure that your yeast have all the oxygen they could ever want and they'll be able to reproduce as much as possible.

Foam Stopper
Many yeast starter kits include a rubber stopper and airlock, but we believe a foam stopper is the clear choice. The foam stopper will allow air to flow freely into your flask while keeping pesky bugs and other contaminants out. Simply spray or dunk the stopper in sanitizer before installing it. If you're going to store the starter for a couple days after its finished, remove the foam stopper and cover the flask with sanitized aluminum foil.

FermCap S
FermCap S is commonly used during the boil or during fermentation to reduce foaming. This can be a helpful tool when preparing a yeast starter as well since you're essentially brewing and fermenting a mini batch of beer. Use one drop when boiling the malt extract to help prevent boil overs. An Erlenmeyer flask is a relatively small vessel and extremely active yeast are likely to produce enough krausen to reach the top of the flask and spill out onto your counter. One drop of FermCap will help prevent this from happening.

Flask Marker
This wax pencil is used for writing on glass surfaces and washes off easily. Great for labeling and writing notes on your yeast starter.

Kit Includes:

  • 2000 mL Erlenmeyer flask (student grade)
  • Magnetic Stir Plate (stir bar included)
  • Foam Stopper
  • 1/2 lb Dried Malt Extract
  • 1 oz Fermaid K yeast nutrient
  • 1 oz FermCap S foam control
  • Flask Marker wax pencil

In the lab world, these flasks are known as "Student Grade". A great flask for making yeast starters! (Student grade is not the highest grade flasks and will have minor defects)

Douglas Praetzel on Apr 14, 2021
What material is the flask made of? Is it borosilicate and can I boil in it directly? Thanks!
Anthony Allen on Jul 7, 2020
BEST ANSWER: This flask is not borosilicate but is still good to boil with a direct flame and to put into an ice-bath when it is hot. We do not recommend heating this flask directly with electric stoves. For safety and consistency you can do a double boiler method in a saucepan. As always when dealing with glass and/or boiling liquids be sure to be careful and stay safe.
Is the foam stopper reusable? Are they sold separately?
Robert Clark on Jun 5, 2020
BEST ANSWER: Absolutely. Soak in StarSan, squeeze it out, and you're good to go. I re-sterilize it when I use it and put it in the flask still damp (not dripping mind you) while the yeast starter is spinning.
Does this include the stir bar? Not shown in contents list.
Chet Stockton on Nov 24, 2019
BEST ANSWER: Hello Chet, great question. Yes it does!

first time using a starter
gave the yeast a good boost. only issue was could not apply direct heat to the flask (not borosilicate glass) but that is a cost issue, and a water bath worked fine.

Peace of mind
Love the starter kit. I can now have the peace of mind that I can get an instant fermentation start with no log time during which my brew can become infected. I am always sure that I have active yeast and get a good "bubble" in hours rather than days. Love it!

Much easier
Got tired of shaking bottle and that was my first batch. I put to much time in yeast sitting. Turned out worth it, but this will be great!
