Flat Rate Shipping only $7.99 only from Northern Brewer
A yeast starter is one of the easiest and most dramatic ways to improve the quality of your homebrewed beer. A single pack of yeast often does not contain enough cells to ferment a beer properly - especially higher-gravity beers and lagers. Use this yeast starter kit to grow your yeast cell count to the proper pitch rate. Achieve the ideal attenuation in your brews.

Product Details

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.

This kit works great with either our Maelstrom™ programmable stir plate.

Cheap glass NOT Pyrex
The flask supplied with this kit is of inferior quality. For the price, this should at least have a Pyrex or borosilicate glass flask. Do NOT recommend. No problems with thermal changes or cracking but not what I expected. Could easily buy much better quality equipment through other suppliers for much cheaper.

It’s an Erlenmeyer flask with a foam stopper and some DME. The flask came unbroken, the DME didn’t explode in the box and make a mess and the foam plug fits the top... so yea I guess it’s pretty cool.

Not Borosilicate/Pyrex - Very Breakable
The flask is made with very thin glass, very slight bump on the bottom to the countertop broke a section off and made a huge mess the first use. Recommend buying these separate els-where. Look for borosilicate or pyrex glass.

No Problems
I've had no problems with the flask with two starters. I boil in a pot to avoid a boil over and then pour in the flask and drop into an ice bath. It handles the temperature change like it should, no problems. I bought a stir plate separately. When aligned properly on the flat spot, the bar makes no noise. It would be nice if there was a marking at the 2 liter mark (highest marking is 1800 ML).

Right out of the oven.
This really changed my brew and fermentation time. I used my normal yeast by started two days before brew. The yeast smelled wonderful after incubation. It had the smell of sourdough coming out of the oven. Totally enhanced by nrew.

Great set, but a bit pricey
The starter kit was good to get going on making more yeasties. I had an issue with my first flask cracking when cooled the first time. NB rushed me a replacement flask with recommendations on bulk heating and cooling the flask to reduce thermal stress. No issues so far with this one. I'm giving 4 stars because the customer service is excellent, but I think the flask quality could be a bit better than the made in India offering (Pyrex would be great) and would keep them from needing to send replacements. Also 4 stars because after the fact I realized you can get a real Pyrex 2L and 1 lb DME for less than the kit at a popular Seattle based online retailer.

Works great... I think!
I was able to put one package of yeast in the starter, allow it to sit overnight, then use it for 2 batches of beer the next day. The yeast seemed to do it's job in both batches, but I'm sort of new to beer making so it's just a guess. At this rate the kit will pay for itself in 3-4 batches.

Yeast Starter Kit
This is the second flask I have purchased. I found out by mistake that it could not be heated on an electric stove. My mistake. The new flask worked perfectly.

if I brew a 1.080-1.103 og brew how much yeast starter would I need for a 5 gallon batch or is there a calculator I can use ive never made a yeast starter ?
james K on Aug 31, 2017
BEST ANSWER: I use 1 quart of starter for a 5 gallon batch
Is this a flat bottom flask that can be used with a stir plate?
A shopper on Apr 14, 2017
BEST ANSWER: Sure is! Will give you a better pitching rate than just swirling. Also you can overbuild a starter and keep the yeast going for your next batch!
does it matter what yeast you use for the starter kit?
My beer let comes with dry yeast can I use that?
A shopper on Jan 5, 2017
BEST ANSWER: Almost any liquid yeast will benefit from a starter. I would avoid a starter for yeast blends as the different components can reproduce at different rates. I've never done a starter for dry yeast as the packets are nice and stable and cheap. For dry yeast just rehydrate and pitch. Starters are great otherwise and can really step up your brew.
Where is the stir plate mentioned in this video?
A shopper on Nov 7, 2017
BEST ANSWER: That's one we no longer carry, that was the "Vortex" stir plate. It's been replaced by the far-superior Maelstrom Stir Plate. ( SKU 40332 )
The video shows the use of a funnel, what size funnel is recommended and do you sell them?
David C on Sep 26, 2015
BEST ANSWER: I would recommend a 4.5" Funnel

and we do have them available on our website: http://www.northernbrewer.com/shop/4-5-funnel.
Can I substitute something else for the foam stopper? Like Aluminum foil?
A shopper on Jan 11, 2018
BEST ANSWER: Yes, you can wrap aluminum over the top - I have done this pretty much every time I used it. Be careful as some yeasts can be vigorous and the slurry can push out the top - but this could happen with the stopper too.
I have never made a starter I need to know how much extract to water I need if og is around 1.080 or1.103?
james K on Aug 30, 2017
BEST ANSWER: The DME extract to water ratio is always the same, regardless of OG, and instructions are included in the kit. The only variable is how big of a starter you need for the OG at hand. With such a high gravity beer, you should use a 2 to 3 liter starter volume, which should be churning away by the time you pitch to ensure rapid and complete fermentation.
