Yeast starters offer higher cell counts at the time the yeast is pitched, leading to faster, healthier fermentations and better tasting beer!
You may be wondering how to make a yeast starter.  Well, lucky for you this kit contains everything you need for making your own yeast starter right out of the box, including step-by-step instructions!
This is the most common size used to make yeast starters using liquid yeast, great for higher alcohol beer and cold fermented lagers.
In the lab world, these flasks are known as "Student Grade," meaning there may be some cosmetic flaws in the glass, and the volume measurements are approximate due to variations in the thickness of the glass walls of the flask. This makes it a great flask for making yeast starters--at a great price!
We do not recommend the use of an electric element with these flasks. If this cannot be avoided, we suggest using a larger pot as a hot water bath on the stove.

Finally getting proper attenuation from my brews.
For many years, I had bad luck at getting attenuation down into "single digits" (1.009 or lower). Mine were usually stuck at 1.014, 1.012, 1.018 for bigger beers, but never showing a healthy fermentation. Now after having done 4 batches using starters, every single one has had greater attenuation than I've ever had in the 10 years prior. Yeast cakes seem more solid and compressed, residual sugar is less. Pretty much everything is just better now.

Cons: More a nit-pick than a "con". The volume graduations on the flask are way off. Thankfully, the 2L flask actually has a volume considerably larger than 2L, which is nice. For instance, my flask at the 1600ml line is actually a full 2L. If you use a scale and weigh the water you can see how far off they really are. Maybe even calibrate with a paint marker and new lines. It's not a big deal, it's not like I'm using it for measuring. But, just be forewarned the volume lines are far enough off that you do not want to measure anything important in this. I boil starters 15 minutes and if I start with the flask at 2L and boil that long I get about 2L at the end after 20% boil off.

Great way to build yeast starters
Good quality flask and send to work well. Wish they offered an advance kit that included the foam stopper and a sitting magnet.

Realize with only comes with 8 oz of DME so you'll need more after making a couple starters.

Opening is small
I have a Kimax flask and the opening is much wider. That makes it teasy to reach in thee and stir up DME. Harder to do with this flask.

Making a starter is super easy. Should have done this along time ago. I recommend buying or making a stir plate too.
