Description

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 do I 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 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.

Good starter kit
This is my first yeast starter kit and I have been pleased with the quality of product that I received. I do recommend this product and also you need to find a good yeast calculator online that will give you specific measurements.

Satisfied
I follow the instructions as written except i boil the ingredients in a different pot then pore the boiling wort into the sanitized glass container to prevent boil over.

Get into yeast culture
I'm a first-time brewer who did a ot of research beforehand. I used this kit with a liquid yeast pack and WOW did it take off. I did not experience any boil over or foaming , and I did not use a stir plate. All is used was the kit, the packet, and filtered water. I had read that there would be little sign of yeast activity, but after 48 hours my starter was happily bubbling away. I brewed today and checked my fermentasaurus after a few hours and found it pressurized to the limit already. I thought I had a day to make my spunding valve, but it became a priority. This kit is your foray into understanding and manipulating yeast.

MUST HAVE PRODUCT - But Beware the Instructions
I pitched my first starter last night, and this afternoon I can already say I will never direct pitch yeast again! The last batch I brewed (direct pitch) had a lag time of over 24 hours. With the starter, I had a fully active fermentation in less than 12, and the bubbling from my blow off has never been more vigorous. I wish I had purchased a yeast starter kit much sooner, as I'm sure I could have been getting way better results when I was still extract brewing.

However, the instructions for making the starter could be better. The instructions and included DME are for making a 2L starter..... in a 2L flask. This is probably ok if you boil the starter wort in a pot and then transfer to the flask, but the instructions led me to believe I could do the boil in the flask directly on my gas range. Having tried it, I honestly can't imagine how you can bring 2L of starter wort to boil in a 2L flask and NOT have a boil over. Luckily I saw it coming and was able to safely move the flask to the sink just before it boiled over, narrowly avoiding what would have been an incredible mess. I was left with about 1600ml after the boil over, moved it back to the flame and was able to keep it boiling without any other issues. So maybe this kit should be sold with enough DME to make a 1600ml starter instead of 2L, or the instructions should encourage you to boil the starter wort separately. Personally, I wanted to boil inside the flask to be sure it was completely sterilized. Also be aware that although you're supposed to use the entire package of DME you are NOT supposed to use the entire packet of yeast nutrient. Whoops! When I realized what I'd done I called down to MoreBeer and the customer service rep assured me that the starter would come out fine, but I should probably put the starter in the fridge the night before brew day and decant it before pitching. Thank you MoreBeer for having great advice and knowledge that's only a phone call away!

After boiling for 15 minutes I topped the flask with foil and transferred to ice bath, trust in the borosilicate glass! Having the wort in the flask at this stage is great because you can easily pick it up (with oven mitt) and swirl the wort every few minutes to help with the heat exchange and cool the wort faster, all the while keeping it covered and protected from outside contaminates. Once it was cooled to room temp I pitched the yeast and put it on my stir plate. Definitely recommend investing in a magnetic stir plate. So easy to use, set it and forget it.

After 24 hours on the plate and 24 hours resting, I had a nice big yeast cake at the bottom of my flask. Put it in the fridge the night before brew day, decanted, and pitched. Hands down the best upgrade I've made to my brewing kit. Stop waiting and start making starters!

Yuge Difference!
I am still relatively new to homebrewing (about 6 batches), and just switched to liquid yeast for my last couple batches. I was noticing a lot of caramel flavor in the beers, likely from underutilized sugars. My gravities seemed to be right, but I felt that I must be underpitching my yeast. I got this kit along with the oxygenation kit, and the fermentation on my last batch was well beyond any of my prior beers.
In fairness, it was probably overpitched this time. I made a 1000ml starter, and was not sure if I had healthy yeast or not. I used an airlock, and while there was activity in the flask and bubbles when I swirled it, I never saw it bubble like it does on a carboy. After a couple days, I dumped off the fermented liquid and repitched in a new batch of wort. This time the starter went crazy. It's hard to say if the more active fermentation is more due to a fully oxygenated wort, or the increased cell count from the starter, but it's the first time that I have had an airlock filled with yeast. My batch yielded about 4-1/2 gallons in a 7 gallon Fermonster and the krausen filled all the headspace and then some. Hopefully overpitching won't ruin the batch, but I know I won't have to worry about underpitching again.
My only gripe is that I wish it had more volume markings. There is not a marker for 1000ml, and guessing where it should be given the conical shape of the flask is a crapshoot, so I'll have to do it myself.

Love the 2000ml Erlenmeyer Flask
I typically make 1200ml starters (10g/100ml) and this thing is perfect. I have used it dozens of times and went straight from my gas burner on my stove to the ice bath in my sink. Do not use on an electric element type burner.

Funny story and a warning to those who may have yet to experience this: I was attempting to sterilize my stir bar during the last 2 minutes of my boil inside my flask. Let's just say that is NOT a good idea!!! The moment I slid my stir bar into the flask down the side, it erupted into a cone of boiling wort all over my vent hood, stove and floor. It was hilarious since I managed not to get burnt. What a mess!!! You have been warned!

Improved my starters
Before theis kit I was using some random bottle for starters. More comfortable using this piece of glass wear.

Lagers
If you're making a lager for the first time you are likloey to under pitch. You will need this starter kit to make sure you are pitching enough. I highly recommend it.

Nice to have but consider a 5000 mL over a 2000 mL. Best Price on the Net !
I enjoy being able to add direct heat (gas stove) to my erlenmeyer and quickly cool in an ice water bath with no worries. Fastest way to get your yeast starter going. I only regret I did not get a 5000 mL size. MrMalty.com suggest I use a 3000 ml starter with my aged Wyeast smack pack. I need to at least buy a second 2000 mL sized erlenmeyer to brew beers over 1.060 OG with a 3 month old yeast packet. Might be better to have two 2000 mL flask if you want to cill the starter in a refrigerator to flocculate the yeast quicker or store your starter a couple extra days. The two 2000 mL size flasks will fit better in the refrigerator next to the milk jug.
