Watch Maelstrom® surge through starter wort creating a vortex like no other. The transparent body shows the magnets whipping through rotation. Plus, the seamless surface makes for easy cleaning.

Easy to use with an intuitive interface, the Maelstrom® sets the new standard as the most powerful and versatile homebrewing stir plate ever created for the home brewer.

Features:

  • Stir Bar Removal Tool
  • Includes a 50mm stir bar

  • Translucent body lets you watch the magnets in rotation
  • Standard 12V Power Adapter
  • Large 8″ W & x 8 ½” L stirring platform

 

Why a Stir Plate? The constant motion of a stir plate integrates oxygen, puts yeast in constant contact with nutrients, relieves built up CO2 and generally helps yeast to grow more rapidly.  That also means smaller starters.

MoreBeer 2,000 mL Erlenmeyer Flask – on sale for $19.99 + Free Ship Eligible, Limited Availability

Erlenmeyer Flask - 2000 mL Y430

2,000 mL/2 Liter Borosilicate Flask from MoreBeer for making yeast starters.

More Info

From the product description, check product page for current description, price and availability:

These Erlenmeyer flasks help the best brewers to make large yeast starters to get their beer fermenting fast. Large populations of active yeast help ensure a healthy fermentation, free of off flavors.  One of our favorite things about the Erlenmeyer flasks is that you can boil your starters directly in them!

Our large 2000ml Erlenmyer Flask is the ideal vessel to make a large yeast starter for 5 gallon lagers and high gravity brews. Because it is made from borosilicate glass you can move it from a boil on your gas stove into a cold water bath for cooling, without the risk of cracking. (We do not recommend the use of an electric element. If this cannot be avoided, we recommend using a larger pot as a hot water bath on the stove.) This means you can do the whole process in one container, keeping it simple and helping to reduce the risk of contamination when transferring from one container to another.

Recommended Process for Use of Flask:
Double Boiler Method

It is important for your safety to heat water in the flask with a heat source that distributes heat evenly. Our manufacturer has confirmed that direct heat to the glass can break down its integrity and break if the heat source doesn’t distribute evenly.

Morebeer! recommends using the “double boiler method.”  This process involves using a boiling water bath on the outside of the flask to heat up the water inside the flask.  All you need is a kettle 3 gallons or larger.  This process is much safer and efficient. If the flask should break or boil over, your kettle will be there to collect the contents, thus keeping your stove clean and keeping you away from potential harm.

Features

  • Massive 2L (2000mL) Capacity
  • Made from Borosilicate Glass
  • Fantastic price for a flask of this size
  • Produced for MoreBeer!
  • 6.5″ base 2.5″ top 10.75″H

Why make a yeast starter? (from our FAQ)
We build starters for 3 main reasons. First, to ensure yeast health. By making a starter 1-3 days in advance, you ensure that your yeast is healthy and strong and ready to do its job. Second, to create more yeast. By making the starter you will increase the cell count of the yeast, giving you a better chance of keeping bacteria’s and wild yeasts from fermenting your wort. Third, if you are making high gravity beers. If you are making a high gravity beer (1.060+) you will need more yeast to start the ferment faster. High gravity beers will also finish more completely when you pitch ample quantities of yeast.

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)

Hands on Review: Propper Starter Canned Starter Wort

Propper Starter Canned Wort by Omega Labs

This review is by Homebrew Finds Contributor Brad Probert.  Brad is an engineer, expert homebrewer and experienced reviewer.  Grab a link to Brad’s website at the end of this review.

Propper Starter Canned Starter Wort

I never used to be a fan of starters. I willfully ignored stories people would tell about their starters because I didn’t want starters to matter. Extra work strung out to a few days before brew day was something I just couldn’t get excited about. But then I did some experiments splitting a batch and fermenting one with a starter and one without. I then saw firsthand how the starter saved a couple of challenging lager fermentations. I could no longer be a denier.

I set about trying to make the process as easy as possible with a flask, stir plate, and even a small electric coffee kettle to allow me to keep the process contained to my basement brewing area. It was manageable, but I still couldn’t overcome the dislike of having to buy DME (and running short when I needed it), and the whole cooling process after I boiled the wort starter. Then I stumbled upon the Propper Starter canned starter wort in my LHBS. Could this be my savior?


Compare Prices Propper Starter Canned Wort, Review Continues Below


Propper canned starter wort is made by Omega Yeast Labs. Omega yeast labs opened in mid-2013, which makes it a newer kid on the block of homebrewing yeast suppliers. Based in St. Louis and Chicago, you will mostly find their yeast in the Midwest and East Coast areas. A yeast producer making a yeast starter seems like a natural/logical fit.

The can of Propper Starter contains concentrated wort and yeast nutrient. It’s made to be diluted to the proper concentration. One 16 oz. can of concentrated wort poured into your flask, then you fill up the empty 16 oz. can with water again and you’ve got 1 Liter of 1.040 gravity starter wort.
