MoreBeer Deal of the Day – 1,000 mL Erlenmeyer Flask – $10.99 + Free Ship Eligible, Limited Availability

Erlenmeyer Flask - 2000 mL Y430

1,000 mL/1 Liter Borosilicate Flask from MoreBeer for making yeast starters.

More Info

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

The best brewers make large yeast starters to get their beer fermenting fast. Large populations of active yeast help ensure flavorful beer free of off flavors.

Our 1000ml Erlenmyer Flask is the ideal vessel to make a large yeast starter for 5 gallon batches. 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

1L (1000mL) Capacity
Made from Borosilicate Glass
Fantastic price for a flask of this size
Produced for MoreBeer!

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.

Fits our stopper 8 (FE455)
