FLASK 1000ml - ERLENMEYER

Flask Erlenmeyer - 1000 ml

• Many brewers will state that making a yeast starter is essential for proper pitching rates and reducing lag time when fermentation begins (which may greatly minimize the chances of bacterial infection in your batch).
• Plus, using starters will supply more yeast than your standard vial or package.
• If you want to put a stopper on your 1 Litre flask, the right size to use is #8.
• This 1000 ml (1L) Erlenmeyer Flask is the ideal vessel to make a yeast starters for 20 litre batches!
• This flask is made from borosilicate glass, which means it can be moved from a boil on your gas stove to 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.)
• With flasks, your yeast starter process can be completed all in one container.
• This not only keeps things simple, but the fewer the containers, the less risk for contamination.

Recommended Use of Flask

• The "Double Boiler" Method. This involves using a boiling water bath on the outside of the flask to heat up the water/wort on the inside.
• All that is required is a kettle 10 litres or larger.
• This is a safer and more efficient process.
• If the flask should ever break or boil-over, your kettle will be there to collect the contents while keeping your stove clean, and keeping you away from potential harm.
• This method keeps the heat distribution even throughout the flask.
• Direct heat, non-even heat distribution, to the glass can break down its integrity over time.

Why make a yeast starter?

• Yeast starters ensures healthy yeast.
• By creating a yeast starter 1-3 days in advance of your brew day, you ensure that your yeast is healthy and strong enough to do its job.
• Secondly, the starter creates more yeast.
• This increase of the cell count will give you a better chance of keeping bacteria's and wild yeasts from fermenting in your wort.
• If you are planning to brew a high gravity beer (1.060+) you will need more yeast to start the fermentation faster.
• High gravity beers will also have a better chance of completing fermentation with ample quantities of yeast (less chance of stalling out).

• To be used with a #8 stopper
• A great flask for making yeast starters!
• (In the lab world, these flasks are known as "Student Grade". Student grade is not the highest grade flask and will have minor defects).
