Use Heat Resistant Gloves for Minding Yeast Starters & On Brew Day

Pictured: G & F Heat Resistant Oven Glove via Amazon

Part of Our Homebrew Tips and Tricks Series. Check out the complete list – Homebrewing Tips, Tricks & Shortcuts! This is a Top Post! See: All Top Posts

I use a heat resistant oven glove when I’m making yeast starters in an Erlenmeyer Flask. It’s really handy (pun intended) to swirl around the flask or to quickly remove to keep the flask from boiling over.
These are also handy on brew day for handling hot, (but not wet) ball valves and such.
A lot of these types of gloves, including the pictured model and the ones I use are not waterproof. As such, they should not be used with hot liquids.
Some silicone models are available that may offer some water resistance. Generally speaking silicone gloves are going to be less flexible. That may make it harder to pick things up. You’re trading off some water resistance for grip.
Safety Note: Always use caution when handling hot items or ingredients and always read and follow manufacturer directions.

INTLLAB PTFE Magnetic Stir Bars, Assorted Sizes, 7 Count… $5.99, 96 cents each, best price + free prime ship

INTLLAB 7pcs/Pack Mixed Size PTFE Magnetic Stirrer Mixer Stir Bars Type-C

More Info

Use along with a compatible Erlenmeyer Flask and Stir Plate to do Stir Plate Yeast Starters.
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.
Why get 7? Generally, you’re going to save money buying in bulk. Having these on hand allows you to do multiple starters at once and… you’ll have spares if you mistakenly dump your stir bar into your fermenter.

This assorted pack is nice because it allows you to try multiple sizes to see what works best for your setup.

6/17 6 AM Central: These are on sale for just $6.99. That’s the best historical third party Amazon price I found, notwithstanding Lightning Deals or coupons. Shipping is also free to many US addresses with Prime Membership [Try Prime for Free] or a qualifying order. Prices and availability can change quickly.

MoreBeer 2,000 mL Erlenmeyer Flask – $19.99 + Free Ship Eligible, Limited Availability, Matches 2020 Deal

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.

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)
