  • Use along with an 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.

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

G & F 1689L Heat Resistant Glove Commercial Grade, LargePictured: 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.
  • Search Amazon for “heat resistant oven glove”
  • Search Amazon for “heat resistant waterproof silicone gloves”

6 Pack of Magnetic Stir Bars by SEOH.  PTFE 6 x 25 mm (about an inch).

More Info

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

A general purpose stir bar that provides better mixing than cylindrical stirrers. An Alnico V magnet is encapsulated with a two step process, compression and isostatic encapsulation, to eliminate cracks and porosity. Each stir bar is polished to reduce the potential for contamination. PACK OF 6


 

  • Use along with an Erlenmeyer Flask and Stir Plate to do Stir Plate Yeast Starters.
  • What are others saying?  Search this product’s Amazon reviews for “brew” – may include reviews for other sizes or variations
  • 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 6?  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.
  • I have this stir bar and it works great.The vortex to the right was created with the help of this stir bar.  See: The HBF Stir Plate Mounting-Thingy for more info.
