Massive Yeast Starter

Yesterday I started making a massive starter for my first brew of the year. I essentially followed the instructions in this link (but used liquid extract instead) – Midwest Supplies

  • 3 (454g) jars of malt extract (1 unit DME => 1.25 units Liquid Extract).

  • 1 teaspoon of yeast nutrient.
  • 4 Litres of water.
  • Warm the water to a gentle boil adding the extract and the nutrient.
  • Gently boil for 20 minutes

gently boiling wort

  • Cover pan with lid and foil to keep it sanitised.
  • Sanitise glassware to hold starter.
  • When the “wort” is cool, transfer to sanitised glassware, ensuring there is plenty headspace. I ended up using six vessels as I was making a large starter with two yeast strains.

wort transfer

  • Blend the yeast into the cooled wort and ensure it is distributed evenly throughout the wort.
  • Loosely cover the glassware with sanitised covers (foil in my case) to let oxygen in, but keep falling airborne bugs out.
  • I cover the glassware with a towel to keep out the light and store in a warm place for the starter to grow.
  • Wait…

Yeast Starter 099 and 575

  • Now I’m stepping this up with a new OG 1.040 wort load. I’ve drained off the old “beer”

Step up
