I’m planning a hefeweizen brew day in a couple of days so I got my yeast starter going today. I’ve only recently started using starters with good success and now I won’t brew a beer without one. Making a yeast starter is super simple and I’d like to share my quick recipe.
2 cups of water
1/2 cup of DME or 2/3 cup of LME
Stir in the malt extract and bring to a boil for about 10-15 minutes. While this is boiling, sanitize your flask or mini-fermenting vessel, stir bar (don’t sweat it if you don’t have a stir plate), funnel, bung, airlock, and the yeast pack/vial.
After the boil, chill the wort to about 65-70 degrees. If you have a refractometer, take a quick look and check the OG. You want to target no more than 1.040. Vigorously shake the flask, pitch the yeast and drop in the sanitized stir bar. Plug the flask with the sanitized airlock and place on the stir plate.
No stir plate? No problem. Just give the flask/vessel a gentle swirl every few hours. You should start to see some activity in the airlock in a few hours.
