Hefeweizen Brew Day

I decided to do a single decoction mash for the inaugural House Hefeweizen.

Heated strike water to 128 and infused 40 quarts of water. Rested mash for 30 minutes at 122 degrees.


Raised temperature to 155 for 45 minutes. Mash ph around 5.3. Pulled 12 quarts of mash and boiled for 15 minutes.

At this point my dad put on some German music, since we're making a hefeweizen in traditional Bavarian style.

Poured the decoction back into the mash tun and began sparging. My potentially uncalibrated refractometer indicates the first runnings are 1.050 or so. I didn't use any rice hulls. I intended to, but the wort was running so smoothly through. Wort collection took about 20 minutes, no big deal.


Ended up with 13 gallons of 1.040 PB OG beer.


I did a really hard boil to get rid of any DMS.

After 90 minutes, I started cooling wort with well water. Hit 120 after ~7 minutes. Cracked open a single hopped, Belgian Columbus Hop IPA to drink during cooling and transfer. Columbus is a surprisingly versatile hop!

Stirred about every 3 minutes and recirculated wort through constantly with my march pump and silicone tubing. At 100 degrees, switched over to recirculating pump with icewater through the wort chiller.


Started transferring to a sanke fermenter at 65 degrees. Aerated with pure oxygen and pitched a 3 L yeast starter of Wyeast Weihenstephaner #3068

OG: 1.050
