Eureka, another wheat recipe from the past. This recipe is the same as batch #28 Helles Weizen and the second batch for the wheat yeast comparison experiment. I compared four different yeast strains in this batch. The rest of the batch was used for a Orangenweizen (with oranges) and a “normal” wheat batch fermented with the #3068 Weihenstephan for normal drinking purposes.

05/01/2011: Brew day. The lautering was a real trouble maker. I could not get a clear wort for nearly a quarter of an hour. I gave up trying and begun to collect the hazy wort and hoped to get rid of the sediments in the whirlpool. To be sure that no sediments get into the fermenter, I used a mash bag to filter the wort after it went through the chiller. There weren’t much residuals in the bag after filtering. So I filled up the little fermenters for a second time and let it ferment. Used two buckets again for a backup if one of the fermentation would not be okay.
I used the rest of the batch for an experimental Orangenweizen, and for a normal wheat beer fermented with by the #3068 Weihenstephan yeast.
05/11/2011: Bottled the beers as they reached the terminal gravity already. Added sugar to the bottles and the huge bottling marathon begun for a second time. Left the bottle at room temperature for two weeks for bottle conditioning and stored them for three weeks in the refrigerator before tasting.
June/July 2011: The tasting begun. Results are in the report about the wheat yeast comparison experiment.
