While 16 tasters (p<0.05) would have had to select the unique sample to reach statistical significance, a total of 19 (p=0.002) identified the odd-beer-out, suggesting participants were indeed able to reliably distinguish a Hefeweizen fermented with WLP300 yeast at 60°F/16°C from the same beer fermented at 72°F/22°C. Sulfate(SO4): 54.0 ppm ----- Even with the same yeast strain, slight variations in fermentation temperature can produce profoundly different results. Not much else to say except that the thick head helps trick my tongue into thinking the beer is fuller/creamier than it is. The recipe I used for this xBmt was pretty standard for a Hefeweizen. Amazon Find the sweet spot where the yeast generates the flavors you desire in your finished beer, dial in the temperature, and keep fermentation in a narrow temperature range. Grain/Extract/Sugar My Impressions: I attempted 3 semi-blind triangle tests with these beers, each time the unique sample being randomly assigned, and I was able to make the correct selection fairly confidently each time. Each participant was served 2 samples of the cool ferment beer and 1 sample of the beer warm ferment beer then asked to identify the sample that was unique. Profile: Washington DC ), count me in for more Belgian/Hefeweizen strain xBmts. Witbier is the Belgian version of wheat beer. Ferment at 62 °F (17 °C) until the beer attenuates fully. Hydrometer measurements taken 6 weeks post-pitch showed both the cool and warm ferment beers had dropped to the same FG. Chilled down to 71, strained out hops, put into chest freezer at 55 at 4:30 PM. The very strict rules in Germany stifled wheat beer innovation. 3.50 lbs. When the boil was finished, I quickly chilled the wort to 72°F/22°C. My assumption is that by the time you racked to kegs and carbonated, the warmer fermented beer was able to “catch up” from a clarity perspective. Magnesium(Mg): 9.9 ppm ... WLP380 Hefeweizen IV Ale Yeast. As any brewer of the style knows, achieving these characteristics demands the use of a particular type of yeast, one like White Labs’ WLP300 Hefeweizen Ale yeast that hasn’t been selected to exclude the POF+ gene. Based loosely on Live Oak Hefeweizen. Anticipated SRM: 2.9 Sign up to be notified when we publish new content! Hops adjusted down from 2% AA because they are a year old. Adventures in Homebrewing At Westmalle, yeast is pitched at 64 °F (18 °C) and rises only to 68 °F (20 °C) during fermentation in closed squares. Marshall, Im curious about the volme of the decoction you boiled each time. In fact, if you repeated every fermentation experiment with a belgian strain, I would read them all. So a little little a fermentation note about this beer. To evaluate the differences between beers fermented with WLP300 Hefeweizen Ale yeast at either 60°F/16°C or 72°F/22°C. It is one of the fasted beer styles from mash tun to glass so I thought it was a good one to brew near the start of the brewing season (even though it isn't exactly a classic cold weather beer because it is so light and drinkable). All right, so its tasting time, I have Andy with me fresh off the boat as it were from England. Diluted down to 7 gallons because efficiency was better than expected. Brewer’s Hardware Therefore I’m intrigued how much of the significance is owed to directly pitching the vial thus slightly underpitching the yeast. Brewhouse Efficiency: 71 % The cup color for the unique sample is always the same, the cups are presented to each taster randomly (e.g., one taster might get red-blue-green, another might get blue-green-red, etc). Due to the open fermentation at the home brewing scale, banana-flavored beers can be produced without significant technological adaptations. As I usually brew belgian ales with POF+ strains, I’ve always felt that fermentation temperature makes a big difference. Very active fermentation for 72 hours. ------- I was very glad to see this. The cooler fermentation temperature helps fine particles bind and settle out.
