Title: Three yeast examples
Post by: another1 on December 05, 2011, 02:46:15 AM
As part of my recipe development for a KiwiFruit Beer named "Patches MacKiwi" I trialled 3 different yeast strains on the same wort, the following video is the fermenting process that shows the differences, and the beer is soon going to be bottled, and the all important taste test results will follow soon.

FG results, and tastings
S-04 - 1.018
Clear color, and a crisp taste, the acidulated malt came through well on this batch, quite sharp.

US-05 - 1.016
Clear golden color, least turbidity of them all. sharp taste, clean and fruity

S-23 - 1.018
Cloudy, darkest out of them all, not a lot of flavor coming through, pretty flat

Overall from the first early taste test, the US-05 is the clear winner, as for the beer, it needs more body in it, it is very light, but the kiwifruit notes are present.

That's a pretty good achievement since kiwi is subtle in taste.

The acidulated malt helped a lot with the flavor. A previous trial batch was too bitter after the kiwi had fermented. So the sour really helped balance it out. It only needed  3% to the grain bill to balance the flavor. Still needs more body though, not a lot left on the palete.
