i'm not sure about that. some variation of chico, but behaves differently is what I understand.
here's a decent review:

if you don't want banana and clove, and you don't want ester neutral, its a tasty option and adds some refreshing fruity ester to your beer.
I don't do many wheat beers so I didn't open this, but now did and have some contributions.
BRY is the Siebel yeast bank code.
BRY-97 is the dry equivalent to WY-1272 and WLP-051. These are said to be the Anchor Ale strain.
BRY-96 is the same as US-05/WY-1056/WLP001 and is the Chico strain.
Both are from Ballantine, 97 being the ale strain, 96 being the beer strain.
The Widmer brothers went to Germany before they opened the brewery. They were going to have an Alt as the flagship, spent time at Uerige, and brought the Uerige strain back (Wyeast -1007/WLP-036). The Alt never took off, but they brewed a wheat beer that did. The yeast became less flocculant at Widmer, and is Wyeast 1010/WLP-320. The description on the Fermentis product sheet for K-97 says it is a German ale strain, so with that and the 7 I would guess it is the same as WY-1007. Anyone know more?
Microbiologists will talk about yeasts that have the POF gene - Phenolic Off Flavor. The German wheat beer yeasts and many Belgian strains have the POF gene. Other ale yeasts and lager yeasts do not. Clove flavor is a phenoic, the banana is an ester.
The one American wheat I did last year was a Bell's Oberon variation. The Bell's yeast can be captured from the bottle and propagated. It can give an orange ester if you ferment at higher temperature, high being 70F or so.
Torrefied wheat has given a nutty taste to my Bitter, I like it. It is a puffed grain, as it is heated to about 500F until it pops like popcorn.
Golden Promise is a great malt. It is not kilned as high as most Maris Otters. GP is 2L from Simpsons and 3L from Fawcett. Simpsons has a nice sweet malty flavor. I have had beers made with low color Maris Otter at 2L, and those have a malty sweet flavor. Notice the taste is more malty and less sweet with MO.
Sunday morning, drinking my coffee, rambling away.
