it is very interesting. yakima valley describes saaz and kazbek very differently.
Released in 2008, Kazbek is a Czech variety selected from breeding material originating from Russian wild hops and a noble Saaz parent. Named after the highest peak in the Northern Caucasus mountain range, Kazbek is a "super Saaz" of sorts, building on its
Czech heritage with a more expressive profile. It leans into bright citrus with grapefruit, lemon, and lime, layered with sweet fruit, berries, and subtle notes of cream caramel and spice. Kazbek offers dual-purpose utility, but is commonly used in late additions and dry hopping where its pleasant character shines without overpowering.
Saaz is the famous aroma landrace variety originating in the Czech area of the same name. Considered the world-standard of fine noble hops, Saaz boasts pleasant notes of bergamot, honey, cedarwood and chamomile — flavors that find a good home in lagers and pilsner styles. Saaz is also a breeding powerhouse with many strains and descendants, a renowned flavor that remains influential across the globe. A quintessential hop that has defined the beloved Czech-style pilsner.
OOof the current crop of saaz is at 1.7AA...that is brutal. still the same price thought.
Sladek is not even listed on YVH czech section. it is not even on their website if you search it.
