Two New Open Source Hop Varieties, Callista & Ariana

Three weeks ago, the people who created Mandarina Bavaria, Hüll Melon and Hallertau Blanc announced that they have done it again with their release of Callista and Ariana.  These two new varieties both have amazing characteristics, but could not be more different from one another. Something for everybody!

With low total alpha acids (2-5%) and a low cohumulone (15-21), Callista will appeal to brewers who prefer a classic noble hop variety characteristics with traditionally smooth hoppy notes, but who have been craving a fruity profile to take advantage of current trends. Callista has apricot, blackberry and raspberry notes when in its raw hop form. In brewing trials, some of the flavors it imparts are passion fruit, peach, grapefruit and gooseberry depending upon usage and the type of beer brewed. Only several commercial-scale fields exist at the moment. For growers, Callista appears to be a desirable variety to grow. With large cones and powdery mildew resistance, Callista will be relatively easy to pick.

At the other end of the scale, with total alpha acids between 10-13% and a much higher cohumulone of 42, Ariana will appeal to brewers looking for very different characteristics from a hop, but one that results in a similar flavor profile.  In Ariana raw hops, you will pick up black currants, peaches, pears and tropical fruit notes.  Depending upon the style of beer brewed and timing of the addition of the hops, brewers have noticed grapefruit, gooseberry, citrus and vanilla flavors. Ariana is said to be ideal for dry hopping, when it imparts its most intense fruity flavors.  With a high yield and late maturity, this variety will fit nicely into growers’ picking schedules.

If you’re in Philadelphia for the CBC, you can taste the varieties for yourself at the German hospitality suite. They will have single hopped beers brewed with these varieties available and there will be raw hop samples there too. If you won’t be at the CBC, you’ll be able to taste them soon in a beer near you as these German hop varieties are coming to America. 47Hops is excited to announce that we will have most of the available production of these two new varieties beginning in 2017. We’re not reserving them only for big brewers, or for anybody in particular for that matter. Big brewers are welcome to them and so are small brewers.  We’ll even make some available to home brewers.  It’s first come first serve because that’s the only fair way to do it in our opinion. Supply is short though so we don’t expect these to be available for long. If you’re interested in them, send us an email at Callista
[at] or Ariana [at] and we’ll take care of you.
