Aurora and Celeia are both Slovenian hops born out of the breeding programs in Slovenia that tend to get very little interest. Slovenia has been slowly feeding styrian varieties into the world but they tend to be overwhelmed by interest in new German hops on the European side and all of our American and southern hemisphere hops from the new world. The Slovenian hops unsurprisingly provide good attributes for lagers with smooth bitterness and mellow flavors. However, there are some interesting flavors across the different varieties that make them more useful than just bittering.
Aurora HopsAurora was originally known by its name Super Styrian when it was developed in the 70s. It is one of the two most grown varieties in Slovenia (Styrian Goldings being the other). It is a cross of a native wild male and a female Northern Brewer so it is actually unrelated to Styrian Goldings. It shares some of the attributes of Styrian Goldings but unlike Styrian Goldings it is a high alpha hop, which makes it an effective bittering hop. It has low co-humulone, which makes for a smooth bitterness desired in lagers and other European beers. However, it has interesting flavor and aroma attributes that make it an interesting late or dry hop addition.
Aurora features flavors popular in New World hops with a unique twist. Aurora is big on citrus punch, floral notes, pineapple, mango and a heft of spice and herbal character expected out of the styrian family of hops. What makes it unique among many of the desired tropical-flavor hops is that the flavors are undeniably present without being aggressive. The herbal/spicy character helps keep Aurora in check compared to American or NZ/AUS tropical hops that are more assertive. That balancing effect makes Aurora a good beer for lager styles where the brewer wants some of that citrus character without the hops bowling over the malty smoothness. It might be the best hop out there for the new hoppy IPL style. It also works well for saison, pale ales and would do nicely in a mix with other hops in an IPA/DIPA.
Celeia HopsCeleia, aka Styrian Celeia, is a daughter of Aurora, Styrian Golding and a Slovenian wild hop. Unlike Aurora, Celeia has low alpha and low co-humulone, so it is a suitable hop for European styles looking for a gentle bittering charge without the sometimes pricy cost of noble varieties. Like Aurora, it comes out of the Slovenian hop fields and shares the herbal/spicy/citrus character of the Styrian family.
It is definitely a different hop than Aurora. While Aurora has a well-balanced mix of flavors, Celeia is slightly more aggressive in aroma and flavor. It is also less complex, with assertive notes of lime, floral and an herbal background. The lime and floral dominate, making it an unusual mix of flavors. It's a hop without many great homes, unfortunately. The herbal notes are slightly too noticeable to mix well into a hoppy ale with a fruit forward character but way too fruity for a dank beer. It's too flavor aggressive for many lagers. I suppose it could work well at low volumes. It does ok in saisons when blended with other hops where a little herbal character is welcome among a lot of fruit. It plays acceptably with Aurora although the combination really pushes the floral notes in a way I don't exactly love. A mix with Opal seems to restrain the lime and floral. I am sure other herbal/spicy/grassy hops would help bring Celeia into line with more of a Styrian Golding or Mt. Hood profile.
