A dual purpose / bittering hop with classic resinous pine and lifted citrus characters (10-12%AA)

Breeding: 

Dr Rudi Brand 68-4-96 is a triploid variety that was bred from the New Zealand Smoothcone variety cross open pollinated at the New Zealand Horticultural Research Centre and released in 1976 as  Super Alpha. Officially changed to Dr Rudi in 2012. 

Selection: 

Widely selected for its dual-purpose ability, Dr Rudi was once a high alpha type.  Selectors note a fresh citrus peel beneath a mix of aromas such as pine needles and lemongrass when used as a late addition become evident in the aroma top notes.

Brewing: 

A very versatile hop in the brew house where it can be used to deliver a quality crisp bitterness as well as excellent aroma qualities. Typical of New Zealand varieties, the oil profile sets it apart as a hop with many applications and can now be found in breweries throughout international markets where it is sought for its ability to integrate and finely balance both Ales and Lagers.

"A really super hop!"

Applications: 

Works well where resinouscitrus and pine characters are required to build and develop an excellent finishing bitterness. Especially good as a dual purpose variety in single hopped beers as well as with multiple aroma varieties to create first rate new-world beer styles.
