Aroma & Flavour, PHA® Hop Flavours
Botanix has developed a range of sophisticated physical separation techniques to fractionate the flavour compounds present in the hop essential oils. This allows the brewer to use the existing hop flavours more efficiently and also to create individual beer flavours. These products are fully soluble in beer.
PHA® Generics contain single hop oil fractions that create a versatile flavour and aroma palate; often used as a mixture (PHA® Spicy, Citrusy, Floral, Herbal and Sylvan).
PHA® Varietals are produced from a specific hop variety to reflect its individual characteristics (late hopping character).
PHA® Topnotes are similar to Varietals but contain more highly volatile, hydrophobic components, so they give a more intense Hop Aroma to beer (Dry Hopping Character). They have much more effect on the aroma and less on the taste.
