First Gold
Early brewing trials indicate that First Gold is an extremely exciting prospect. The variety is very suitable both as a general kettle hop and also for late and dry hopping in all types of beer. First Gold has excellent aroma qualities and much of the flavour character of WGV seems to have been retained, producing a well-balance bitterness and a fruity, slightly spicy note in ales. Considerable areas of First Gold are being planned and there is significant interest already from Britain's traditional ale brewers. |

The
analytical values are typical for each variety at harvest time but
values can vary among crop years, growing areas, growers, and with
aging after harvest. * Alpha Acids are determined by conductometric titration (EBC 7.4) in Europe. Alpha Acids for extracts are determined by HPLC (EBC 7.7 )in Europe. ** Storage is percent transformation after 6 months at room temperature.
