Since Alaskan Lupine ( Lupinus nootkatensis ) was moved to the country, it has been used almost exclusively for land reclamation. It has been interested in using it in agriculture, as feed or for grazing, but there has been a fall in the high bitterness content. The experiments that have been carried out indicate that this is not possible without the appearance of a cultivar or lupine being processed and bitterness thus obtained. Experiments have been conducted to indicate that the total alcohol content of the Icelandic Alaskan Lupine is in the range of 1-2% of dry matter and may contain up to 16 different bitterness materials, most of which are sparingly. The total amount varies but is accompanied by light and is therefore mostly during and after the summer solstice.Quinoline bituminous substances, their formation, their structure, their effects on organisms and their measurements are poorly accounted for. The results of bitterness measurements on Icelandic Alaska lupins are also published..
""People have been asking me where to find lupines in Iceland. If you like them you should be able to find them easily in Iceland in summer. They are in bloom and visible almost wherever you drive around the country, very often along roads and lakes""
