Maris Otter Pale Ale
Malt
Golden Promise is a heritage British two-row spring barley variety, often compared with Maris Otter for its rich flavour. It was first recommended for growing in Scotland in 1968 due to its short, stiff straw and with even, but relatively small grain; characteristics that made Golden Promise particularly suited to malt production for distilling. Consequently, it was the dominant barley variety grown in Scotland in the 1970s and early 1980s. Golden Promise continues to be popular with craft brewers and distillers, and as such it is grown under contract in order to ensure its continued availability and is therefore at a premium price.
