What is "malvesey"

Usage examples of "malvesey".

Howbeit, as the beer well sodden in the brewing, and stale, is clear and well coloured as muscadel or malvesey, or rather yellow as the gold noble, as our pot-knights call it, so our ale, which is not at all or very little sodden, and without hops, is more thick, fulsome, and of no such continuance, which are three notable things to be considered in that liquor.
