Ambar Triple Zero Tostada is the roasted-malt variant within Ambar's Triple Zero alcohol-free series, distinguishing it from the standard pale lager and radler options in that sub-range. It is brewed by La Zaragozana in Zaragoza, a producer with roots in non-alcoholic beer making that stretch back to 1976, placing Ambar among the earlier dedicated AF beer producers in Spain. The tostada character, derived from roasted malts, gives this variant a distinctly darker, maltier identity compared with its Triple Zero siblings.
