Not quite sure of the legal definition but my palate tells me its not a traditional brandy but they all fall under the heading of sprits and raki may well be classed as a brandy.
in my opinion arminiac is the best of the family of brandies and this is due to style of distillation.
ARminiac is distilled gently to the correct proof and the distillation is stopped.
BRANDY is the same process but slightly overdistilled then watered back down to the correct proof.
BOTH arminiac and brandy retain some of the aromas and taste given by there original fruits
further down the chain are drinks like Slijivovica, the hungarian equivalent of raki which is made traditionally with plums and although it is distilled vigorously it still retains a discernable flavour
raki on the other hand is distilled with not much control and like vodka and is made out anything or a mixture and can range from tasteless to cats pea but is certainly an ice breaker .
best thing to do is just call it raki so when you ask for one you don't get give expensive imported rubbish but the real thing
