I had not been a cocktail drinker AT ALL until finding sansdrinks and the Lyre's range, so I have no idea what Espresso Martini are supposed to taste like. But I liked it, so that's a win.
The coffee flavoured one is very string (espresso), but I like coffee so that's a plus. The white spirit was also nice, and the combination as a martinus (one at at time).
As I move toward non-drinking (giving up on Ethanol) this combination might be a new way of doing so without having to stick to the beers I have been drinking in the past. New tastes for a new era.
