Are there better ways to sell more specialty beans and drinks for retail cafes?

[BIC]

when I say specialty drinks, I am not talking about Frappuccino or any espresso based drinks, like latte, flat white, cappuccino.

i am talking about v60, pour over, chemex with some good beans, different beans, natural, honey, with different species of beans.

almost 90% of retail sale is from espresso based coffees, is there any idea *marketing idea* that retail shops can promote specialty drinks?
