Although the label is Spanish, I also found out that its also Italian, meaning -- four. I don't have an idea where branding gets the label from, and I don't see how the number relates to a matcha chocolate cookie.
Quattro was worth a try, I would buy it again, once I run out of stock. I has a distinct taste of a strong matcha. It didnt melt in my mouth, but it my tongue! :P The white portion you see is a biscuit while bitter-tasting cocoa is sandwiched with the matcha chocolate. Good thing they always come in individual packs so I couldn't devour them all at once!
