Sorry mate,
I don't think straight Viura works at the budget level. It needs expensive oak and best ripe friut, sometimes mixed with malavesia (spelling) to give extra dimension
I've never had a reasonable cheapo Viura except in Spain, and when chilled right down is nice and refreshing, the oak comes thru as it warms in your mouth
In England, Ygay has been a fave, but now quite expensive, and better with food.
Looking at your favourites Ba, Avoid this in future.
