This is a tough question to specifically answer as everybody has a different pallet, idea and want in coffee. Any coffee will be great as an iced coffee.
Porter St Blend can make your iced coffee a little stronger, it cuts through the milk nicely. But, it's up to your pallet and preference.
If you want something lighter and a little more fruity, Trailblazer is great! Something with a spicy kick, you may choose Pioneer. If you would like to be adventurous, why not try one of our single origin offerings? https://pabloandrustys.com.au/collections/beans-single-origin
