You’re right about Newcastle. It was changed and brewed by Lagunitas for a while there. Everyone hated it. Imports from the UK started again a couple of months ago. It’s owned by Heineken, so you might be able to contact a distributor to find or request it. Sales were really slumping before the change so it might not have a super long life span with import costs. And yeah, people having more options have probably kept this one at bay for you. Same with Smithwicks. They are good beers but would need better sales to really become available to you.
