beer and brewing
Invercargill Brewery - Owned and operated by Steve Nally, arguably New Zealand's best experimental brewer (I'm not sure who would argue against this claim, but "arguably" sounds right). Steve was instrumental in getting Yeastie Boys from the backyard to you.
NZ Hops - Doing great things for the New Zealand craft beer scene. These guys sell 100g of hops to the novice homebrewer and container loads to US craft beer community.
