It's not quite the same as direct donations and all and feel free to delete if inappropriate, but I have some dealings with this company (as a buyer) and they're a really good bunch, I have nothing to personally gain from posting this link, or from any sales, nor am I paid by them in anyway shape or form (money, favours or other). It is just simply that having seem them and their set up, dealt with them directly (they're a small distillers, independently owned and run), I'd actually trust that all proceeds won't go straight into their pockets.

The same applies for a micro brewery which I'll post up if I can find their product (and if this is acceptable).
