For a long time now I’ve been trying to be more conscientious when buying anything, which of course includes beer. My focus has been on social and environmental stewardship. (After all, voting with your dollar seems to be the only way to influence real change!)
The problem with the cheaper beers is that they’re mostly beer-cordial owned by massive foreign corporations with more focus on profit than product. (Would you rather drink fresh local fruit juice, or juice concentrate from who-knows-where?!)
As @NdeViser mentions, Stone & Wood are pretty good! They’re one of the few breweries which are part of B-Corp. (An independent accreditation for profit businesses that meet rigorous standards set around governance, workers, community, environment, and business impact models. It certifies companies that are concerned for their communities and the environment.)
But what’s even better? Brewing your own beer. Companies like Small Batch have these little kits which are super easy to follow and give you whatever beer you want to drink. Learn to brew beer with one of their own recipes, then you can modify the recipes to suit your taste. The grains which are left over get dried in my oven and are included in my home made sourdough bread - so tasty! Nothing goes to waste.
Really happy to share techniques if anyone is interested in trying this out.
