Due to the Coronavirus / COVID-19 pandemic independent breweries and bottleshops need your support now more than ever. If you're considering purchasing beer please buy from independent businesses. The big guys will get through this crisis but independents are already struggling and we need to do everything we can to help them survive.
US visitors: We know online bottleshops aren't as common in your region of the world; if you don't find anything relevant here check out Megan's (@isbeeracarb) wonderful blog post listing a huge amount of breweries offering to-go sales sorted by state. Greg's List by Untappd is another excellent resource for bars and breweries that might not have online shops.
Support whoever you can.
