Cloudwater

2019 update: The shop got a refresh at some point and there are several notable improvements. The switch to using Shopify has made the site even easier to order from. Changing the courier from ParcelForce to APC is a huge improvement in delivery reliability and speed. And finally, free shipping when spending just £35 or more is pretty easy to reach.

The brewery I've most frequently ordered from directly. Website is easy to use and very well designed. Selection is of course limited to their own beers but they usually have 10+ in stock so you can comfortably fill a box with mostly different beers. Pricing is generally decent, hard to find any bottleshops selling cheaper than the brewery themselves.
Orders are usually dispatched next day and delivery is next day too, can't get much quicker than that. Packaging is good, not the strongest of boxes I must admit but they are perfectly sized for Cloudwater's cans so there's not much room for movement which is good. Very responsive on email and social media with queries and issues so no problems anywhere really.
