It's a shame that the producers of that kind of cider are the least likely to do online sales. A friend and I have been making and selling cider since 2008. In 2010 we bought three acres and planted 350 apple trees (three quarters are trad cider varieties). We make around 2000L a year in the time we have available but have enough apples for two to three times that. We have made rum cask and whisky cask, but usually use ex-Bordeaux red wine casks. Our ciders are different every year because we don't follow a recipe and we allow naturally-occuring yeasts to do the alcohol fermentation. We also let them brew all the way so they are strong (around 7% usually) but dry. Bone dry. One review on Untappd suggested 'think Atacama desert'. The colour is down to the varieties you use and the cask. The first time you use a Bordeaux barrel (they only use them for three years) the cider comes out pink. Varieties like Yarlington Mill naturally give a darker colour.
Anyway, during the early years we spent a lot of time in the West Country learning our craft by meeting the makers and sampling lots. Here are my recommendations for non-commercial cider and perry makers:
Kevin Minchew http://www.minchews.co.uk/ in Gloucestershire. Kev is hooning mad in a nice way.
Derek Hartland https://www.facebook.com/ciderandperry/ - Also Gloucestershire and like stepping back in time. He sells Mills and Boon books and cassette music tapes, and he wears a Queen's Silver Jubilee pinny. Also a bit bonkers.
Mike Johnson https://rosscider.com/ - Mike was so helpful and makes great cider and perry. He has won awards for helping starters in the cider business. Fantastic guy.
Roger Wilkins https://twitter.com/wilkinscider?lang=en - Mudgley, Somerset and what a character! There are always red-faced old men drinking here, even at 10 in the morning. Try his cheddar and his blue cheese.
Andrew Heck https://www.heckscider.com/farm-shop/ in Street near Glastonbury.
Gwatkin Cider https://gwatkincider.co.uk/ - like stepping back 100 years and getting cider made by ZZ Top. They are incredible cider makers, I don't think they have one in their range that I don't like. My fave is the Somerset Redstreak when they have it. Try their Cheddar. Monumentally aged with salt crystals in the middle OMNOMNOM. We once asked for a VAT number when buying some cider and he thought about it for two minutes, then said, "Ain't got none... don't want none" in the darkest West Country accent ever. Avoid the Geese.
Westcroft https://www.westcroftcider.co.uk/ more Somerset loveliness made by an interesting character. Janet's Jungle Juice has won Best UK Cider three times.
This list isn't exhaustive by any means. There are many more great cider makers, and all over the country. We are in the Northern Cider Makers group which has forty members. Always be sure to check they use wild yeast, don't add anything, and use trad methods.
Cheers, that's a great list - I'll have to try Gwatkin and Wilkins. Do you sell any of your own stuff online?
