The bottle cap is one of our standard Wychwood bottle tops and could be from any of our range of Wychwood Bottled Beers. Unfortunately we do not produce a non alcoholic beer. The January’S ale is only available in cask during January and this year is 2.8% abv. (this was 3.8% in 2011).
The lowest abv bottled beer that we produce is Brakpear Bitter at 3.4%, the next are Goliath and Ginger Beard at 4.2%
We hope that you are able to get the opportunity to try one of the above beers, which are widely available from most major supermarkets and if we can be of any further assistance please do not hesitate to contact us again.

So to sum up, there is no non-alcohol Wychwood, so I'm wondering if maybe it was the Gingerbeard (which is alcoholic but if you think "ginger beer" you might think it isn't). January'S ale (with the capital "S" that mad me think it was January Sale at first) has a alc. content that varies by the season and thus the discrepancy there, and the cap is their "standard one" which is about what I figured.
