at Tesco

A visit to Wales allows a check on Tesco's offering, and it was much better than expected.

Suffolk's St Peter's Without (<0.05%) available at £1.30 for 500ml. On taste, it is ok: not as beer-like or as pleasant as as Nanny State and somewhat reminiscent of that old (not) favourite Kaliber. Most of all, it tastes like a brewery smells.
Lovely bottle.

They also have Eisberg Cab Sav at the same price as Amazon, currently £3.

Dry Drinker

While stocking up on Nanny State at my local Sainsbury's, I got into conversation with a fellow queuer who mentioned the Dry Drinker web site. They even have alcohol free spirits.

At the time of writing, they are promising as "Coming Soon" a collection of Premium Craft Ales, though at a prospective £29.99 for (presumably) the 12 bottle option plus £6.99 delivery charge, that does seem expensive compared to Sainsbury's £1.29 for Nanny State.

Nevertheless, the site might be useful for looking into what is available. There are examples below though, again, the price of the red wine is more than twice what Amazon is charging for Eisberg.
