This is normally much more expensive than £1.75 for 4 (355ml) bottles as it's normally only seen in more specialist beer retailers.
This was see in-store at the Aldershot branch and I fear I may have cleared them out (but I have already passed on gifts of beer to friends), unless they have stock in the store room, and no idea if the product is available more widely.
However I thought this was worth sharing if people wanted to check in their local branches.
The description of this beer on BeerAdvocate is:
"Brooklyn Brewery 1/2 Ale hearks back to traditional farmhouse ales, which used to quench the thirst of farmhands and other laborers on hot sunny days. These saisons were complex yet clean, low in alcohol and high in refreshment.
Brooklyn Half Ale is an unfiltered, clean, and balanced saison, with a hazy, pale yellow pour. It packs a symphony of citrusy hops over a gentle malt base that clocks in at a pleasantly restrained 3.4% ABV."
