Going back to the low/free alcohol swaps; I've now sampled all the options available at Morrisons (without buying a dozen).
Guiness 0.0 - is nice, and tastes kinda Guinness-like, perfectly acceptable as is. I've found that having an actual Guinness first, means I can then have 3-4 0.0s without a problem (useful during the 6N)
Big Drop Brewing Co. Stout - probably nicer than the Guinness one, but weirdly, doesn't work as well following a real Guinness.
Erdinger Alkoholfrei Alcohol Free Wheat Beer - IMO, comfortably the best of the beers I've tried - it actually tastes like... lager. Perfectly acceptable alternative
Brooklyn Special Effects Alcohol Free Lager Beer - It's a reasonable soft drink in its own right; but not really an alternative to lager.
Northern Monk Alcohol Free Holy Faith Hazy Pale Ale - It's a reasonable soft drink in its own right; but not really an alternative to lager.
Doom Bar Zero Amber Ale - This was disappointing, as I like proper Doom Bar - it's okay, but... I guess it's more beery than the Brooklyn, Northern Monk or Big Drop, but... I guess I expected more.
Big Drop Brewing Co. Pale Ale - It's a reasonable drink in its own right, but you've got to like the taste of pine needles.
St Peters Without Gold Alcohol Free Beer - WTF is this travesty?
Morrisons Low Alcohol Cider Bottle – Tastes like British Cider - perfectly acceptable alternative.
Stowford Press Low Alcohol Apple Cider - Tastes like French Cider - it's okay, but it's missing something, for me at least.
Brothers Alcohol Free Various Toffee Apple / Fruity Ciders - Tastes pretty similar to the alcoholic versions, sugar and artificial flavourings. If you like the full versions, you'll like these.
