Old thread but someone may get reassurance from my experience.
I've done this kit twice, first time I got 4.7% ABV, second time 4.6% ABV.
That's further off Young's claim than brewing variables would account for so I think their 6.3% claim is misleading.
It's a good kit though, although only...
When I started giving blood, back in 1977, you could choose a can of Mackeson as your recovery drink afterwards.
Nowadays, you get lectures about alcohol.
Guinness isn't even my favourite Irish stout.
I've drunk it all the way down the west coast of Ireland and it tasted the same to me. (This was thirty years ago though).
The West Indies Porter is far better.
Young's American Oaked Rum Ale
MJ Raspberry Berliner Weisse
MJ Bavarian Wheat
MJ Spiced Belgian Dubbel
MJ Orange and Cinnamon Wit
Munton's Taproom Lemon Radler
Bulldog Strawberry Pale Ale
Lots of MJ but I do lots of their kits and tend to choose 'different' stuff, apparently just so my wife can...
On the other hand, I will be doing this one again.
It's all a matter of tastes.
I've done forty-one kits now and only fifteen are on my repeat list.
I always brew to the instructions.
I did this one a year or more ago.
Always felt as if I'd drunk a pint of rum after one.
Couldn't find anyone who liked it, even a rum-drinking friend.
The only beer of the 36 brews I've done so far that went down the sink.
