Won't see it with Scotch whisky -this must be a minimum of 40%. Also, because you water spirit down with whisky, I imagine the tax arrangements for the alcohol produced are somewhat different to beer/ciders where the alcohol starts at 0% and is created.
Odd you should mention it, but it was only a gentlemen's agreement that kept spirits at 40%. There is now a legal minimum but it's 37.5% (I think the EU must have been involved to actually arrive at 37.5). Generally most spirits are 40 or above but the supermarket own brands are usually 37.5%.
As for the question, just count the total amount of Stella you drink and ignore the Lemonade.
