Actually that's quite a good idea - we've some sherry glasses that must be not much bigger than that, I'll try using those. Won't get much nose from the wine, but hopefully enough.So I use 60ml glasses and typically half fill them, strangely that seems to work at helping me sip it).
In the UK it doesn't help that pubs have three different wine glass sizes. Most use a 175ml (quarter bottle), but some can give you a 250ml (third of a bottle) without asking. Normally the 125ml (sixth of a bottle} you have to specifically ask for.
A third of a bottle of 14% Malbec is quite a hit of alcohol and needs to be treated with caution, some of the New World whites can approach that as well.
Couple that with the wide range of beer strengths on draught - between about 3.4 and 6%, then it's easy to lose track of what you're drinking alcohol-wise.
With high INR ranges, us valvers need to be careful of taking knocks whilst a bit boozed up - mine sits between 3 and 4 so I wouldn't like to bash my head!
