New Scotch Lover, A Few Questions

Hello everyone,

I've been getting into single-malt scotch for the past half-year (as long as I've been legal), and have already acquired 5 different bottles from different regions because the variations in them are fascinating to me.
I have a few questions though, and was hoping for some help.
What is considered the "right amount" for a glass? I've heard everything from .5 oz to 2 oz. It's probably preference, but I was wondering if there's a "correct" amount.
Also, It seems like the taste of a scotch can vary enormously from night to night. Is this common? should I cleanse the palate before tasting?

Thanks!

The Scotch Whisky Association refer to a standard glass as 25ml. Sorry I don't know how much that is in oz's but it gives you a figure to work with.

I must have double standards because I prefer 50ml

Whatever you feel you want to drink. Sometimes I pour a small glass, sometimes I pour a very large glass!
There is no correct amount, unless you are selling it!

Pour, drink, enjoy!!!!

A lot of bars in London pour you 50ml drams. At home, I generally just pour the amount I want, but it's often around that 50ml mark.

Which whisky do you have from each region?

Most London bars seem to be serving large measures (50ml), and I find that I pour roughly the same at home... be it a little more or a little less depending on how I'm feeling.

Which whisky have you bought from each region?

Glad you are getting into your whisky

Thank you for your replies!
After seeing what 25ml looks like, I pour a little less than that if it's something heavy and smoky like an Islay, and a little more if it's lighter like a Speyside (assuming an Islay can't be light and a Speyside can't be heavy... I don't have too much experience).
I have bought 6 different whiskies so far: Talisker 10, Laphroaig 10, Oban 14, Lagavulin 16, Glenlivet 12, and Cragganmore 12. I bought the Lagavulin because I really liked the Laphroaig and it's peppery smoky flavor, but I think I still like the Laphroaig better since the Lagavulin seems sweeter and not as peppery to me. Same with the Cragganmore, I bought it because I liked the Glenlivet but I actually like the Cragganmore a lot more in this case (I like the spicy/flowery/licorice flavors).
