Spittoons - in a friendly wine tasting We sometimes do a friendly wine tasting. The idea is to discover good, well priced wines available locally - something that you might not have bought yourself.  Everyone brings a bottle, they are taken away by who ever is acting as sommelier for the evening, and then given a number. So, the whole thing is 'blind'.  Scores are given etc etc...  And eventual winners and losers announced (everyone also brings a small prize, so prizes are handed out as well).  The amount tasted is basically no more than a thimble or two,  there is no spittoon.  Would we get different results if we did, or is it OK to do this in our friendly tasting sessions.
The primary effect a spitoon would have, is less alcohol recpetion (some alcohol will get into the blood via the mouth-mucus). The alcohol could lead to different results for the later wines. 

You might get a more intense taste of the wine if you could take more of it into your mouth and "wash" with it. Even more if you take a sip, wash, gulp/spit, take another sip and taste.

Maybe you want to try it, when you drink a glass of wine next time and then decide if the bigger sips / double sipping makes a difference to you.

If it does but you dislike the idea of a spitoon, try reducing the number of wines per evening, so the increasing intoxication is not a problem.

I really like your version of private tastings and might adopt some ideas from it. Have fun!
