    Default Math problem

    I want to ensure a lifsetime supply of Rive Gauche but also make some available to fellow Basenoters.
    I have 13 4.2oz tin cans. I wear it approx 4-5 times a month. I'm turning 49 on Halloween.
    How many to keep? How many to potentially swap?

    I would imagine that youd be fine keeping 5 or 6 bottles and getting rid of the rest.

    Average of 1,200 sprays in a 4.2 oz bottle

    If you wear it 5 times per month and use 5 sprays each wearing = 25 sprays per month

    = 300 sprays per year

    = 4 years per bottle

    If you lived another 25 years you would need to keep 6-7 bottles

    Now Smell This did an article on this years ago. While every sprayer is different, they found that you get about 735 sprays per 50 ml.

    So for a 125 ml bottle, you are looking at about 1,837 sprays.
    20 sprays a month means a bottle will last almost 92 months, which is a little over 7 and a half years.
    If you keep spraying for another 40 years, you would need 5-6 bottles to cover that time period.

    Let's be generous for the sake of argument and say that you will live another 40 years. 5 wears per month is 60 wears per year. Over the course of 40 years, you will wear Rive Gauche 2,400 times.

    Most bottles get anywhere from 10 - 15 sprays per ml. I generally assume you will get 12 sprays per ml. Consequently, each bottle will provide you 1440 sprays (120ml x 12 per ml). I don't know how many sprays you wear, but I'll assume it's 4 each time. Therefore, each bottle will provide you 360 wears.

    3,400 wears divided by 360 wears per bottle = 9.4 bottles. This would be conservative, and you might be fine with less.

    Also, I'm a bit curious how you ended up with 13 bottles of Rive Gauche! Did you just slowly acquire them, or did you buy in bulk when you heard it was being discontinued? Either way, it was a good choice. You can sell off your extras for a nice bit of cash!

    If you're not flipping them for the going market price, but rather closer to what it retailed for I'd love to take one off you. Always wanted to try it.

    I'm not looking to flip for money, I will be looking for fair value in swaps ie other desirable hard-to-find gems.

    You re being a bit optimistic I think. In my experience I get 8-10 sprays per ml, with «*great sprayers*» giving just 5-6. (No secret: a great spray = more juice sprayed).
    You also ignore the evaporation. Indeed, on a 125ml bottle used frequently, only 110-115ml will be effectively used. I think that an average of 800/900 sprays per 125ml bottle seems more realistic..

    Sorry everyone, I linked to the wrong article earlier. This should be the one where they test the number of sprays per bottle:

    I like this thread. It reminds me that 50ml of most frags is usually sufficent to last years.

    Of course you are assuming the juice never goes bad. 4 bottles may last 10 years. And 30 bottles may only last 10 more years, at which time you throw all the remaining stuff out. Just something to keep in mind.

    I'm optimistic about the longevity of the juice - the tin can means no light pollution.

    I'm more than content with my vintage purchases - some going back decades - to not be worried about frags going bad. They may lose some of the top notes but that's about it, in my experience.

    I like this thread.... but.... only a few weak things do I go 5 sprays but let's stick with that. 5 sprays and every day, 30 days a month to make it easy equals 150 so a 4.2 ounce lasts for eight months.

    Have too many bottles!!!! So need to start..... 1 - spray way more than 5 times or 2 - wear more than one a day or 3. - start supervitamins/exercise/supplements/build $ for treatments to try to live a lot longer..... or 4 - say f it and decide who gets them later

    Great math problem to have. I’d keep ten and if it looks like you can part with more later, do it. They’ll only be worth more later.

    4-5 times a month suggests 2 bottles would be fine, 3 would be more than enough. Anything more suggests hoarding just for the sake of it.

    I'd genuinely like to know the rate people finish bottles of fragrances without selling decants or whatever else - just through wearing, how long does a bottle last. Because, to me, age 50 (let's say 30 more years of wearing fragrance as a rough bet) and 4-5 times a month suggests he probably won't finish a single full bottle. I'd be intrigued to know if I'm in some kind of minority with regard to how long a bottle actually lasts.
