Polypropylene keeps your coffee fresher and tastier

What’s the secret to good coffee?

It has to be fresh.  The coffee, of course — nobody wants a cup of coffee that’s been sitting around all day.  But the beans too.

And if you make your own coffee (yes coffee house culture is a thing but many of the true coffee connoisseurs drink home brew) — keeping the beans fresh starts with the bag.  Also true if you buy your coffee already ground.

Inside that bag is the secret — a hard-working, thin lining made of polypropylene — keeping air out, and your coffee goodness in.

Coffee, of course, grows on a bush — but polypropylene, we had to invent that.  Luckily, in 1954, we did.  And how important was that?  The two chemists who figured it out, won the Nobel Prize in Chemistry (not for making better coffee bags, but for some of the chemistry needed to produce that polypropylene).

Polypropylene IS a human-made product, but it’s made from something 100 percent natural:  oil or natural gas.  When you process either of those at a refinery or petrochemical manufacturing facility, chemically speaking, you get propylene — which is the raw material for polypropylene.

Polypropylene is a mouthful, but why it’s good for coffee beans is simple:  it keeps out air, (keeping your coffee fresher), it doesn’t react with what’s in it (so it’s safe for food), it can be made in light, thin sheets (so you can line a bag with it).

So whether you make your coffee this way…

This way…

…or this way…

…a better cup of joe is in the bag.
