Nespresso Original Coffee Capsules: Buy 5 Sleeves, Get 1 Free: 60-Ct Capsules (various)

My brother own/ran a coffee shop for years so we got to test & sample many different professional & at-home machines as well as coffee beans so
5 insider/expert tips below (I own both super automatic Phillips/Saeco LatteGo 3454 & Nespresso Latissima+ )

1) The science of coffee & machines since I majored in biochemistry:
Regular drip coffee machines such as coffee pots & Keurigs have ZERO pressure;
French Press has about 20 lbs of pressure;
Aeropress has about 30 lbs of pressure

Espresso machines have much higher pressure --the standard mininum pressure for espresso machines that you find in Europe & 5-star restaurants/coffee shops is about
200 to 225 lbs of pressure PSI aka as
13 to 15 BARS of pressure for PROFESSIONAL machines used in good coffee shops/restaurants

Nespresso is at the high end with 19 bars of pressure -about 275+ lbs of pressure PSI

-- Jura; Saeco/Phillips;
WMF; DeLonghi; etc also all have mininum 13 to 15 bars of pressure or higher also for their professional & at-home machines

-- any machine that has at least above the mininum pressure/bars that will ADVERTISE IT --if they don't tell you how much pressure it has; then it's because it has below that --such as the Ninjas or Bella (I had to research them heavily to find they had only about 50 lbs of pressure)

2) Independent lab tests by food/coffee companies have shown that have the mininum 200+ lbs of pressure you squeeze out
&
extract over 900+ essential oils
&
each essential oil is a different flavor & aroma;
thus you are getting at least
900+ different flavors & 900+ different aromas from professional 13 to 19 bar pressure machines (200-275+ lbs of pressure)

This is why coffee shops/restaurants that use the above hi-pressure machines smell so good

3) You know how cutting open an apple & exposing it to air/oxygen; the apple turns brown from oxidation?

Same thing happens to coffee after you grind the coffee beans & expose it to air/oxygen
--Coffee grinds go STALE after about
20 MINUTES according to lab tests by food/coffee companies --this is why old coffee doesn't taste good
&
why you should always use your coffee grinds within 20 minutes of grinding your beans
--do NOT grind beans at the store unless you intend to use them within 20 minutes

If you order at a restaurant/coffee shop; make sure they grind the beans fresh or within 20 minutes earlier before you ordered &
NOT using the grinds they grinded hours earlier at 6 AM when they opened

4) Nespresso is one of the few coffee companies in the world that grinds their beans in an
OXYGEN-FREE CHAMBER (similar to vaccuum chamber) where all the oxygen is sucked out & replaced with INERT nitrogen so there is no oxidation -
then
it's hermetically sealed air-tight in
RECYCLABLE aluminum capsules with a food safety liner on the inside so that the coffee grinds never touch any oxygen nor aluminum either

==
P.S.

5) Avoid capsules that use plastic -the high heat/pressure in the machine might cause some of the plastic to leach into your coffee

Avoid paper capsules/coffee bags UNLESS they are have a plastic or aluminum lining on the inside or else oxygen will permeate thru

The standard ONE-WAY vents you see on some coffee bean bags is to because beans/grinds slowly release gas aromas as they sit on the shelf so use them before the 'Best by date' -you can still use them afterwards but it won't taste so good

For Nespresso pods it's decent, and yes they are pretty much worth the price.

You can also just make instant coffee and it won't taste as good as the original nespresso pods.
