Quick Answer: A plastic pour spout fits into the neck of a bottle and slows and steadies the flow. It does not measure: one US standard drink of spirits is 1.5 fl oz (NIAAA), and only a jigger or a measured pourer checks that. Esatto sells plain plastic pourers in packs of 13, 50 and 100, and a lidded version in packs of 12. Plastic suits many pourers on ordinary bottles. Bottles that sit open need a lid or cap.
Plastic pour spouts are the simplest pourers you can put on a bottle. This guide covers what they do and do not do, how they compare with the stainless steel pourers on the same shelf, and when a lid earns its place. The plain packs are on the Other Esatto Pourers page, and the lidded style is in the Pour & Seal collection.
What does a plastic pour spout do?
It slows the flow of liquid out of a bottle and steadies the stream. That is all it does. It does not measure. In the United States one standard drink of spirits is a 1.5 fl oz (about 44 ml) pour at 40% alcohol (NIAAA, checked September 2026), and a plain pourer cannot tell you when you have poured that much. A jigger, a measured pourer or a practiced count does that job. Screenpourer.com has a comparison of free-flow and measured pourers if you are choosing between the two.
How do plastic and stainless steel pourers compare?
The Esatto product pages are the only source here, and they publish no pour rates for any pourer, so this post gives none. What the listings do show is below.
| Trait (source: the Esatto product pages, read September 2026) | Plain plastic packs | Stainless steel listings |
|---|---|---|
| Pack sizes | 13, 50 and 100 | 2, 6, 24 and 50 |
| Colors | Black, blue and red (the 100-pack is black only) | Chrome, copper, gold and black |
| Lid or cap | None mentioned on the plain plastic pages | Flip lid, hinged lid or dust caps, depending on the listing |
| Wide necks | Adapters not mentioned | Several listings name adapters for oversized or wide-mouth bottles |
| Flow | The 50-pack is titled "Medium Flow" | One listing is titled "Fast Flow"; several mention an anti-drip airflow design |
When is a plastic pourer the right pick?
When you need a lot of matching pourers on ordinary bottles. The 100 Pack Plastic Pourer, Black is the largest pack of pourers on this site. Smaller counts include the 13 Pack Plastic Pourer, Black and the Plastic Pourer 1 Piece, Medium Flow, Pack Of 50 Pieces, Black. Pack size is the practical difference between the two materials in this catalog. If you want to sort bottles at a glance, the colors give you a way to do it, though that is a habit you would set up yourself, not a feature the pages describe.
When is a plain plastic pourer the wrong choice?
There are three cases. First, a bottle that sits open between uses. A plain pourer leaves the channel open. Fruit flies are drawn to fermenting food and to wine, beer, fruit juice and vinegar, and the University of Maryland Extension (checked September 2026) says the primary control is sanitation. A lid or cap closes the opening, but it does not replace cleaning, and there is a separate guide to keeping fruit flies out of liquor on screenpourer.com.
Second, a wide neck. The plain plastic pages do not say which necks they fit, so check yours before you buy a pack. The Pourer P&s, Black 12 Pieces With 4 Cork Adapters Included lists four cork adapters for various bottle sizes. Third, measuring. A plastic pourer will not do it for you, as covered above.
Where the Esatto Plastic Pourer With Lid, Pack Of 12 Pieces, Black fits
Esatto makes and sells the Plastic Pourer With Lid, Pack Of 12 Pieces, Black. It is our own product, not an independent pick. Its page says that leaving bottles open exposes the liquor to debris and fruit flies, and that the built-in lid lets you seal the bottle easily. It also comes in blue and red. It is the wrong tool for a wide neck unless you choose the listing with cork adapters, and like every pourer here it does not measure. The stainless steel Esatto Stainless Steel Liquor Pour Spouts with Flip Lids are the metal alternative with a lid.
Frequently asked questions
What is a plastic pour spout?
A plastic pour spout, also called a plastic pourer, is a spout that fits into the neck of a bottle so the liquid leaves in a slower, steadier stream. Esatto sells plain plastic pourers in packs of 13, 50 and 100, and a version with a built-in lid in packs of 12.
Is a plastic pourer or a metal one better for a bar?
The listings do not show either material beating the other on a measured trait, and no pour rates are published. The differences are practical: pack size, whether a lid or dust caps come with it, and whether adapters for wider necks are in the box. Choose on those.
Do plastic pourers fit every bottle?
Not necessarily. The plain plastic pages do not say which bottle necks they fit, so check your neck first. Wide-necked bottles need an adapter. The Pourer P&s listing with 4 cork adapters includes them, and so do several stainless steel listings.
Does a plastic pourer keep fruit flies out of a bottle?
A plain plastic pourer leaves the channel open, so on its own it does not. The University of Maryland Extension says the primary control for fruit flies is sanitation. A lid or cap closes the opening between pours, but it does not replace cleaning.
Can a plastic pourer measure a shot?
No. It slows and steadies the flow. A US standard drink of spirits is 1.5 fl oz at 40% alcohol, according to NIAAA, and a jigger or a measured pourer is what checks that amount.
What colors do Esatto plastic pourers come in?
The 13-pack and the 50-pack are listed in black, blue and red. The 100-pack is listed in black. The 12-pack with a built-in lid comes in black, blue and red.
Do plastic pourers come with lids?
Some do. The Plastic Pourer With Lid has a built-in lid. The plain 13, 50 and 100 packs mention none on their pages.
