Question: Does it need a filter?
Document: Would have really liked to have a strainer included. This is only an aerator, and doesn't filter out sediment. My mistake.
Zazzle immediately returned my emails, refunded the cost of the broken aerator AND sent out a new umbrella part to fix the ailing aerator. I couldn't ask for better communication and outcome from a customer service experience. If I need more, I'll be buying from Zazzol.
I guarantee that there will be a noticeable difference with most red wines (some red wines do not need to breath).Do not expect to notice any difference, or at least much difference, with aerated white wines; white wines generally do not improve when allowed to breathe.I cannot compare the Zazzol Wine Aerator with other brands as I have not tried any others.
I used this to replace a wine soiree I purchase many years ago. This might do a slightly better job but it does it with a lot less mess and hassle; it is a very good product and gives you near instant decanting. I have some wines that I use this for and allow them to sit for another hour or two but otherwise they need 24 to 48 hours to have the same taste.
I am not a sommelier or oenologist. As a hobbyist, I have my favorite vintages and varietals. Those did not include many of the &#34;sophisticated&#34; wines, which I chalked up to less than sophisticated palette. Now instead of skipping the cabernet sauvignon, merlots, and sauvignon blancs, I am discovering the richness that I'd never extracted from them before. Using this aerator is quick and fool-proof, eliminating the need for decanting and waiting.
With the Zazzol Wine Aerator, there is no need to rush; the large capacity pouring cavity eliminates that issue. There are also no holes in the sides as others have so no worries about covering the holds by mistake with your hands (and getting wine all over yourself) and having it drip onto the table or floor.This works product works great whether you are an experience wine connoisseur or a novice. It works with expensive wines as well the lower priced ones.
Often, in bottles that have just been open, there is an acrid flavor which means you need to let your wine set and breath for some time. The Zazzol Wine Aerator easily breaks down tannins that can cause the dry and acrid flavor found in freshly opened wines. I was introduced to wine aerators by a friend, who has a different type, where the bottle must fit over the wine and you must pour quickly and faster to avoid spilling the wine on the table or floor.
would like decanters to fully enjoy the aerators the difference it made n the wines amazing would recommend this device to all wine drinkers
went from the box to the sink (to be washed) and then immediately used -makes all my favorite wines....better! we've lived in the Willamette Valley of Oregon and have enjoyed some of the best wines - we enjoy wines from our local winery as well and have always enjoyed them. we now enjoy them much more! (it also makes a $4 bottle of wine more palateable)worth every cent
it is well packed, easy to use,  beyond my expections and the price is reasonable. I love it. Strongly recommended.
Answer: No filter needed. That is to say, the wine aerator does not use a filter.
