Fermtech Double Blast Wine Bottle Rinser Beer Bottle Washer Review (2026)

How it works

The Double Blast sits in a sink and connects to a faucet with a length of tubing rather than mounting directly on the tap. Pressing a bottle down over either of the two spring-loaded jets triggers a blast of water inside the bottle, and lifting the bottle off stops the flow, so water only runs while a bottle is actually being rinsed. Having two jets side by side means a brewer or winemaker can rinse two bottles in roughly the time it would take to rinse one on a single-jet washer, which speeds up the slowest part of most bottling sessions. The maker states the unit is temperature resistant to 140F, so hot tap water can be used without damaging it.

Water use and sink setup

Because the washer sits in the sink and is fed by tubing rather than clamping onto the faucet spout, the maker states it eliminates the stress and water-hammer risk that faucet-mounted washers can put on plumbing, and the wide base is designed to keep the unit stable in a standard sink rather than tipping during use. The maker also states the Fermtech design uses less than half the water of conventional brass bottle washers, since the jets only spray while a bottle is pressed down rather than running continuously. For anyone bottling a full 5 gallon batch, that difference can add up across roughly 48 to 50 bottles.

Faucet compatibility

The listing includes a laundry tub faucet adapter to connect the tubing to a threaded spout, which works well for utility sinks and any faucet with standard threading. Kitchen faucets are more likely to have a pull-out sprayer, a non-threaded spout, or another fitting the included adapter was not designed for, so some kitchen setups may need a separate adapter purchased on top of what comes in the box. Checking the shape of a kitchen faucet before buying is worth doing if a laundry or utility sink is not available to rinse bottles in instead.

What it does not do

This washer rinses with plain water; it does not sanitize. Rinsing with the Double Blast removes loose residue, dust and any dried remnants left in a bottle after storage, which makes the sanitizing step that follows faster and more effective, but a brewer or winemaker still needs a separate no-rinse sanitizer soak or spray before filling bottles. Treating this as a pre-sanitizing rinse station rather than a full cleaning solution is the right way to fit it into a bottling day routine and keeps expectations realistic about what the tool actually does.

Who should buy it

The Double Blast fits homebrewers and winemakers who bottle full 5 or 6 gallon batches regularly and want to cut rinsing time roughly in half compared with a single-jet washer, especially anyone with a utility or laundry sink where the included adapter threads on without extra parts. It is a less obvious fit for someone whose only option is a modern kitchen faucet with a non-threaded or pull-down design, since they may need to source a separate adapter first. Paired with a no-rinse sanitizer, it turns bottling day rinsing into one of the faster steps in the process rather than one of the slowest.
