49% Guitar Humidifier, Size 320, Single - Large Instrument Display

Unlike grains, seeds, coffee or mayonuaha, puerh tea is a living material. It ages and improves for years and even decades. If it is left in contact with the tiniest bit of odor, it will absorb it and return it all during drinking. Thankfully, the Boveda is absolutely odor-free and perfectly suitable for tea aging. This has been verified not just by me, but also by a whole community of tea collectors over the years. If you’re new to aging tea, keep reading. Green tea should be drunk within two months of opening. Any later and it develops harmful toxins. Oolongs are more processed and should be drunk within about a year or so. Oolongs do not usually develop toxins but do deteriorate and should be kept in sealed original packaging. Puerhs (especially sheng puerhs) and white teas are minimally processed, intentionally. They still contain live enzymes, live of bacteria and live yeasts. This is why some of the best stuff comes from forests. It also means that aging requires a certain humidity level. Bacteria and yeasts do not have legs. They do not spread under 71% relative humidity. Under this threshold, they will work in moderation and in sync with the enzymes. Above this threshold, they will spread and overpower the tea with earthy, woody, mushroomy and sometimes metallic or pungent aromas and flavors. Most people are into the lighter fruity and floral flavors that you only get under 71% relative humidity. So make sure you know what you are going for, if you’re using Boveda humidity packs to age your tea. Keep in mind that your cake or tong is probably around 50% rel. humidity by the time it reaches you. Its humidity will average out with this pack. You will be well under 71%. There’s really no difference between say 55% and 70% for ageing. All the enzymatic, bacterial and fungal processes probably work at a constant rate. 50% rel. humidity is probably too low and may halt aging altogether. The tea will still lose its youthful flowery tones, but without gaining the smooth and deep texture of aged tea. I use the 49% pack to bring down teas previously stored above 70%. It’s also important to always stay above 68°F (ideally 70-80°F), and absolutely imperative to avoid exposure to light. I use large steel canisters, which I thoroughly clean and bake in an oven at 500°F, before use. They come covered in oil residue from production that cannot be cleaned by household cleaning agents. This residue get burnt off together with its odor and easily wiped with a neutral cotton towel afterwards. I clean and wipe the silicone rubber seal ardently. My steel canisters are each filled densely with teas of similar character. They contain no paper other than production wrappers and no synthetic packaging. I store them in a warm bedroom without unpleasant smells.

Great product. Keeps those guitars from getting parched. Be aware that this particular unit is big and for guitar collection cases and not individual guitar cases.

Good product even though I bought the wrong one

These things work beautifully. I use them is gun cabinets and cigar humidors. My wife uses one in a sugar canister. The different % humidity packs make them very useful for precise control.

Bought them to humidify a cabinet converted for ukulele storage. They work great, maintain promised humidity levels.

... only works in very small areas such as a small box. Even in a guitar case it could not keep the humidity level anywhere near 49 percent, more like 32 percent.

Great product I use them all the time

I throw one of these in my 100 stick humidor every 3 months. Wish they were cheaper, but the ease of use is unmatched.

Doesn't quite make it to 49%

Hällt Luftfeuchtigkeit, aber eher ungenau. Achtung keine Bags für Gitarre dabei (wie abgebildet) Also sehr teuer! Gibt bessere Lösungen für den Gitarrenkoffer!
