I checked the titratable acidity (TA) of my cherry mead the other day, and something didn’t add up. Over six months, three measurements, and two acid additions (totaling 2.6 g/L) the TA fell from 6 to 5.5 g/L.
The most obvious explanation is that I goofed up the titrations. As I added more acid, the TA […]

Cherry Mead: The case of the disappearing acid
Suppose you measure 6 g/L titratable acidity (TA), then add about 1.3 g/L of tartaric acid. After you let it sit for a while you’d expect a TA over 7, right? Me too. You certainly wouldn’t expect just a little over 5 (call it 5.2), would you? I […]

Chocolate Wine: How to make it

How to use chocolate in wine
Should chocolate be the main ingredient in the wine? Put another way, should everything else in the wine be there just to make sure there is enough alcohol, sugar, and acid for the wine to be … well a wine? That’s how I made my oregano wine, and it looks […]

Peapod Burgundy?

This blog is about making wine, so I don’t talk about my vegetable garden very much. My gardening and winemaking overlap in some ways like rhubarb wine, oregano wine, tomato wine, and the one-pint (500 ml) batch of wine from my own grapes. Well there’s going to be some more overlap this year, because I’m […]

What do you need to know about chocolate to make wine with it? That’s what I want to focus on in this installment of my Know Your Ingredients series. So I’ll be skipping over most of the history of chocolate and the details of how its made, unless they help illustrate something about how chocolate […]

Know Your Honey: Acid and lactone

I’ve begun reading Composition Of American Honey by Jonathan White, which was published in 1962 by the US Department of Agriculture as Technical Bulletin 1261. It’s the most comprehensive survey of honey ever conducted, or likely to be conducted anytime soon, in the US. Reading it made me want to post about honey in my […]

Rhubarb Wine With No Added Water?

I make rhubarb wine every year. I get about 6 fl oz/lb (400 ml/kg) of juice when I thaw frozen rhubarb, and since I use about 3 lb/gal (360 g/L) of rhubarb I need to add a lot of water. But 6 fl oz/lb scales up to over 4.5 gallons from 100 lb of “fruit.” […]

A wine to match the occasion
A couple of weeks ago, I passed along some great advice about pairing wine and chocolate for Valentine’s Day. That got me thinking about making a wine for the Day of Romance. What should the wine be like? At first, I thought it should pair with chocolate, like those earlier […]

I talked about five of my meads yesterday, and how I might decide if they were ready to bottle. I looked at clarity and specific gravity (SG) because I didn’t want the mead throwing off sediment or fermenting in the bottle. I tasted, probably the most important test of any wine or mead, and I […]

I looked in on five meads yesterday to see if they were ready to bottle. I was looking for clarity, I tasted them to see if they were pleasant to drink, and I measured the specific gravity (SG), pH, and titratable acidity (TA).
